Temperature Sensors - NTC Thermistors

NTC thermistors are an important device for sensing temperature and to limit power in electrical application. The NHQ502B355T5 is a commonly used NTC thermistor that is designed to be used in a wide range of applications and to operate at extreme temperatures. The NHQ502B355T5 is constructed of a ceramic core and two anodes and it has a resistance range of 5Ω to 500kΩ. It is a thermally sensitive element that responds to changes in temperature by changing its resistance.

The NHQ502B355T5 is a popular choice for temperature sensing applications as it exhibits a wide temperature range and an especially low temperature coefficient of resistance (TCR). Its low TCR and wide temperature range make it ideal for use in temperature-sensing devices such as thermocouples, RTDs and thermistors. The NHQ502B355T5 is also used in automobile electronic control systems and other automation control systems. In addition, it is used for over-temperature limiting, thermal protection and temperature compensation in many industrial, automotive and consumer electronics.

The working principle of the NHQ502B355T5 is based on the principle of negative temperature coefficient (NTC). The NTC thermistor behaves like a resistor whose resistance decreases with increasing temperature. When the temperature increases, the resistance of the thermistor decreases. The resistance-temperature curve of the thermistor is non-linear, so the thermistor is usually either calibrated for a specific temperature or connected to a pulse-width-modulation (PWM) controller with a temperature feedback circuit.

The NHQ502B355T5 can be used in a variety of applications such as temperature sensing, power limiting, protection from overheating, temperature compensation, motion control and electronic control systems. In temperature sensing applications, the thermistor is usually connected to a controller or a measuring device and the resistance is used to calculate the temperature. The NHQ502B355T5 is also used for over-temperature limiting and temperature protection, where the thermistor is used to cut off power in the event of an over-temperature condition. In addition, it is used for temperature compensation, where the thermistor is used to adjust the operating parameters of the device to compensate for changes in temperature.

The NHQ502B355T5 is an ideal choice for a wide range of temperature sensing and protection applications. It is a reliable, cost-effective and temperature-stable NTC thermistor that offers excellent temperature sensing performance and wide temperature range. Its wide range of applications, low TCR and temperature features make it suitable for use in a variety of industries and applications.
