Heatsinks

These tiny heatsinks measure just 11mm square and 5mm high. They are finished in black anodising for good heat radiation and come with thermal tape already applied, so just peel and stick. These are...

These tiny heatsinks measure 13mm wide, 18mm long and 6mm high. They have a 13mm x 13mm square heatsink surface which has thermal tape already applied. Originally designed for cooling RAM chips in...

These great little heatsinks measure 20mm diameter and 15mm high and have a 12mm diameter solid centre section. They are perfect for adding heatsinking to LEDs of up to a couple of watts, more if you...

These great little heatsinks measure 20mm diameter and 20mm high and have a 5.5mm diameter hole through the centre. They are perfect for adding heatsinking to LEDs of up to a couple of watts, more if...

These are nice little heatsinks that measure 28 x 28mm and 11mm high. They are ideal for cooling power LEDs up to a couple of watts, or more if you use a fan as well. They come complete with thermal...

Nice circular fan-style heatsinks for cooling LEDs up to 3W or so. They measure 36mm diameter by 22mm thick and have a black finish. Centre solid section is around 15mm diameter. Note that it's...

These are nice little heatsinks that measure 40 x 40mm and 10mm high. They are ideal for cooling power LEDs up to a couple of watts, or more if you use a fan as well. They come complete with thermal...

Nice circular pin array style heatsinks for cooling LEDs up to 10W or so. They measure 51mm diameter by 36mm thick and have a black finish. Centre solid section is recessed 2.3mm and is 45mm...

These are nice little heatsinks that measure 53mm diameter x 20mm thick. They are ideal for cooling power LEDs up to 5 watts, or more if you use a fan as well. They are designed to allow you to...

These tiny heatsinks measure just 8.8mm square and 5mm high. They are finished in black anodising for good heat radiation and come with thermal tape already applied, so just peel and stick. These are...

These heatsinks measure 50mm x 25mm x 10mm. They are designed for the LM2596 power modules elsewhere on this site but are also suitable for cooling LEDs of course. One of these will handle around 2-3...

This is a large heatsink ideal for cooling high powered LEDs. It is 90mm diameter and 10mm thick. It has a 35mm diameter solid centre section which is predrilled and tapped for both 20mm star LEDs...

This is a large heatsink ideal for cooling high powered LEDs. It is 90mm diameter and 25.4mm thick. It has a 35mm diameter solid centre section which is predrilled and tapped for both 20mm star LEDs...

These heatsinks measure 30(H) x 35(W) x 25(L)mm. They are black anodised aluminium for good heat radiation and are rated at 10°C/W. These are ideal where a bit of extra cooling is needed, such as...
