Common Mode Chokes for 4 line Applications mount on PCB
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 metehod for 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.
