Product Description
Product Overview
The PCF series ceramic resistors are designed for anti-pulse surge applications, offering superior in-pulse and inrush current characteristics. These KOA original bulk ceramic resistors feature a flame retardant coating (UL94V0 equivalent) and are non-inductive. They provide higher reliability against disconnection compared to wirewound and film resistors and are AEC-Q200 tested. Products meet EU RoHS requirements.
