Sil Pad

Sil-Pad 900S

Features & Benefits

  • Thermal impedance: 0.61ºC-in2/W (@50 psi)
  • Electrically isolating
  • Low mounting pressures
  • Smooth and highly compliant surface
  • General-purpose thermal interface material solution

Description

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 pressure. 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.

Typical Applications include

  • Power supplies
  • Automotive electronics
  • Motor controls
  • Power semiconductors
