Product Introduction
A Perfect Choice for High Frequency RF Circuit Designs
Features :
Special Oxide Film technology
Applications :
Telecommunication equipment
Speciality product for RF applications
Low-inductance non-helical trimmed product
Lead (Pb)-free and RoHS compliant
Industrial electronics
RY31A specialty MELF Non-Inductive Resistors combines the
advanced pulse load capability and the suitability for RF
applications in a single component.
They are the perfect choice in RF high frequency circuit designs
where the parasitic inductance of regular, helical trimmed
resistors cannot be accepted, but where also pulse energies apply.
Typical applications are in the fields of telecommunication
equipment and industrial electronics.
RY31A - High Frequency Metal Oxide Film Resistor, with the
inner and outer surfaces coated with a special glass, features higher thermal resistance and larger
electric power capacity for the compact volume. Unlike conventional wire wound type, the volumetric
resistance will provide superior stability versus frequency and excellent durability against transient
voltage. RY31A is suitable for the application with large current as well as high frequency circuit.
In very low resistance values, between 1.0 and 100 ohm, these are available in rated wattage 10W,
25W, 50W, 100W, and 150W packages.
The High-Frequency RY31A Series is RoHS compliant and lead free. For customed designs, tighter
tolerances, non-standard technical requirements, or custom special applications, please contact our
Sales Office, or link to Token official website "High Voltage Resistors" to get more information.

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.
