The current range of heatsinks is illustrated with a brief
resumé of their characteristics. The products available are
intended for use with all our power semiconductors - from
the small stud base through to large disc devices and
modules.

All heatsinks are suitable for Natural Air Cooling (AN) and
Forced Air Cooling (FC). In addition to a vast experience of
AN and FC cooling methods we also have many years
experience in liquid and phase change cooling.
A range of coolers for 17mm to 100mm silicon diameter
devices is available, as is a range of associated clamps.

Notes:
1.Thermal ratings are given per
heatsink.
2.Comprehensive data is available
for all our heatsinks to support all
design applications.
3.Black anodising is available on all
air cooled heatsinks for surface
protection and enhanced
performance.
