Advance Technique of Non-Inductive & Serpentine Pattern (HI80)

High Voltage Resistors (HI80) Serpentine Pattern

Non-Inductive Performance:

  1. HI80 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.

  2. 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:

  1. Type High Voltage HI80 Precision Resistors combine Token's Non-Inductive serpentine pattern, high thru-put screen printed silicone coating.

  2. 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.

  3. The cap and lead assemblies are pressed onto the resistor core, finishing the resistor and providing rugged terminal attachment.
