Inrush Current Limiters
(ICL)
Many items of equipment like switch-mode power
supplies, electric motors or transformers exhibit excessive
inrush currents when they are turned on. The thermistor
limits the current at turn-on by its relatively high cold
resistance. As a result of the load current the thermistor
heats up and reduces its resistance.

ICLs are able to effectively handle higher inrush currents
than fixed resistors with the same power consumption.
They thus provide protection from undesirably high inrush
currents at switch-on and offers a fairly low resistance
during continuous operation.
