UPC 00051131289123
Part Number 5549S-15

3M™ Thermally Conductive Silicone Interface Pad 5549S is a highly conformable, slightly tacky silicone elastomer pad. Designed to provide preferential heat transfer path between heat generating components and heat sinks or other cooling devices.

  • Very high thermal conductivity and good electrical insulation properties
  • Good softness and conformability even to non-flat surfaces
  • Thin polymeric film carrier supported on 1 side for good converting and handling properties
  • Slight tack allows pre-assembly
  • Good dielectric properties
  • Good wettability for better thermal conductivity
  • High temperature resistance
  • Tacky both sides
  • Larger sheet size is available

3M™ Thermally Conductive Silicone Interface Pad 5549S has a medium-soft pad that conforms to uneven substrates, providing excellent wettability to fill gaps for improved thermal performance. The "S" supporting layer (permanent film carrier) has a non-tacky surface, providing excellent workability, puncture resistance, and the flexibility to rework materials. 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.




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




Examples:
LED displays
Electric vehicle (EV) batteries
Wireless charging units
Satellite navigation
Sensors
Process control equipment
Test & measurement devices
