Serpentine Pattern Design Achieves
High Power Voltage (RI80)
Preview
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.

RI80 Non-Inductive & Serpentine Pattern - Advance Technique
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
neutralizationof 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 RI80 Precision High Voltage 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.
