KOA's High Energy Pulse Withstand Resistors

KOA's High Energy Pulse Withstand Resistors

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 pulse voltage
5W power rating up
Operating temperature up to +200 °C
PCF: Flame retardant coating (equivalent to UL94 V-0)
HPC: AEC-Q200 qualified

Application Examples

High voltage circuits
Medical HV-products
Power supplies
Inrush current limiting
Snubber circuits
HV dividers
X-ray generators
Electron beam microscopes
Replacement for solid carbon resistors
