SP205A-30 Phase Change Thermal pad 3.0W/mK
SP205A-30 3.0 W/m·K Phase Change Thermal Pads are solid at room temperature and feature self-adhesive properties for easy handling. When the temperature reaches the phase change range of 45–55℃, the pads soften and transition to a liquid state.
Delivering wet-out performance comparable to thermal paste, they effectively fill gaps between heat sinks and electronic components. Custom die-cut into any shape per customer requirements, these pads offer convenience, high reliability, and straightforward application
