High Voltage Tubular Resistors

Series 800 and 1000 Tubular Non-Inductive Bulk Ceramic Resistors provide excellent performance for high peak power or high-energy pulses. Bulk construction advantageously produces an inherently non-inductive resistor; and it allows energy and power to be uniformly distributed through the entire ceramic resistor body – there is no film or wire to fail. We offer a full line of rugged, reliable ceramic resistors.

* Allowable peak energy/voltage will depend on the resistance value. Consult factory.

** Derate by 50% with oil resistant coating on Type AS resistors. Energy ratings are based on pulses <10 milliseconds. Type SP ratings can be substantially greater for longer pulses. Consult factory.
