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 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.

Schurter UAI 1206 Chip Fuse

Schurter Logo1.jpg

Chip Fuse for Highest Demands
* Pulse- and temperature-resistant non-aging chip fuse
* Sealed against potting compound
* Meets requirements according to AECQ

With the UAI 1206, Schurter offers a pulse and temperature resistant chip fuse with time-lag characteristics for applications where durability and maximum reliability are requested.

Conventional fuses have a sort of memory. If they are exposed to pulse-shaped current peaks and high temperature fluctuations, their properties change. Every pulse makes the fuse a little weaker, every temperature fluctuation a little more susceptible. Not so with the Schurter UAI 1206.

 

Pulse and Temperature Resistance
Because of the a special fuse construction, dubbed by SCHURTER as “trace in air” technology, the UAI’s ability to resist current pulses smaller than the melting integral (I2t) is thereby increased exponentially. Comparably, the UAI 1206 has practically no derating to the usual extent. The ingenious design of the fuse body also dampens temperature fluctuations to a high degree. The SCHURTER UAI 1206 is also hermetically sealed against potting compound for use in intrinsically safe applications.

Areas of Application
The new chip fuse, which is offered in two versions with rated currents of 5.3 A and 7.5 A, was specificially developed for automotive applications. The Schurter UAI 1206 meets all requirements according to AEC-Q200. It is also suitable wherever high levels of pulse currents, high thermal fluctuations, and high mechanical loads are present.

Schurter Logo1.jpg

* Very high melting integral (I2t)
* Variants up to 50 A (Pigtail)
* Clip and Pigtail versions
* Excellent price-performance ratio

With the SUT-H, Schurter introduces a new 6.3×32 mm ceramic fuse for single-phase applications for high rated currents from 10 A to 50 A. Thanks to a particularly high melting integral, it is particularly suitable for applications where high inrush currents occur.

The new Schurter SUT-H is technically based on the proven SUT. In contrast to the known fuse, the SUT-H has a much higher melting integral, which makes it particularly pulse resistant. High inrush currents, which occur in power supply units, are easily absorbable.

The fuse is offered for direct mounting on the PCB with pigtails or with a solid beryllium-copper clip (Schurter CQP), which allows an easy replacement of the fuse without soldering. The clip can be up to a rated current of 10 A.

The new 6.3×32 mm SUT-H ceramic fuse opens up completely new areas of application by extending the rated current range up to 50 A and opens completely new areas for innovative applications.

Schurter MGA-A 1206 SMD Fuse with 125 VDC

Schurter Logo1.jpg

* No tin whiskers, no tin dendrites
* Lead-free coating (RoHS conform)
* Similar fuse qualification as in MIL-PRF 23419
* Hermetically sealed and robust construction

Schurter extends its successful MGA / MGA-S line of 1206 dimension SMD ceramic fuses with an aviation version that is tin whisker free and completely dispenses with leaded coating.

Crystalline tin dendrites and tin whiskers pose a considerable risk of short circuits in highly dense electronics. Dendrites form during the electro-deposition process, whereby heavy marks could appear on the fuse end caps or housing. A thorough inspection and cleaning is required according to MIL-PRF 23419. Tin whiskers form after the electro-deposition process. The cause is not well understood, although adding lead to otherwise pure tin soldering is commonly used as a preventable measure.

However, lead has become an unwanted element according to many environmental initiatives, e.g. RoHS directives. For this reason, Schurter has extended the successful SMD thin-film fuse family MGA with the new –A variant. In addition to the classic MGA and the ESA-certified MGA-S space fuse, the aviation version, MGA-A, uses gold alternatively to lead. Gold plated end caps provide a surface where neither whiskers nor dendrites can form. This makes the new MGA-A a safe solution for use in not only highly sensitive electronics in the aviation industry but often suffices for use in the industrial grade space sector.

The technical design is similar to that of the ESA-certified MGA-S. This means: hermetically sealed, ultra-robust construction, which is ideally suited for use in intrinsically safe applications according to ATEX and IECEx requirements. Despite its very small footprint (1206), the MGA-A has a particularly high breaking capacity of up to 300 A at 125 VDC and can be used in a wide temperature range of -55 °C to +125 °C.

The new MGA-A from Schurter is suitable for all applications where the highest demands are placed on reliability and availability.
