Thermistors are temperature sensing elements made of semiconductor material that has been sintered to show large changes in resistance in proportion to small changes in temperature.
This resistance can be measured using a small, measured direct current, or DC, passed through the thermistor to measure the voltage drop produced. The way the resistance decreases is related to a constant known in the electronics industry as beta, or ß. Beta is measured in °K.
Suitable for a variety of applications, from automotive to industrial and vending.
CHARACTERISTICS:
- Epoxy resin
- Resistance: 0.1 - 500 K Ω
- Small size
- Fast reaction
- High accuracy in measurement
- High long-term stability
- Temperature range: -40°C + 125°C
- Available in standard SMT, THT, or with
custom body and termination probes
PTC Thermistors
PTC thermistors are nonlinear resistors, which alter their resistance characteristics with temperature. The resistance of the PTC increases with increasing temperature.
