Pushpin Attached Heat Sinks (no tabs, no C-bore)

Pushpin Attached Heat Sinks (no tabs, no C-bore)

The following heat sinks feature attachment holes.

Push-pin and spring combinations can be chosen to suit each particular PCB thickness and chip size.

A new series of push pin heat sinks, LCBM / LCBH / UCBM / UCBH, that incorporate integrated counterbores, is now available. The counterbores allow for a greater number of pin/spring combinations to be utilized.
