Compact Heat Sinks for TO-220 Components

This pack supplies twenty aluminium heat sinks sized 25 by 15 by 10 millimetres for TO-220 transistors and similar packages. The parts arrive without mounting pins so you can choose your own fastening method. They suit hobbyists and repair technicians who need to dissipate heat from discrete power devices in small enclosures.

Steady-State Thermal Behaviour

Under continuous load the aluminium body spreads heat across its finned surface and relies on natural convection or case airflow to maintain a stable temperature. Without forced air the sink reaches equilibrium more slowly than an active cooler, so sustained high-wattage dissipation will need additional ventilation. The bare-metal finish offers no insulation, so electrical clearance must be managed during installation.

Questions about this item

Do these heat sinks generate any noise or heat during continuous operation?

The aluminium heat sinks have no moving parts, so they produce zero noise and add no heat of their own; they simply draw thermal energy away from the attached TO-220 device.

What else must I already own to mount these 25 × 15 × 10 mm heat sinks on a TO-220 transistor?

You need a TO-220 component, thermal paste or a thermal pad, and a mounting method such as a screw, clip or adhesive because the heat sinks are supplied without pins.
