Temperature sensors have many application fields and can be broadly divided into non-contact temperature sensors and contact temperature sensors. Non-contact temperature sensors include bimetallic thermometers, infrared thermometers, thermoelectric couple thermometers and thermal imaging cameras. Contact temperature sensors mostly comprise thermistors, resistance temperature detectors (RTDs) and thermocouples. Among those various categories of temperature sensors, NTC thermistors are commonly used, and NTCS0402E3683HHT is one of the most common types.

NTCS0402E3683HHT is a kind of negative temperature coefficient (NTC) thermistors. It is a two-terminal device with a resistance that falls as temperature rises, thus often serving as a temperature-sensing element. The NTC thermistor have neither semiconductor property nor any active elements, making it a passive device. It is relatively small and thus easy to mount, which makes them popular in applications like temperature controllers. Moreover, NTC thermistors usually have a low thermal mass, so they can adapt to fast changing temperatures quite quickly. This kind of thermistors has a wide range of temperature responses and is also quite cost-effective.

The NTCS0402E3683HHT has a wide application field. They are typically used in various temperature-sensing applications, including medical thermometers, circuit protection devices, HVAC systems, process control systems, air conditioners, and automotive temperature-sensing devices. Furthermore, they can also be used for controlling the temperature in electrical devices, such as battery-charging systems, and for controlling light, either by dimming or turning on and off. In addition, they are also employed in industrial fields to measure furnace temperature, monitor temperature during welding operations, and for other high-temperature applications.

In general, NTC thermistors have a nonlinear resistance-temperature relationship, and the characteristics of NTCS0402E3683HHT also follow the general mathematical formula of an NTC thermistor. However, it should be noted that its resistance-tempearture curve is slightly different from that of other NTC thermistors. NTCS0402E3683HHT has a resistance down to 80 Ohms at -30°C and a tereisitance of approximately 35 Ohms at 25°C, which is that of the ordinary NTC thermistors. The feature of self-heating is also present in the NTCS0402E3683HHT, meaning that the device itself can heat up due to the current passing through it.

To summarize, NTCS0402E3683HHT is a type of negative temperatre coefficient thermistors widely used in many temperature sensing applications. Its small size and physical properties make it a popular choice, and its resistance-temperature curve is slightly different from others. It can accurately measure temperature at various ranges and with the feature of self-heating that enables it to maintain stability over time.
