Heat Dissipation:

Although the use of proprietary heat sinks with lower thermal

resistance is acceptable, up rating is not recommended. The use

of proprietary heat sink compound to improve

thermal conductivity is essential.

The CJR range of power resistors

are aluminium housed and wire

wound, designed to withstand high

adiabatic pulses in a compact

package. These devices offer a

high power dissipation capacity

with the appropriate heat sink and

superior environmental protection

(IP64). The product is silicone free

for specific use on assembly cells

within the automotive assembly

industry.
