The LC300RS thermally conductive EMI absorber pad combines heat dissipation and electromagnetic wave absorption in a single silicone-based material. Like conventional thermal interface materials, it can be installed directly between a heat-generating component and a heat sink, providing a thermal transfer path while absorbing electromagnetic energy to help reduce electromagnetic interference (EMI).
By integrating thermal management and EMI suppression, LC300RS helps simplify mechanical design in space-constrained electronic assemblies. Depending on the application and verified EMI performance, it may reduce or eliminate the need for separate shielding cans, helping reduce component count, assembly complexity, and overall costs.
The soft silicone base conforms to mating surfaces and accommodates dimensional tolerances, helping reduce mechanical stress on components and supporting reliable assembly. LC300RS is suitable for thermal management and EMI suppression in electronic and communication equipment.
