Product Details

Overview of Thermistors:

The material of negative temperature coefficient (NTC) thermistor is a ceramic made by firing oxides of manganese (Mn), nickel (Ni), cobalt (Co) and other components. This ceramic forms the electrode. Its appearance shape usually has leads

Type, sheet type, etc.

Temperature characteristics of thermistor

The resistance value of a negative temperature coefficient (NTC) thermistor is shown in the following figure, and the exponent decreases with temperature.

The resistance value of a negative temperature coefficient (NTC) thermistor can be represented by the following equation and can be used as a wide range of temperature sensors

RT＝R0expB (1/T-1/T0)

Here, RT is the resistance value when the ambient temperature is T (K), R0 is the resistance value when the ambient temperature is T0 (K), and B is the constant B.

The B constant shows a tendency for the resistance value of a thermistor to change with temperature, which is the basic characteristic of a negative temperature coefficient (NTC) thermistor.

According to the temperature, there may be slight changes, so it should be noted that the value of the B constant may vary depending on the defined temperature.

Technical specifications:

Negative Temperature Coefficient (NTC) thermistors exhibit a 3-5% change in resistance value with temperature variation. It is often used as a general temperature sensor in electronic devices such as smartphones. Using intelligence

Have you ever experienced "how did your phone get hot" while using it? It can be said that a thin and high-performance smartphone is like a small computer. However, due to the lack of computer cooling fans installed on the phone

The body will become hot. So, precision components that are sensitive to heat may be at risk of damage.

Use negative temperature coefficient (NTC) thermistor to measure the temperature inside the smartphone, and then use this temperature information to control the temperature in various ways.
