Thermistors are temperature-sensing elements made of semiconductor material that has been sintered in order to display large changes in resistance in proportion to small changes in temperature.
his resistance can be measured by using a small and measured direct current, or dc, passed through the thermistor in order to measure the voltage drop produced.
These solid state temperature sensors actually act like electrical resistors that are temperature sensitive. That is where the name, a clear combination of the words thermal and resistor, comes from. Ametherm specializes in NTC, or negative temperature coefficient, thermistors.
Package: bulk packing
Packing tool: by cartons or box
Resistance ratio is a characteristic that identifies the ratio of zero-power resistance of a thermistor at 125° to the resistance at 25°C. Maximum operating temperature is the highest body temperature where the thermistor will operate with acceptable stability for an extensive time period.
This temperature should not surpass the highest value specified. Likewise, maximum power rating for thermistors is the highest power at which a thermistor will operate for a period of time while maintaining stability.
