Description

Fujipoly Sarcon PG45A-00-200GY thermal interface pad is a high-performance gap filler designed to improve heat transfer between electronic components and heat sinks. Manufactured by Fujipoly, this silicone-based thermal interface features a putty-like structure that easily conforms to uneven surfaces and varying component heights. With a thermal conductivity of approximately 4.5 W/m-K, the PG45A series efficiently fills air gaps that would otherwise trap heat, helping maintain optimal operating temperatures in demanding electronic assemblies.

Engineered with an extremely low compression force, the PG45A material can compress by up to 70-90%, making it ideal for delicate circuit boards or assemblies with components of different heights. This flexibility reduces mechanical stress during installation while ensuring reliable contact between heat-generating devices and cooling solutions. Designed to operate in environments ranging from -40°C to +150°C, the PG45A-00-200GY pad provides dependable thermal management for modern electronics and high-power devices.
