L37-3 is a silicone based thermal interface pad which offers a good combination of high dielectric breakdown voltage, compliance and low thermal impedance. It contains a fibreglass mesh for enhanced ease of manufacture and is available in various formats such as standard sheets, log-rolls and custom die cut parts. L37-3 is available in a range of thicknesses and with one or two side thermally conductive adhesive pre-applied.
FEATURES
- Base materials are silicone with fibreglass
- One side with natural tack and another side with smooth surface
- Won’t be deformed when being pulled
- High dielectric breakdown voltage
APPLICATIONS
- Electronic components: IC, CPU, MOS
- LED, M/B, P/S, Heat Sink
- LCD TV, Notebook PC, PC Telecom Device, Wireless Hub, etc.
- DDR II Module, DVD Applications, Hand-set applications, etc.
