Power NTC Thermistor Load Temperature Characteristics
- Resin coated disk NTC thermistor with uninsulated lead-wires.
- Suitable for both AC and DC circuits up to a voltage of 265 V(rms).
- Excellent mechanical strength.
- Suitable for PCB mounting.
- 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.
- 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.
- 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.
- 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.
- Make sure that thermistor are adequately ventilated to avoid overheating.
- Avoid contamination of the thermistor surface.
- Avoid contact of NTC thermistor with any liquids and solvents. Ensure that no water enters an NTC thermistor.
