TIR300L-A1 — Product overview
TIR®300L-A1 series is a graphite-enhanced composite thermal interface material engineered for high thermal conductivity and reliable heat dissipation. Reinforced with an aluminum foil layer, it maintains structural integrity throughout handling and application. The material conforms well to a variety of surfaces, enabling efficient thermal contact and ease of assembly. It is ideally suited for use between power transistors and heat sinks, as well as in large-area thermal interface applications.
