NTC thermistors are temperature sensitive devices which are widely used in temperature sensing and compensation, such as in cooling water systems, cooling towers, heating appliances and so on. In this article, we are going to discuss the application field and working principle of NTC0805J2K2.

NTC0805J2K2 is a negative temperature coefficient (NTC) thermistor. It has a resistance of 2K ohm at 25°C and a dissipation coefficient of 1W. It also has an operating temperature range of -40 to +125°C. NTC0805J2K2 is widely used in temperature sensing applications. It can be used for temperature compensation in cooling water systems, cooling towers, and heating appliances. It is also widely used in the automotive industry for air conditioner cooling control and radiator cooling fan speed control.

The working principle of NTC0805J2K2 is based on its resistance versus temperature characteristics. When the temperature changes, the resistance value of the NTC thermistor also changes. The resistance of the thermistor increases with the reduction in temperature, and vice versa. Thus, when the temperature increases, the resistance decreases, creating a negative temperature coefficient.

The resistance character of NTC0805J2K2 can be measured using a multimeter. The voltage across the thermistor is applied and the resistance can be calculated. It is important to note that the voltage should not exceed the maximum voltage limit of the thermistor. If the voltage is too high, it may damage the thermistor.

In addition, NTC0805J2K2 has a wide range of applications. It can be used as temperature sensor in cooling water systems and cooling towers, for motor control, microprocessor monitoring, temperature compensation and power switching. It can also be used in heating appliances to control the temperature accurately.

In conclusion, the NTC0805J2K2 is a widely used NTC thermistor with a wide range of applications. It has a resistance of 2K ohm at 25°C and an operating temperature range of -40 to +125°C. Its working principle is based on its resistance versus temperature characteristics, which changes with temperature. The thermistor has a wide range of applications, such as temperature sensing and compensation, motor control, microprocessor monitoring, temperature compensation and power switching.
