APPLICATION NOTE
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
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
