Additional InformationTO-220 SIL-PAD® Heatsink Insulator
Sil-Pad® is a thermally-conductive interface material developed for the electronics industry. This flexible silicone material is designed to conduct heat away from discrete components or circuit board assemblies into a heat sink, heat spreader, or equipment chassis.
Sil-Pad® 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 Sil-Pad® 400 is to electrically isolate power sources from heat sinks.
Sil-Pad® has excellent mechanical and physical characteristics. Surfaces are pliable and allow complete surface contact with excellent heat dissipation. Sil-Pad® actually improves its thermal resistance with age. The reinforcing fiberglass provides excellent cut-through resistance. Sil-Pad® 400 is non-toxic and resists damage from cleaning agents.
