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

  • Is reliability and enhanced terminal strength essential in your power application

    KOA's WK73-series has a 90° rotated design and offers several advantages compared to standard resistor footprints. A three times higher power rating in case of 0612 vs 1206 size is the most visible. This can save board space and is based on the improved heat dissipation through the solder joints. Much higher terminal strength is related to the bigger soldering area. The lower distance between the terminals, results in less expansion stress to the solder joints. The inner resistive pattern causes less temperature rise. All the above mentioned benefits combined, result in a superior reliability compared to standard flat chip resistors.
