This article will discuss the application field and working principle of PTFT0805L1000JV temperature sensors.

Applications of PTFT0805L1000JV

The PTFT0805L1000JV is suitable for a wide range of temperature sensing applications. It can be used for temperature sensing in consumer electronic products such as cell phones, laptops, and home appliances. It can also be used for device temperature protection. Its built-in protection circuit allows it to safely protect the device from overflows while still providing accurate and precise temperature detection. Additionally, it can be used for thermostat applications in heating and air conditioning systems.

Working Principle of PTFT0805L1000JV

The PTFT0805L1000JV operates on the principle of negative temperature coefficient (NTC). NTC thermistors are resistors that change its resistance when subjected to a change in temperature. As temperature increases, the resistance of the thermistor decreases. Conversely, as temperature decreases, the resistance increases. This is due to the change in atomic motion of the thermistor material when exposed to a temperature increase or decrease. This change in resistance is the basis of temperature sensing with PTFT0805L1000JV.

The working range of PTFT0805L1000JV temperature sensors is between -40°C to +105°C. It has a self-heating coefficient of 0.8°C/W with a power dissipation of 3 W. Its rated current is 75mA and its resistance at +25°C is 1000ohm.

Conclusion

In conclusion, the PTFT0805L1000JV temperature sensor is a high-performance thermistor suitable for temperature sensing and device protection in consumer electronic products and home appliances. It operates on the principle of NTC, wherein its resistance is inversely proportional to temperature. The working range of this temperature sensor is -40°C to +105°C and it has a self-heating coefficient of 0.8°C/W with a power dissipation of 3 W. Its rated current is 75mA and its resistance at +25°C is 1000ohm.
