Type CBT Series
The CBT series of resistors is
constructed utilising solid carbon
composition, which is the traditional
medium for absorbing high energy
pulses, in cases of high inrush current.
These resistors have evolved over
many years to have excellent pulse
withstand capabilities, whilst remaining
very
characteristics have been achieved by
prudent selection of materials of
optimum physical properties and
by advances in the manufacturing
process.
