GENER AL INFORMATION

Aluminium Alloy to BS1474 6063, T6.

For heatsink lengths up to 87.5mm one single notch in

each flange centrally along its length.

For heatsink lengths from 88mm to 150mm three

notches in each flange 38mm apart.

Some heatsinks have standard solderable pins for flow

soldering to circuit boards. Non standard pins and

studs can also be fitted.

A full range of standard clips are available from stock.

Profile Tolerances: All profile dimensions are toleranced

within BS1474 and this should be taken into

consideration when designing our profiles into your

equipment. Further details of specific tolerances can be

supplied if required.

Length Tolerances: +/- 0.4mm

Tighter Tolerances can be offered if required.

Performance figures given are for natural convection

operating conditions and are for a 60ºC temperature

rise with a centrally mounted heat source and vertically

mounted fins. Under general operating conditions the

thermal mounting arrangement of devices is not known

and therefore the figures should be used only as a

guide to heatsink selection.

It is recommended that the effectiveness of any

heatsink is confirmed in the specific operating

environment in which it will be subjected

In some circumstances exposed heatsink surfaces

may become very hot. Contact with these surfaces

may cause burns damage to skin.
