Thermal Non-Isolating Pad (TN-48)

The TN-48 thermal non-isolating pad is a composite of .0015” (.038 mm)

aluminum foil coated on both sides with a .0025” (.063 mm) thick thermally

and electrically conductive rubber. These pads have a thermal conductivity of

0.65 W/m-K and a maximum temperature rating of 180°C.

One side of the TN-48 pad is adhesive and may be applied directly to the

IM483 driver. The TN-48 pad eliminates the problems associated with using

thermal grease.

This pad are also included in the heat sink kit.
