Description

BERGQUIST SIL PAD TSP 900

FEATURES AND BENEFITS

- Thermal impedance: 1.13ºC-in2 /W @ 50 psi
- Original Sil-Pad material
- Excellent mechanical and physical characteristics
- Flame retardant

TYPICAL APPLICATIONS

- Power supplies
- Automotive electronics
- Power semiconductors
- Motor controls

BERGQUIST SIL PAD TSP 900 is a composite of silicone rubber and fiberglass. The material is flame retardant and is specially formulated for use as a thermally conductive insulator. The primary use for BERGQUIST SIL PAD TSP 900 is to electrically isolate power sources from heat sinks.
BERGQUIST SIL PAD TSP 900 has excellent mechanical and physical characteristics. Surfaces are pliable and allow complete surface contact with excellent heat dissipation. BERGQUIST SIL PAD TSP 900 actually improves its thermal resistance with age. The reinforcing fiberglass provides excellent cut-through resistance. In addition, BERGQUIST SIL PAD TSP 900 is non-toxic and resists damage from cleaning agents.
