surge gard inrush current limiters are special power ntc thermistors which are connected in series with the load.
· high hot to cold resistance ratio
· 0.3a - 30a
as a result of current flow the thermistor heats reducing it””s value and thus limiting damaging surge currents to the load.surge currents which occur when electrical circuits are switched on can cause serious damage to sensitive electronic components which may exceed their rated values unless the surge is controlled. damaging surges may be prevented by using surge-gard inrush current limiters.
