FILTER:PREVENTFENCE

In industrial control cabinets and medical equipment, electromagnetic interference can disrupt sensitive electronics and cause compliance failures. The Ricoh D0146978 power line filter addresses this by attenuating conducted emissions on single-phase AC lines. With a rated current of 10 A and voltage up to 250 V AC, it is suitable for a wide range of IT, industrial, and medical (non-patient contact) applications. Its dual-stage design combines common mode and differential mode filtering to deliver reliable suppression from 150 kHz to 30 MHz.
