Part Number 5578H-05

3M™ Thermally Conductive Acrylic Interface Pad 5578H-05 is designed to provide a preferential heat transfer path between heat generating components like integrated circuit chip and heat spreaders and LED lighting.

  • No silicone is used, siloxane gas which often causes electric connection failure can not be generated
  • Good softness and conformability even to non-flat IC surfaces
  • Incorporates a thin acrylic layer for good handling
  • Good thermal conductivity, good heat resistance and good electrical insulation properties
  • Slight tack allows pre-assembly
  • Good wettability for better thermal conductivity

3M™ Thermally Conductive Acrylic Interface Pad 5578H has a medium-soft pad that conforms to uneven substrates, providing excellent wettability to fill gaps for improved thermal performance. This pad performs well in high temperatures, maintaining its thermal conductivity and softness up to 130℃. The thin, firm, low-tack layer provides easy handling for pre-assembly and die-cutting. This pad provides robust thermal management for applications in a variety of market segments, such as consumer electronics, automotive, LED lighting, medical devices, communication infrastructure, and aerospace & defense.

Our family of 3M™ Thermally Conductive Acrylic Interface Pads provide low-outgassing and high-performance solutions compared to silicone. These acrylic pads have no siloxane VOC or oil bleeding, which are associated with silicone products and can often cause device failure. They are lightweight, making them ideal for applications with finer spacing requirements and a small footprint. 3M™ Thermally Conductive Acrylic Interface Pads have good electrical insulation properties to protect against electrical interference and device breakdown.

Recommended Applications:
Heat transfer between PCB and heat sink
Decrease of compression stress to electronic parts by thermal pad softness
Gap filling in electronic devices
Chip on film (COF) heat dissipation
Power electronic component thermal management

LED displays
Electric vehicle (EV) batteries
Wireless charging units
Satellite navigation
