Temperature Sensors - PTC Thermistors are widely used in temperature detection and control technologies. The TFPT0805L3900FZ PTC Thermistor is one such device that is essential for accurate temperature control applications. This article will explain the application field of this PTC thermistor and how it works.

Application Fields

The TFPT0805L3900FZ PTC Thermistor is designed for small and medium sized temperature sensing applications. It has a resistance that increases when temperature rises, so it can be used as a temperature dependent switch. Typical uses for TFPT0805L3900FZ PTC Thermistor include temperature monitoring and control in:

• Household appliances
• Motor vehicle systems
• Office automation equipment
• Power supplies
• Telecommunications
• Lighting systems
• Industrial machinery

Working Principle

The PTC thermistor is a ceramic semiconductor component that is composed of positive temperature coefficient (PTC) material. This material exhibits high resistance to electrical current at lower temperatures and a dramatic decrease in resistance when temperature rises. The resistance characteristics of PTC thermistors can be further manipulated by altering the composition of the material, or by changing the geometry of the device.

When a current flows through the PTC thermistor, its resistance increases as the temperature increases. This phenomenon is known as the temperature dependence of the PTC thermistor. This phenomenon enables PTC thermistors to be used in temperature sensing applications. The resistance of the PTC thermistor can be used to measure the temperature of an object.

The TFPT0805L3900FZ PTC thermistor has a resistance that changes from 0.5 ohms at 25°C to 10 ohms at 125°C. This makes it ideal for measuring temperatures between 25°C and 125°C, which are typical operating temperatures for many electronic devices. The TFPT0805L3900FZ PTC thermistor also has a wide temperature sensing range and is fast responding to changes in temperature.

Conclusion

The TFPT0805L3900FZ PTC thermistor is a versatile temperature sensing device for small to medium sized application that requires accurate temperature control. This PTC thermistor has a noticeable resistance increase with increased temperature, making it ideal for measuring temperatures between 25°C and 125°C. It has a wide temperature sensing range and is fast responding to changes in temperature, making it a reliable choice for temperature sensing applications.
