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 CJB 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 heatsink and
superior environmental protection
(IP64).
Tyco can test resistors to conform
to relevant international MIL and
customer specifications and will
advise on the use of resistors for
pulse applications.
