DS5404-1.0 November 2000
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.
