Heatsinks, Pads & Bushings

Aluminum heatsinks for power semiconductors: TO-220, TO-247, TO-3 mounts, rectangular, finned, fan-equipped. Thermal resistance 1-15 °C/W. Insulating pads in mica, silicone (sil-pad), and ceramic AlN. Plastic bushings and washers for electrical isolation of the mounting screw. Filter by transistor package, dimensions, thermal resistance, and insulator type. Used in power supplies, inverters, audio amplifiers, PWM stages — anywhere effective cooling of power switches and regulators is required.
