Thick Film
High Voltage Resistors
An Excellent Solution for The Voltage Trend
in Power Impulse Products
Preview
The High Voltage RI82 Precision Series provides an excellent
solution for design engineers looking for a compact product
with high-voltage capabilities to enable them to design within
the voltage trend for power impulse products.
The RI82 resistors use Token’s proprietary thick film Metal
Glaze resistive element and Serpentine Pattern Design which
provides ideal cost efficient, stability, precision,
non-Inductive, and high voltage characteristics for a wide
range of measurement, voltage divider circuits, and control
functions in high voltage power electronics applications.
By utilizing specific 96 % pure alumina materials with optimum processing, Token are able to control, very
tightly in manufacturing, the important ultra-stable performance tolerance F(±1%), G(±2%), J(±5%), K(±10%),
and M(±20%). Voltage handle up to 30 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 RI82 resistors will improve
the performance of your high voltage system in precision.
The Precision RI82 High 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.
