Schurter Announces the FMBB EP Single Phase Filter

Schurter Logo1.jpg

Single Phase Block Filter with Excellent Performance
• Ultra compact double stage filter
• Excellent symmetrical and asymmetrical attenuation
• Very broad band attenuation
• Completely closed steel housing

Schurter completes its portfolio of ultra-compact single-phase filters with a new generation of particularly high-performance thanks to a double stage filter design. FMBB EP is the name of the latest member in the completely closed steel housing.

Ever more powerful and at the same time ever more compact design – these are the requirements for state-of-the-art electronic devices. The filters of the FMBB EP family are particularly suitable wherever such equipment is confronted with stubbornly high EMI interference signals. Highly clocked semiconductors generate increasingly strong interference frequencies. This massively increases the requirements for compliance with EMC. Typical applications include test and measurement equipment, professional kitchen equipment, medical and critical industrial applications.

Identical Housing Dimensions
The new filters use the same housings as the proven FMBB NEO filter series. These housings are spot welded, thus completely closed, resulting in significantly improved attenuation behavior. Thanks to topquality components (generously dimensioned film capacitors, chokes with highly permeable cores), an exceptionally broad-band attenuation is achieved.

Mounting
The FMBB EP filter series has 6.3 x 0.8 mm plug-in connections or threaded connections for quick and easy wiring. Thanks to a metal flange, excellent ground connection is ensured when screwed to the chassis.

Wide Temperature Range
The standard versions can be used over a temperature range from -40 °C to 100 °C. The filters are designed for currents from 1 A to 36 A at an ambient temperature of 40 °C. They have ENEC and cURus approval and are recommended for applications up to max. 250 VAC.

Leakage Current
There are versions with different leakage currents available for different applications: the standard version with 0.9 mA to 3.8 mA, for medical technology ≤ 5 µA or ≤ 80 µA.

Schurter Logo1.jpg

Schurter is launching its new CPS family of push button switches with capacitive touch sensor technology inside. The new switch family caters to the latest technology trend for robust momentary and latching push button switches while sporting an elegant modern look that makes them the perfect choice for use in applications wherever a high quality aesthetic appearance plays a role. In addition to an IK rating 09 and IP rating 67, the series offers a predefined standard range with many visual and functional options to choose from. These features allow the customer to adapt the push button, or the switch in general, to their individual electrical and mechanical requirements.

Metal push button switch with capacitive sensor technology offers latching-action with optical feedback:
The CPS series uses capacitive sensor technology, whereby a touch of the finger on the sensor area causes a change in the electrical field which in turn causes the switch to change its state; this occurs without any pressure on the actuator. The capacitive touch technology eliminates the need for any moving parts, hence making the CPS a long-life product capable of an unlimited number of actuations. The CPS actuator expands further on actuation options with a so-called finger guide, which is designed to enhance the user experience.

The CPS series is made of high-grade stainless steel in 16 mm, 19 mm and 22 mm diameter housings. The variable input supply voltage is 5 – 28 VDC. Switching voltage is max. 42 / 60 VAC / VDC. Switching current is max. 100 mA. Operating temperature range is -20°C – +60°C. A wide range of illumination options, starting with the selection of a ring illuminated or area illuminated version, are offered. The area illuminated version is made of scratch-resistant biocompatible ceramics. A single color, bicolor, or multicolor configuration is possible. Besides the basic colors red, green, and blue, the CPS also offers additive colors like cyan, magenta, yellow, and white for custom color variations.

The CPS can easily be customized to specific customer requirements by simply choosing from a list of options in the configurator list provided in the data sheet, or according to application specific requirements beyond what is shown.

Schurter Logo1.jpg

Mains Filter: 3-Phase plus Neutral Line
• Compact Single-Stage Filter
• Various Filter Variants Available
• Light Weight Design, Wide Temperature Range
• “High Performance” Versions Available

FMAD CP is the name of the latest 1-stage filter family for 3-phase systems with neutral conductor. Thanks to their extremely compact dimensions and high performance, the new filters are ideally suited to the tight space conditions in today’s machine and equipment construction. An extended temperature range means that they can also be used in critical applications.

The new filter family is ideally suited for devices with high EMC exposure at low or medium power. Typical applications include converters for photovoltaics, battery storage or charging stations for electric vehicles. These powerful, particularly compact filters are also the first choice for modern frequency inverters for motor control.

Mounting
The FMAD CP filter series has 6.3 x 0.8 mm plug-in connectors for quick and easy wiring. Thanks to a metal flange, a good earth connection is guaranteed when screwed to the chassis.

Wide Temperature Range
The standard versions can be used over a temperature range of -40 °C to 100 °C. The filters are designed for currents from 3 A to 20 A at an ambient temperature of 50 °C. They have ENEC and cURus approval and are recommended for applications up to max. 520 VAC.

