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.
Tyco Electronics is the leading
European supplier of standard and
custom designed mineral insulated
resistors
for
general-purpose,
drives and controls.
The CJS is a mineral filled power
resistor
in
durable
aluminium
housing offering high performance
as a braking resistor for large
drives.
The high overload rating enables
the absorption of high-energy
pulses with a compact device.
A variety of terminations are
available
to
meet
customer
requirements including Faston,
terminals, butt splices etc.
