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. 2. This efficient non-inductive construction retains performance advantages and heavy load characteristics which is ideal for high frequency applications. Serpentine Pattern Screen Printing Design: 1. Type RI82 Precision High Voltage 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 lead assemblies are pressed onto the resistor core, finishing the resistor and providing rugged terminal attachment.
