NTC thermistors are thermally sensitive resistors that are utilized to measure temperature which varies its electrical resistance. The NTCS0805E3103FMT is a negative temperature coefficient (NTC) thermistor for temperature sensing application, which includes general temperature measurement and temperature compensation. It is an 8.0 mm×5.0 mm×2.8 mm flat disc-shaped thermistor and is PNP compatible with standard surface-mount technology (SMT).

Application field

The NTCS0805E3103FMT is mainly used for temperature sensing and protection. It is commonly used in products such as air conditioners, household appliances, automotive control systems and temperature sensing equipment. NTC thermistors are widely accepted due to its long lifespan, versatility and accuracy. It also offers excellent mechanical and electrical properties, good corrosion resistance, excellent temperature stability and insulation resistance.

Working principle

NTC thermistors have a negative temperature coefficient property, which means that when the temperature rises, the resistance of the NTC thermistor decreases. This is due to the shrinkage of the molecules in the thermistor which causes more of them to come together, allowing for a decrease in resistance. When the temperature drops, the resistance increases due to an increase in the distance between the molecules.

The NTCS0805E3103FMT is used to measure temperature changes using its resistance change. It uses the voltage reading to measure the temperature change with a resistor-capacitor (RC) circuit, and the voltage or time constant (constant voltage or current) is used to measure the temperature. For temperature sensing and protection applications, the NTC thermistor should be connected in series with a resistor, and the voltage across the resistor can be measured to determine the temperature of the thermistor.

Conclusion

The NTCS0805E3103FMT is a convenient and reliable thermistor used for temperature measurement and temperature protection. It has a negative temperature coefficient Property and a wide range of applications. This type of thermistor is ideal for current sensing and overheating protection applications. The NTC thermistor can be easily integrated into circuit boards and is a cost-effective method for sensing temperature.
