Bergquist 1000VOUS Series Self-Adhesive Thermal Gap Pad, 0.125in Thick, 1W/m·K, Silicone, 8 x 16 x 0.125in

The Bergquist Ultra Conformable, Thermally Conductive Material for Filling Air Gaps. It is recommended for applications that require a minimum amount of pressure on components. The viscoelastic nature of the material also gives excellent low-stress vibration dampening and shock absorbing characteristics. It is an electrically isolating material, which allows its use in applications requiring isolation between heat sinks and high-voltage, bare leaded devices.
