 Advance Technique

Advance Technique of Non-Inductive & Serpentine Pattern (RI80)

Non-Inductive Performance:

RI80 Non-Inductive Design which uses a serpentine resistive pattern

that offers for zigzagging lines to carry current in opposite directions,

thereby achieving maximum neutralization of flux fields over the

entire length of the resistor.

This efficient non-inductive construction without derating of any

performance advantages is ideal for applications where high

frequency is required.

Serpentine Pattern Screen Printing Design:

Type High Voltage RI80 Precision Resistors combine Token's Non-Inductive serpentine pattern, high

thru-put screen printed silicone coating.

The alignment of the gap in the serpentine resistor pattern with the gap in the coating pattern provides a

complete encapsulation of the resistor element.

The cap and lead assemblies are pressed onto the resistor core, finishing the resistor and providing rugged

terminal attachment.

 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.
