Nov 24, 2023The DKIH-4 series is available for three phase applications with neutral line at rated currents from 10 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 for suppressing EMC interference. The common mode chokes are designed according IEC 60938 and rated 500 VAC or 760 VAC and will operate in a wide temperature range from -40 to +100°C.
