The CP series also provides maximum heat removal for SCRs, rectifiers, diodes, thyristors, and other high-power semicon- ductor devices. The CP series is customizable to fit multiple applications. Length and mounting hole pat- terns can be specified.

FeatureS
- Designed for Ohmite products, Pre drilled hole pat- terns for standard Ohmite planar resistors TAP600/ TAP800 and TAP1K0/TAP2K0.
- Design flexibility, Chill Plate lengths can be config- ured as well as mounting hole patterns to accept a multitude of devices.
- Thermal efficient design, Exposed copper tubing on the mounting surface for the most efficient heat transfer.
