- Electrical-Insulation Thermal Interface
- Compliant Fiberglass-Reinforced Low-Pressure Thermal Pad
Product Description
BERGQUIST® SIL PAD® TSP 1600S is a fiberglass-reinforced, silicone-based thermal interface pad developed for electrically insulating heat transfer in low-pressure clamping applications. The pink, 0.229 mm thick material combines a smooth, compliant surface with a thermal conductivity of 1.6 W/m·K and a thermal impedance of 0.61 °C·in²/W at 50 psi, measured using ASTM D5470. It supports an operating temperature range of -60 to 180 °C and is available in sheet, roll, and die-cut formats, with or without pressure-sensitive adhesive.
Key features
- Low-pressure thermal performance: Provides a typical thermal impedance of 0.61 °C·in²/W at 50 psi using ASTM D5470.
- Electrical insulation: Delivers a typical dielectric breakdown voltage of 5,500 Vac using ASTM D149.
- Flexible supply formats: Available as sheets, rolls, and die-cut parts, with or without pressure-sensitive adhesive.
Applications / Suitable for
- Power supplies
- Automotive electronics
- Motor controls
- Power semiconductors
- Discrete semiconductors mounted with spring clips under low clamping force
