Tubular Resistors
High Voltage Resistors - High Power Resistors - High Energy Resistors
Series 800 and 1000 Tubular Resistors are available in a wide variety of sizes and
terminations from 2" to 24" in length and ½" to 2 " in diameter. These resistors
can handle up to 1000 watts, 165 KJ and 165 KV in resistance values from 1 ohm
to 1 megohm.

*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.
