The "C" series of epoxy coated, radial lead resistors can absorb high energy at voltages up to 44kV. They are ideal for high voltage applications requiring non-inductance, as in pulse-forming and fast crowbars. Typical uses are in high voltage test equipment and cardiac defibrillators.

Pulse Voltage Limits

The pulse voltage capability of the C series of Cercomp© resistors is constrained by allowable current, energy, and especially pulse width. The two graphs presented below show allowable peak impulse voltage vs. resistance for two standard waveforms which typify actual operating conditions. The waveforms are defined by the rise time, (to 90% amplitude), and the pulse width, (decay to 50% amplitude). Please consult Applications Engineering at HVR Advanced Power Components to verify safe operating area compliance for your application.
