High Reliability Ceramic Structure SMD Varistor Small Size For Semiconductor Protecting
SMD chip NTC thermistor has the characteristics of small size, high reliability ceramic structure, fast response, good heat cycle resistance, etc., and is widely used in lithium batteries, hybrid design multi-function modules, IT equipment, etc. Because the SMD chip NTC thermistor is suitable for leadless high-density surface mount, it plays the role of temperature monitoring and overheating protection in the following products:
Temperature monitoring of smartphones and tablets
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.
