Common Mode Chokes for 4 line Applications mount on PCB
• Compact size and light weight
• Open design for optimal cooling
• Nanocrystalline ring cores
• Customer specific pin configurations available

Schurter expands its successful range of current-compensated chokes with a series for 4-wire high-current applications on printed circuit boards. The new DKIH-4 series is available for three phase applications with neutral line at rated currents from 10 A to 40 A. Due to the open design, the chokes are particularly compact and light.

Like most electronic assemblies, the power section is increasingly being mounted on the printed circuit board with discrete components. However, due to the high integration density required to achieve a compact design, thermal problems can arise due to the high currents on the PCB. EMC interference can affect adjacent modules due to the lack of spatial separation. Therefore, a compact filter on the PCB with discrete components is often the best solution. A current-compensated choke with capacitors is the most efficient method of suppressing EMC interference.

The new DKIH-4 series is suitable for three phase applications with neutral line from 10 A up to 40 A . Light weight and compact, the common mode chokes are easily placed on the PCB with through hole technology (THT). The common mode chokes are designed according IEC 60938 and rated 500 VAC or 760 VAC, making them suitable for almost any applications.

The DKIH-4 has been designed for a wide temperature range from -40 °C to +100 °C. In addition to the standard versions, customer-specific pin configurations or variants can be created on request.

Schurter DKIH-4: Ferrite and Nanocrystalline Chokes for 4-Wire Applications Mount On PCB

Schurter Logo1.jpg

DKIH-4

Schurter expands its wide range of current compensated chokes with new customer specific variants for 4-wire-applications on PCB. The new DKIH series is now available with ferrite or nanocrystalline ring core. The new product is designed for three phases plus neutral wire applications with rated currents from 10 A to 50 A. Due to its open design, the chokes are light weight and compact, ideally designed to suppress EMC noise caused by power applications on the PCB.

Like all other aspects of electronic design, the power portion is often built today using discrete components on printed circuit boards. With the trending integration of components, to achieve smaller and smaller form factors, thermal problems and high currents on the PCB can become a challenge. The resulting EMC interferences can affect adjacent modules because of the lack of spatial separation. Therefore, a compact filter on the circuit board with discrete components is often the best solution. A current-compensated choke with capacitors is the most efficient measure for the suppression of EMC interferences.

The DKIH-4 series is suitable for three phases AC and neutral wire applications from 10 A up to 50 A. The common mode chokes are also designed according IEC 60938 and are rated 600 VAC making them suitable for many applications such as UPS systems, switching power supplies, charge stations for electric vehicles and frequency converters for energy storage. The DKIH-4 has a wide temperature range of -40 °C to +100 °C. They are available with a standard pin configuration or customer specific ones. Variations in the winding are also available upon request.

Technical Data
– Rated voltage: 600 VAC
– Rated currents: 10 to 50 A at 40 °C
– Same dimensions and weight for ferrite and nanocrystalline versions
– customer specific pin outs available on request

Application
– Frequency converters for photovoltaic or energy storage
– Charge stations for electric vehicles
– UPS systems
– Switching power supplies

Nanocrystalline Common Mode Chokes for 1 and 3-Phase Applications Mount on PCB

Schurter expands its wide range of current compensated chokes with high current types for PCB mounting. The new DKIH series is now available with a nanocrystalline ring core, offering 8 times higher inductance performance than ferrite core versions in the same compact dimension. The new product is designed for single and three phase applications with rated currents from 10 to 50 amperes. Due to its open design, the chokes are light weight and compact, ideally designed to suppress EMI noise caused by power applications on the PCB.

DKIH2

Like all other aspects of electronic design, the power portion is oftentimes built today using discrete components on printed circuit boards. With the trending integration of components, to achieve smaller and smaller form factors, thermal problems and high currents on the PCB can become a challenge.
Traditional block filters might well address these challenges, but their larger package size also presents challenges due to the mentioned space constraints; therefore an asymmetrical effective common mode choke and capacitors mounted on the PCB is a better solution.

The new DKIH-1 series is suitable for single phase AC or DC applications from 10 up to 50 amperes. Light weight and compact, the common mode chokes are easily placed on the PCB with through hole technology (THT). They are designed and approved according IEC 60938, UL 1283 and CSA 22.2 no. 8. The voltage rating is 300 VAC (IEC, UL) and 250 VAC (CSA) with an inductance range of 1.6 to 6.9 mH.

The new DKIH-3 series is suitable for three phase AC applications from 10 up to 50 amperes. The common mode chokes are also designed according IEC 60938 and are rated 600 VAC with an inductance range of 0.7 to 10.8 mH, making them suitable for many applications such as UPS systems, switching power supplies, charge stations for electric vehicles and frequency converters for energy storage.

The DKIH-1 and -3 have a wide temperature range of -40 to +100 °C. They are available with a standard pin out or customer specific pin out. Variations in the winding are also available upon request.
