Fast Response Miniature Size SMD NTC Type Thermistor High
Reliability Ceramic Structure
In a smartphone or tablet, multiple SMD thermistors are used for
temperature monitoring, and the basic circuit is a voltage divider
circuit connected in series with NTC thermistors and fixed
resistors. The resistance value of the NTC thermistor installed
near the heat-generating parts such as the CPU and power module
will decrease with the rise of temperature, so the output voltage
of the voltage divider circuit will change, and the change will
protect the circuit components after being sent to the
microcontroller. Affected by overheating.

Negative temperature coefficient thermistor, also known as NTC
thermistor, is a kind of sensor resistance whose resistance value
decreases with the increase of temperature. Widely used in various
electronic components, such as temperature sensors, resettable
fuses and self-adjusting heaters, etc.
