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 wire wound 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 provide 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. For

 General Information

Cost Effective Complete Selection of High Voltage Components

Token high voltage series can be specified for use in industrial and general purpose high voltage systems,

as well as a complete selection of high resistance, Hi-Meg, high-voltage, high frequency, and bulk

ceramic resistors for higher average power dissipation. These High Resistance, High Frequency, High

Resistance resistors combine the proven performance of Token resistance system with new cost efficient

design elements and high voltage applications.

Detailed specifications, both mechanical and electrical, please contact our sales representative for more

information.

High Voltage Applications

Resistors produced from Serpentine Pattern Screen Printing Design or bulk ceramic materials have

displayed several key advantages in demanding high-voltage situations, including both continuous-wave

and pulse applications. These include radar and broadcast transmitters, x-ray systems, defibrillators,

lasers, and high-voltage semiconductor process equipment applications, where resistors must handle

peak voltage anywhere from 8KV to 75KV.

Typical applications include current limit in capacitor charge/discharge, crowbar, and tube-arc circuits.

In these uses, bulk ceramic resistors provide low inductance, high average power per unit size, stability

at high voltage, and durability at extreme peak-power levels. Film resistors typically cannot withstand

high-voltage pulse applications.

RF/Digital Loads and High-Frequency Applications

Token Non-Inductive Voltage Resistors are used extensively for high-frequency RF loads in broadcast

and communication equipment because of their non-inductive characteristics. They provide excellent

non-inductive power-handling capacity at frequencies up to the gigahertz range, with no sacrifice in

power dissipation.

Film resistors may provide the needed non-inductive characteristics required by such RF applications,

but they have size limitations and present reliability problems due to potential film burnout. This is

especially true in advanced digital applications such as digital radio and TV transmitters involving

pulses at high frequencies.

Application Notes

 Due to the high voltage which can appear between the end cap and any adjacent metal part, resistors should

be mounted at an adequate distance from other conductors.

 An appropriate number of resistors may be screwed together as a stick to provide an assembly which will be

capable to withstanding any desired voltage, providing no individual resistor is subject to a greater stress or

power dissipation than is recommended in its data sheet, and that appropriate anticorona devices are fitted.

 The axial termination should not be bent closer than twice the diameter of the terminal wire from the body of

the resistor.

When resistors are required to be potted, the preferred encapsulant is a silicone compound.

Oil Immersion

For some high voltage applications it is required to immerse the components in oil or gas to reduce the

effects of corona and surface tracking. A special lacquer protected version of the resistor is available,

suitable for immersion in transformer oil or SF6.
