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.
