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.

PERFORMANCE
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 Heat Sink selection.
It is recommended that the effectiveness of any heatsink
is confirmed in the specific operating environment in
which it will be subjected
SAFETY
In some circumstances
exposed Heat Sink surfaces may become very hot. Contact
with these surfaces may cause burns damage to skin.
INSTALLATION
NOTCHES
For Heat Sink lengths up to 87.5mm one single
notch in each flange centrally along its length.
For
Heat Sink lengths from 88mm to 150mm three notches in
each flange 38mm apart.
STANDARD
NOTCH DIMENSIONS
STUDS
AND SOLDERABLE PINS
Some heatsink's have standard
solderable pins for flow soldering to circuit boards.
Non standard pins and studs can also be fitted.
CLIPS
A full range of standard clips
are available from stock.
