(RI82) Advance Non-Inductive Technique & Serpentine Pattern
Non-Inductive Performance:
- Token's RI82 Non-Inductive Design which uses a serpentine resistive pattern that offers for zigzagging lines to carry current in opposite directions, thereby neutralizing maximum of flux fields over the entire length of the resistor.
- This efficient non-inductive construction retains performance advantages and heavy load characteristics which is ideal for high frequency applications.
Serpentine Pattern Screen Printing Design:
- Type RI82 High Voltage Impulse 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 lead assemblies are pressed onto the resistor core, finishing the resistor and providing rugged terminal attachment.
