Application Guide for NTC Thermistors

Applied voltage and currents generate heat. As temperature changes, resistance will change as well. Thermistors function as both a thermo-sensitive device and a heating element. They play an active role in many different applications (temperature sensors, temperature compensation, circuit protection). Thermistors are available in different shapes and characteristics to fit the needs of modern electronics, such as smartphones, wearable terminals, and automotive devices.Thermistors

Have you ever held an electronic device, like a cell phone, that felt hot to the touch? As smartphones become smaller and more advanced, they run the risk of overheating. Thermistors are used to detect heat inside phones, and then they relay that information to an IC.

Inside a phone, a thermistor will:

Many other electronic devices benefit from NTC thermistors because of the many benefits they offer.

Electronic thermometers are found in most residential homes. When people are feeling sick, this is one of the first tools they grab. These electronic devices measure human temperature using thermistors.

Vacuum cleaners utilize nozzles that are equipped with a motor. It is not uncommon to for the motor to stop while vacuuming a carpet. This problem will send a large current to the motor. Thermistors are used to prevent machines from breaking as a result of a high-current influx.

Thermistors are also commonly found in:

Choosing the correct thermistor types for your specific application can be challenging to decide without professional help. Our talented team is standing by to help you work through your product application and design needs so that you get the ideal thermistors. Using the wrong thermistor could be detrimental for the electronic devices you are building.
