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.
