Resistors And
Resistive Applications
CTR
High Voltage Resistors - High Power Resistors - High Energy Resistors
■
FEATURES
Series 800 and 1000 Ceramic Tubular Resistors(CTR) 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.
