TRANSISTOR MOUNT KIT (P/N 4725) - New Surplus

Part 4725 is a transistor mount kit for securing power semiconductors to heat sinks in aircraft avionics and power electronics assemblies. The kit includes insulating hardware and interface materials that provide mechanical support while maintaining electrical isolation between the component and heat sink. Installation requires proper torque application and alignment per the component manual or CMM to ensure adequate electrical clearance.

Suitable for mounting voltage regulators and transistors in thermal management applications where vibration isolation and electrical safety are critical.
