EXTRUDED HEAT SINKS FOR POWER SEMICONDUCTORS

490 SERIES

King Size Heat Sinks for High-Power Rectifiers

The 490 Series can be used to mount a single high-power rectifier or a grouping of smaller

power devices. The semiconductor device mounting surface is free of anodize on the entire

surface on one side only; finish overall is black anodize. Use Type 109 mounting brackets

(see accessories section) for mounting to enclosure wall and for electrical isolation. The

anodize-free mounting surface is milled for maximum contact area. The 490 Series Can also

be drilled for mounting and cooling IGBTs and other isolated power modules. Material:

Aluminum Alloy, Black Anodized.
