Extruded Heat Sink

An extruded heat sink enhances heat transfer from high-power semiconductor devices, lowering external case and internal junction temperatures for optimal performance and reliability. It is essential for various devices, including RF power transistors and IGBTs, and is crucial in power conversion applications. These heat sinks are utilized across numerous industries such as renewable energy, automotive, and telecommunications. When choosing a heat sink, consider dimensions, thermal resistance, and extrusion shape for the best price-performance ratio. Richardson RFPD offers the support to help you address any thermal management challenges you face to ensure the highest performance of your power conversion system and the longest life of the components in your design.
