Temperature sensors are essential components in a wide array of industries, ranging from automotive, medical technology, chemical industry, and consumer electronics. One type of temperature sensor is the Negative Temperature Coefficient (NTC) thermistor, such as the GT202F1K. This article will provide an overview of the GT202F1K application field and working principle.

NTC Thermistor - Overview

NTC thermistors are temperature-sensitive semiconductor devices that display reduced resistance when exposed to increasing temperatures. Like other thermistors, the GT202F1K is constructed from ceramics and metal oxides, which can conduct electricity and provide an excellent response time to varying temperatures. It is also highly accurate and offers very stable performance.

The size of the chip makes it easy to integrate into even small-scale projects, making it an ideal choice for portable applications. Furthermore, the GT202F1K has a wide operating temperature range from -40°C to 250°C, providing great flexibility for a variety of applications.

GT202F1K - Application Fields and Working Principle

In consumer electronics, the GT202F1K is ideal for temperature measurement in mobile devices and laptops. It is also used in automotive applications, mainly for engine control systems, HVAC systems, and transmission control systems. As well as providing precise temperature readings, the device also offers protection against over-heating and other potentially hazardous temperature faults.

The GT202F1K is a 3-terminal thermistor with 1-2 connected to the heater circuit and 3-4 to the temperature sensor. It operates on a simple principle: When the temperature surrounding the device increases, the thermistor’s resistance drops, allowing more current to flow through the 3-4 terminals. This increases the voltage on the 1-2 terminals, which can then be read by the connected electronic IC circuit.

Additionally, the GT202F1K is designed to be highly accurate in its temperature readings, with an overall accuracy that is better than ±1°C. This makes it an ideal choice for precise applications such as medical technology, research, and manufacturing.

Conclusion

In short, the GT202F1K is an excellent choice for a variety of temperature sensing applications, offering great flexibility, accuracy, and stability. Whether it is used in mobile devices, automotive systems, or medical applications, the GT202F1K provides reliable temperature data that can be trusted.
