Product Overview
The KOA High Voltage Type Resistors, specifically the HPC series for Anti Pulse and Surge applications, are ceramic resistors designed for high-voltage circuits. Featuring KOA's original bulk ceramic resistor technology, these components offer excellent impact and surge voltage tolerance, with enhanced reliability against disconnection compared to wire wound and film resistors. They are non-inductive and meet EU-RoHS requirements, with AEC-Q200 qualified data available. Ideal for demanding applications such as X-ray generators, electron microscopes, flyback transformers, and power supply circuits for machine tools, these resistors provide robust performance in high-stress environments.
