A thermistor is made of semiconductor ceramics whose resistance changes depending on temperatures. Thermistors include a positive temperature coefficient (PTC) thermistor whose resistance increases as temperature increases, and a negative temperature coefficient (NTC) thermistor whose resistance, contrary to th...
Re: Inrush current limiting, PTC or NTC? « Reply #51 on: November 24, 2020, 11:36:43 am » reyntjensm, it may be best if you elaborate on your power supply. Is your mains actually 230V, and is their a nominal range that you see or need to cope with? Is the load really...
