5.Application Scope
*Conversion power supply, switching power supply, UPS power supply.
*Various types of high-power lighting fixtures.
*Electric heater.
The NTC Thermistor has a dissipation coefficient of 0.2mW/℃, which means it can dissipate 0.2mW of power for every degree Celsius of temperature change. This makes it suitable for use in low power applications where energy efficiency is critical. The maximum power rating for this product is 100mW, which means it can handle up to 100mW of power without getting damaged. The NTC Thermistor is designed to be mounted on the surface of a circuit board, which makes it easy to integrate into existing designs.
The NTC Thermistor provides an analog output signal that is proportional to the temperature being measured. This means that as the temperature increases, the output signal from the thermistor will also increase. This makes it easy to interface with other electronic components and systems. The analog output signal can be converted into a digital signal using an analog-to-digital converter (ADC) if required.
The MF11 temperature compensated thermistor is a type of NTC Thermistor that has a built-in compensation circuit. This compensation circuit is designed to provide accurate temperature sensing even in environments where the ambient temperature may fluctuate. The MF11 temperature compensated thermistor is ideal for applications where temperature accuracy is critical.
The MF5 Single-ended glass sealed thermistor is another type of NTC Thermistor that is designed for use in high-temperature environments. This thermistor is constructed using a glass sealed design that provides excellent stability and durability at high temperatures. The MF5 Single-ended glass sealed thermistor is ideal for applications where high-temperature sensing is required.
Overall, the NTC Thermistor is a highly versatile and reliable temperature sensing solution that is ideal for a wide range of applications. With its surface mount design, low power dissipation, and analog output signal, it is easy to integrate into existing designs and systems. Whether you need the accuracy of the MF11 temperature compensated thermistor or the high-temperature stability of the MF5 Single-ended glass sealed thermistor, the NTC Thermistor is sure to meet your needs.