Leakage Current
Versions with different leakage currents are available for various applications: for industrial ≤ 3 mA, standard ≤ 0.5 mA and for medical technology ≤ 5 µA.

“High Performance” Version
Although the new filter family is already equipped with very high-quality components, an even stronger filter effect might be required for particularly demanding applications.

Schurter UMT-W Super Time-Lag SMD Ceramic Fuse

Schurter Logo1.jpg

Super Time-Lag SMD ceramic fuse with selective tripping characteristic

• Suitable as a Fail Safe Device
• Very high melting integral
• Precisely defined melting times (min/max)
• Compact construction

With the UMT-W, Schurter launches a pulse-proof SMD ceramic fuse with super time-lag tripping characteristics, which is particularly suitable as a fail-safe device in demanding applications.

The cuboid shaped (5.3 x 16 mm), extremely compact SMD fuse is available in five rated currents from 5 A to 20 A and reaches rated voltages of up to 125 V AC&DC with a breaking capacity of up to 1000 A. All these you get with a super slow and precisely defined melting characteristic unique for SMD fuses.

Applications
The Schurter UMT-W is recommended wherever high inrush currents flow (e.g. motor control systems). The UMT-W is particularly suitable for applications with long cables (e.g. avionics), which are often primarily protected by an electronic fuse. If this monitoring fails, or does not perform its task correctly, the UMT-W takes over as a fail-safe device and transfers the system to a safe, currentless state. Due to the precise melting times with its precisely defined min/max corridor at 4xIn, robust and selective safety concepts can be implemented on top of the electronic fuse.

COTS+ The UMT-W fuse is a “COTS+” product. The “+” comes from extended fuse qualification tests (e.g. AEC-Q200) and highly controlled manufacturing processes, which are available to all SCHURTER customers. For higher reliability requirements, we also offer visual inspection according to MIL-PRF 55342, different types of up-screenings (burn-in) and detailed test reports on request.

Schurter C20F Appliance Inlet with Filter

Schurter Logo1.jpg

• Variants with ground choke
• Highly resistant – fully potted
• Interrupts ground loops
• V-Lock cord retention

Schurter extends its successful power entry module series C20F with versions including a ground line choke, designed for suppressing high-frequency interference on the ground conductor. Additionally, the new variants have a bigger X-capacitor for better symmetrical attenuation.

The C20F filter series combines an IEC C20 appliance inlet with a high-quality mains filter. The particularly wide metal flange makes contact with the housing surface over a large area, thus enabling optimum filtering and shielding.

 

Ground Choke
New variants of the C20F appliance inlet filters are equipped with a ground choke. The line filters have a second choke on the earth conductor in addition to the current-compensated choke on the pole and neutral conductor. The ground choke is located between the device plug and the filter output. Placing it directly at the mains input ensures that possible high-frequency interference currents on the earth conductor cannot bypass the filter via the housing. Medical filters in particular (no Y-capacitors) benefit from improved asymmetrical attenuation in the higher frequency range due to the ground choke.

Applications
The C20F filter series is available as standard or medical version and is used in devices that require a particularly high noise immunity. These include IT or telecom systems according to IEC 92368-1 and medical devices according to IEC 60601-1. The series is compatible with V-Lock device connection cables.

The C20F series is certified for currents up to 16 A / 250 VAC according to IEC standard and 20 A according to UL/CSA standard at 125/250 VAC. It provides ENEC, CQC and cURus approvals.

Schurter AEO 10.3×38 Fuse

Schurter Logo1.jpg

High Performance Fuse For Automotive Applications
• Very high rated current up to 50 A
• Safely interrupting 1000 VDC
• Versatile mounting options

With the AEO 10.3×38, SCHURTER launches a high-performance fuse for particularly high voltages up to 1000 VDC and currents up to 50 A, which is particularly suitable for automotive applications.

High voltages and high currents occur in electric vehicles in numerous places. Their battery packs with several thousand rechargeable cells store enormous amounts of energy. This in order to meet customer requirements concerning driving performance and range by still providing the shortest possible recharging times. To safeguard this level of power, you need highly reliable high power fuses. Such fuses are required, for example, in the BMS (Battery Management System), for on-board and off-board chargers, DC-DC converters and other systems exposed to high voltages.

Welding Is More Reliable
A weak point of every fuse is the connection between the melting wire and the contact cap. This connection is usually done by a solder joint. In the fuse production process, however, this technology brings quite many difficulties. Creating the connection by welding increases the reliability by far. SCHURTER uses a new, patented process which guarantees highest reliability.

Versatile Mounting Options
The new fuses of the AEO series offer a multitude of possible mounting options. In addition to the cartridge fuse, which requires a fuse clip (recommended model: SCHURTER CSO) and the classic mounting directly on a printed circuit board, screwable version for surface mounting or even axial mounting are available.

Applications Automotive:
DC/DC Converter, On Board Charger, Battery Management System, PTC-Heater and Houshold Charging Stations.
