The SM202F1K is a negative temperature coefficient (NTC) thermistor, which is a type of temperature sensor. NTC thermistors are sensors designed to measure and regulate temperature. They are typically used in high-temperature applications, such as engine and vehicle controls, and are also used in the medical, automotive, aerospace, and robotics industries.

The SM202F1K operates using the principle of resistance. An NTC thermistor is composed of a semiconductor material that has a negative temperature-resistance coefficient. This means that as the temperature around the device increases, the electrical resistance of the device decreases. This change in resistance is what allows for temperature sensing.

The SM202F1K is a 10K ohm at 25°C thermistor. The resistance of the device decreases as the temperature rises, so when the temperature around the device is higher than 25°C, the resistance is lower than 10K ohm. Conversely, when the temperature is lower than 25°C, the resistance is higher than 10K ohm.

The SM202F1K is designed to provide accurate temperature measurements over a wide temperature range, from -30°C to 125°C. The device is also very small and lightweight, making it ideal for applications where space is limited. Additionally, the device is very reliable and has a long life compared to other temperature sensors.

One of the main applications of the SM202F1K is in automotive applications. The device is often used in air conditioning systems, engine controls, and brake systems. It is also used in medical applications to measure patient body temperature and to regulate the temperature of medical instruments.

The SM202F1K is also used in robotics and aerospace applications, as well as in consumer electronics. The device can be used to regulate the temperature of computers, cellphones, and other consumer devices. It is also often used in scientific instruments, such as thermometers and calorimeters.

In conclusion, the SM202F1K is a 10K ohm NTC thermistor that can accurately measure a wide range of temperatures, from -30°C to 125°C. It is often used in automotive, medical, robotics, aerospace, and consumer electronic applications. The device is small, lightweight, and reliable, making it a popular choice for temperature sensors.
