Introduction
Power Thermistors, also known as Inrush Current Suppressors, are a sub-category of NTC (Negative Temperature Coefficient) thermistors. Power Thermistors utilize the self heating properties of NTC thermistors which self heat with current flow, dramatically decreasing resistance.
Power thermistors utilize the characteristics of NTC thermistors where a device heats up when current flows through it, and this self heating causes a dramatic decrease in resistance. Aolittel’s power thermistors are less expensive compared to conventional power thermistors, due to lower manufacturing costs achieved
