Power thermistors utilize the self heating characteristic of NTC thermistors which causes a significant decrease in resistance in a short time.
Power thermistors can be used instead of inrush current limiting resistors. Power thermistors have the advantage that their resistance
decreases through self heating which reduces power loss and results in energy savings.
UL1434 File No. E92669 (1D2-22 excluded) certified.

• 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.
