High Voltage Power Bulk Ceramic Resistors
(RMCD)Introduction (RMCD)
Tubular Bulk Ceramic Resistor Offers Higher Energy Power Dissipation & Higher Voltage Withstand.
Power High Voltage Dividers and Resistors Type RMCD extend Token Electronic's advanced proprietary high voltage resistor technology to larger devices than have previously been available on the market.
The RMCD is the bulk non-inductive ceramic tubular resistor. Because of the larger volume of resistive material, these resistors are capable of handling significantly higher pulsed power than their wirewound or metal film counterparts, making them suitable for rapid energy dumping and high energy pulse work.
This RMCD offer higher average power dissipation while retaining the advantages of high surge energy, high voltage withstand, and non-inductance. It is especially useful in RF applications such as transmitters and modulators, where the tube configuration provides more effective convection cooling.
In addition, this RMCD HV resistor and divider provides high peak voltage and power energy combined with extremely high working voltage. These specifications can provide important improvements in performance in many types of advanced electronic systems, including TWT power supplies, radar systems, X-ray systems, analytical equipment and high resolution CRT displays.
Token will also produce devices outside these specifications to meet customer requirements, with comprehensive application engineering and design support available for customers worldwide. Contact us for details with your specific needs.
