Detailed Product Description

Excellenthumidity Resistance SMD Varistor Small Size RoSH Compliant
 

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.
 

Temperature monitoring during mobile device battery charging
 

In battery packs (lithium-ion batteries) of mobile devices such as smartphones, there are terminals for temperature monitoring in addition to + terminals and - terminals, and SMD thermistors are mounted inside them. When the battery temperature rises, the temperature of the NTC thermistor will also rise, and the resistance value will drop. When the charging temperature exceeds the upper limit, the charging control IC will stop charging. A protection IC within the battery pack measures the battery voltage to prevent overcharging or overdischarging. In situations such as fast charging that require more precise charging control, an NTC thermistor is required to be connected to the charging control IC to measure the ambient temperature.
