Product Description
Product Overview
The PCF series ceramic resistors are designed for anti-pulse surge applications, featuring KOA's original bulk ceramic resistor technology. These resistors offer excellent in-pulse and inrush current characteristics, along with higher reliability against disconnection compared to wirewound and film resistors. They are non-inductive and equipped with a flame retardant coating (equivalent to UL94V0). Products meet EU RoHS requirements and are AEC-Q200 tested, making them suitable for demanding environmental applications.
