Ceramic Resistors for Anti Pulse Surge: HPC / PCF Series.

KOA’s original bulk ceramic resistors don’t use a resistive film or wire element – the whole body is the resistive element.

This construction results in an extremely robust device capable of absorbing high pulse currents and voltages.

Product Features:

• Solid ceramic resistor body ideal for HV and surge currents
• Non-inductive
• 25kV…
