Grid & Ribbon Resistors
Crohm Series CG grid and CH high-current resistors are an industry leader for quality construction and dependability, featuring stainless elements and heavy-gauge stainless-steel terminals on double-insulated metal frames. Elements use either offset grids or continuous ribbons, welded for an uninterrupted current path that avoids spacer-related issues. Assemblies use high-temperature silicon-bonded mica insulation for demanding applications.
