PCB mounted chokes for 1- and 3-phase applications

DKIH series

Designated the DKIH series, the chokes are available for single and three phase applications with rated currents from 10A to 50A.

To meet EMC requirements there are advantages to design a filter on PCB with discrete components, according to the supplier.

“Capacitors and a common mode choke, with asymmetrical effective inductance, are very effective to dampen EMI noise,” said Schurter.

The common mode chokes can be placed on the PCB with through-hole technology. They are designed and approved according IEC 60938, UL 1283 and CSA 22.2 no. 8. The voltage rating is 300Vac (IEC, UL) and 250Vac (CSA).

The operating temperature range is -40 to +100°C.

They are available with a standard pin out or customer specific pin out. Variations in the winding are also available on request.
