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

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

meet

customer

requirements including Faston,

terminals, butt splices etc.
