NTE's THERMO-PADS do away with the old
fashioned mica wafer and conductive grease
method of mounting power semiconductors.
These thermally conductive insulators offer
low heat transfer resistance while still provid‐
ing high electrical isolation between the parts
of the assembly. The elastomeric material
combines the electrical isolation of rigid insu‐
lators with the ability to conform to rough sur‐
faces and reduce contact resistance in much
the same manner as thermal greases. Proper
selection and use of these THERMO-PADS
results in a securely-mounted power semi‐
conductor and minimum resistance to the
heat transfer between it and the heat sink.
Note: NTE425 is a self-adhesive, thermal interface pad for
use in computer applications. For additional information, refer
to page 1-356.
