Sil-Pad

A2000

Higher Performance, High Reliability Insulator

Features and Benefits

• Thermal impedance:

0.32°C-in2/W (@50 psi)

• Optimal heat tr ansfer

• High thermal conductivity: 3.0 W/m-K

Sil-Pad A2000 is a confor mable elastomer

with very high ther mal conductivity that acts

as a ther mal interface between electrical

components and heat sinks. Sil-Pad A2000 is

for applications where optimal heat transfer is

a requirement.

This thermally conductive silicone elastomer is

formulated to maximize the thermal and

dielectr ic performance of the filler/binder

matr ix.The result is a grease-free , con-

fo rmab le material capable of meeting or

exceeding the ther mal and electrical require-

ments of high reliability electronic packaging

applications.

Typical Applications Include:

• Motor drive controls

• A vionics

• High-voltage power supplies

• Power transistor / heat sink interface

Configurations Available:

• Sheet form, die-cut parts and roll for m

• With or without pressure sensitive adhesive
