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, with a flame retardant coating equivalent to UL94V0. They provide higher reliability against disconnection compared to wirewound and film resistors and are AEC-Q200 tested. Products meet EU RoHS requirements.

Product Attributes

Brand: KOA
Material: Ceramic
Coating: Flame retardant (Equivalent of UL94V0)
Certifications: EU RoHS compliant, AEC-Q200 Tested
