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

Caution
• When force is applied to the lead wire the leg connections may break or chipping may occur.
• May get hot during use. When designing the environment around the power thermistor be especially careful with lead wire connections, materials used in the direct vicinity and the layout of other electrical components.
• Do not use two or more power thermistors in a row.

Inrush Current Limiting Surge Supression Power NTC Thermistor Application Precautions
1) For inrush current limiting, the NTC thermistor must be connected in series with the load circuit. Several inrush current limiters can also be connected in series for higher damping. Inrush current limiters must not be connected in parallel.
2) In general inrush current limiters require time to get back to cold state, in which they can provide adequate inrush current limiting due to their high resistance. The cooling down time depends on ambient conditions.
3) It should be considered that the surrounding area of NTC Thermistor may become quite hot. Ensure the adjacent components are placed at sufficient distance from a thermistor to allow for proper cooling time of the thermistor.
4) Make sure that adjacent materials are designed for operation at temperatures comparable to the surface temperature of the thermistor. Make sure that surrounding parts and materials can withstand this temperature.
5) Make sure that thermistors are adequately ventilated to avoid overheating.
6) Avoid contamination of the thermistor surface.
7) Avoid contact of NTC thermistors with any liquids and solvents. Ensure that no water enters an NTC thermistor.
