Temperature sensors are devices that measure the temperature of an object or surroundings. NTC thermistors, short for Negative Temperature Coefficient (thermistors), are resistors whose electrical resistance changes with temperature. NTCLE201E3C90028 is one type of NTC thermistor. It has wide applications and works through a well-known principle.

NTCLE201E3C90028 Thermistor has many uses in industry, like HVAC systems, temperature control in washing machines, thermal protection in electronic components, and medical diagnostic devices just to name a few. Its low cost and small size make it a popular choice among temperature sensing applications. It is even used for detecting temperature differences to detect air flow or velocity.

At the heart of NTCLE201E3C90028 is a semiconductor material made from metal oxides such as nickel, cobalt, iron or manganese. This material exhibits a special behavior in that its electrical resistance decreases as the temperature rises. In other words, it has a Negative Temperature Coefficient. The resistance of a typical NTCLE201E3C90028 thermistor is around 60-100 ohms at 25°C (77°F) and decreases by about 0.3 ohms every °C (1.8°F) that the temperature rises.

To measure or control temperatures, NTCLE201E3C90028 thermistors are connected to a voltage or current source of some type. The thermistor’s resistance will vary depending on the temperature of the object being measured. The resistance is then measured and used to calculate the temperature. Generally, these thermistors are connected in a series circuit, with the power source connected to one end and the other end measuring the voltage across the thermistor. The voltage across the thermistor is then used to calculate the resistance which in turn is used to calculate the temperature.

Additionally, NTCLE201E3C90028 thermistors are also often used in conjunction with a voltage or current regulator. This is a specialized circuit that will adjust the power supply current or voltage in order to keep the resistance of the thermistor within a specified range. This allows greater accuracy during long-term temperature measurement applications.

NTCLE201E3C90028 thermistors are widely available and used in many applications. Their low cost and small size make them a popular choice for temperature sensing applications. Applications where long-term stability and precision is important require the use of a voltage or current regulator in conjunction with the thermistor to provide the highest accuracy. This combination of thermistor and regulator makes it possible to reliably monitor and control temperatures with high accuracy at a very low cost.
