Power Resistor Materials Construction
In order to meet the demands of multiple applications, Ohmite produces its market leading resistors in multiple power resistor material constructions. Wirewound, Composition, Thick Film, and Thin film are just a few of the popular constructions offered by Ohmite.
- Wirewound: Good stability and high-temperature performance.
- Composition: High energy and pulse handling.
- Thick Film: High values and high voltage performance.
- Thin Film: high-value stability and tight tolerance.
Composition
What is a Composition Resistor? Composition resistors are produced using a mixture of a finely ground insulator and conductor. This mixture is then compressed into a cylindrical shape.
