For inrush current limiting, the NTC must be connected in series with the load circuit and several limiters can also be connected in series for higher damping.
Inrush current limiters must not be connected in parallel since the NTC thermistor with the smallest rated resistance consumes almost the entire current in the circuit and the resulting overload could destroy the component.
In general, inrush current limiters need time to return to their cold state in which they can provide adequate inrush current limiting due to their high resistance and as expected, the cool-down time depends on the ambient conditions.
