Thermal Sensors Moxie®

NTC & PTC Thermistors

Thermal Sensor MOXIE®
Moxies are a family of, variable resistance thermal sensors having a highly specific “transition region.” Within this transition region the devices typically exhibit a negative temperature coefficient ranging from 40% per °C to 200% per °C. Below the transition region they exhibit a linear “thermistor” characteristic of -2 to -4%/°C.

Applications

Sensors for temperature protection, control and limiting. Voltage, current and frequency limiters in electronics.
Examples: Overtemperature protector for power semi-conductors, such as transistors, power output stages, amplifiers.

1 Sensitivity is defined as the percentage of resistance change per variation of 1†C in temperature.
2 Latching current is the smallest current that will cause the device to make changes in resistance while it’s cooling to a lower temp.
