The type RI80 precision high voltage resistors were specifically designed for general purpose high voltage

systems in industrial.

The RI80 uses Token’s proprietary thick film Metal Glaze resistive element and Serpentine Pattern Design which

provides ideal cost efficient, stability, precision and high voltage characteristics for a wide range of measurement,

voltage divider circuits, and control functions in high voltage power electronics applications.

Token RI80 Precision Voltage Resistors are able to absorb large amounts of energy at high voltage while

remaining non-inductive and heavy load characteristics. The RI80 conforms to the RoHS directives and Lead-

free. Customed design, and tighter tolerances are available on request.

By utilizing specific ceramic core materials with optimum processing, Token are able to control, very tightly

in manufacturing, the important ultra-stable performance parameters in operating temperatures from -55°C to

+70°C.

Voltage handle up to 35 KV. This unique process is offered in specific resistance values in a wide variety of sizes

and terminations. The extraordinary operating stability of the Type RI80 resistors will improve the performance

of your high voltage system.

The RI80 Precision Voltage Series is RoHS compliant and lead free. For customed designs, tighter tolerances,

non-standard technical requirements, or custom special applications, please contact our sales for more

information.
