SIL PAD TSP 1600S

## **Features and Benefits** 

- Thermal impedance: 0.61°C-in[2] /W (@50 psi) 

- Electrically isolating 

- Low mounting pressures 

- Smooth and highly compliant surface 

- General-purpose thermal interface material solution 

The true workhorse of the Sil-Pad product family, Sil-Pad 900S thermally conductive insulation material, is designed for a wide variety of applications requiring high thermal performance and electrical isolation.These applications also typically have low mounting pressures for component clamping. 

Sil-Pad 900S material combines a smooth and highly compliant surface characteristic with high thermal conductivity.These features optimize the thermal resistance properties at low pressures. 

Applications requiring low component clamping forces include discrete semiconductors (TO-220,TO-247 and TO-218) mounted with spring clips. Spring clips assist with quick assembly and apply a limited amount of force to the semiconductor.The smooth surface texture of Sil-Pad 900S minimizes interfacial thermal resistance and maximizes thermal performance.
