Ten silver aluminium TO-220 heatsinks, rectangular finned blocks

Ruth's sister

Ruth's sister 10pcs TO-220 Aluminium Heatsink 19*15*10MM internal power cable

SKU CH-469P-6HA0W

Set of ten aluminium heatsinks measuring 19 x 15 x 10 mm for TO-220 transistors

  • 10-piece pack covers multiple TO-220 devices
  • Aluminium alloy conducts heat away from components
  • 19 x 15 x 10 mm profile fits tight spaces
  • Designed for 7805 and 781 regulator footprints
  • No certification claims — simple, reliable cooling hardware

Pack of 10 TO-220 heatsinks

This pack contains ten aluminium-alloy heatsinks sized at 19 by 15 by 10 millimetres. Each unit is designed to fit TO-220 transistors such as 7805 or 781 regulators. The profile acts as a simple radiator for low-to-medium power dissipation.

Suits hobbyists and repair jobs

The parts suit hobbyists, students or technicians who need a small, low-cost cooler for through-hole linear regulators. They are not suited to surface-mount packages, high-current switching devices or any application that demands a larger thermal mass or forced-air cooling.

TO-220 mounting compatibility

The critical specification is the TO-220 mounting footprint; the heatsink tabs align with the standard tab hole spacing of that package. If your device uses a different outline, these heatsinks will not attach securely.

Questions about this item

Which transistor package do these 19×15×10 mm aluminium heatsinks fit?

They are made for TO-220 transistors such as the 7805 or 781 regulators.

Can I use them on the older TO-220 devices I already have in stock?

Yes, every heatsink in the 10-piece set matches the standard TO-220 footprint.

How do I confirm each heatsink is seated correctly after mounting?

The 19 mm by 15 mm base should sit flat on the transistor tab with no visible gap.
