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