Type CFH Series
The CFH is a high quality range of
aluminium housed power resistors
offering environmental protection to
IP55,
1.8kW power dissipation, and the
ability to absorb electrical pulses of
up to 24kJ.
The use of advanced materials in
the construction of this device
enables operating temperatures of
up to 450ºC giving very high power
density.

... Parasitic Capacity. Parasitic capacity does not depend on the resistance value, but it changes with frequency. The supplied value are just referred to 1 kHz (the higher) and 100 kHz. During normal load conditions the effects of parasitic capacity are negligible. However in the presence of transients of high voltage < ...
