Thermistors, like RTDs, are thermally sensitive semiconductors whose resistance varies with temperature. Thermistors are manufactured from metal oxide semiconductor material encapsulated in a glass or epoxy bead. Also, thermistors typically have much higher nominal resistance values than RTDs (anywhere from 2,000 to 10,000 ?) and can be used for lower currents.

APPLICATIONS
AUTOMOTIVE APPLICATIONS
NTC temperature sensors are widely used in motor vehicles.
For example:
• Inlet air-temperature control
• Transmission oil temperature control
• Engine temperature control
• Airco systems
• Airbag electronic systems
• Temperature detection of laser diode in CD players for
cars
• Frost sensors
• ABS
• BMS / charge plugs protection
DOMESTIC APPLIANCES
NTC temperature sensors are in virtually all equipment in the
home where temperature plays a role. This includes:
• Fridges and freezers
• Cookers and deep-fat fryers
• Washing machines and dish washers
• Central-heating systems
• Air conditioning
INDUSTRIAL, TELECOMMUNICATIONS, CONSUMER
In switching, measuring and detection systems
• Process control
• Heating and ventilation
• Air conditioning
• Fire alarms
• Temperature protection in battery management / charging
systems
• LCD contrast control in flat-panel displays, mobile phones
and camcorders
• Temperature compensation of quartz oscillator frequency
in, for example, mobile phones
• Ink-jet printer head temperature detection
• Video and audio equipment
• LED control circuits
