Compact TO-220 heatsink kit

This pack contains twenty anodised aluminium heatsinks measuring 19 x 15 x 10 mm with a 0.8 mm fin thickness and an M3 mounting hole. They are designed to fit TO-220 packaged devices such as L7805 and LM337 regulators as well as MOS transistors and similar IC chipsets. The black finish aids radiative cooling in hobby and repair projects.

Suited for discrete component cooling

Builders fitting individual voltage regulators, driver transistors or similar through-hole packages will find the dimensions match the TO-220 footprint. The kit is not intended for CPU or GPU cooling, nor for surface-mount devices that lack the required mounting tab and hole spacing. Buyers needing higher thermal capacity or forced-air integration should look at larger extrusion profiles.

Fits into prototype and repair builds

Each heatsink weighs roughly two grams and adds minimal height, leaving clearance for adjacent board components. The M3 hole allows direct bolting to the device tab or to a PCB mounting point without additional brackets. The twenty-piece quantity supports batch assembly or spares for multiple repair jobs.

Questions about this item

What mounting hardware do I need to attach these 19x15x10mm heatsinks to a TO-220 package?

Each heatsink has an M3 screw hole; you will need M3 screws and matching nuts or standoffs to secure it to the component.

Can these aluminium heatsinks be used on older L7805 or LM337 regulators that I already have on a board?

Yes, they are designed for TO-220 packages including L7805 and LM337 regulators, so they fit those existing components directly.

How can I verify the heatsinks are dissipating heat properly after installation?

Power the circuit and check that the TO-220 device stays within its thermal limits; the anodised black aluminium should feel warm but not excessively hot.
