3M 5550H-05 Thermally Conductive Acrylic Interface Pad

5550H-05

3M™ Thermally Conductive Acrylic Interface Pad 5550H is a highly conformable and ultra-soft pad with high thermal conductivity of 3.0 W/m-K (3M test method). This pad consists of a slightly tacky acrylic elastomeric sheet filled with thermally conductive ceramic particles. It is designed to transfer heat from heat generating components to heat sinks and cooling devices, improving device reliability and extending the component's life.

Very soft but good handling
Good softness and conformability even to non-flat IC surfaces
Incorporates a thin firm acrylic layer for good handling

Color: White / Light Gray

Liner Material: Unwind Side: PET Film, Liner Side: PET Film

Backing/Carrier Material: Acrylic Elastomer Sheet Filled w/ Thermally Conductive Ceramic Filler

TotalThickness: 0.50 mm
