PTC thermistors, or Positive Temperature Coefficient thermistors, are a type of temperature sensor used in a variety of applications. They are often used as temperature-dependent switches, current- or voltage-dependent control elements, and circuit protection devices. The TFPT0805L1000KV is a specific PTC thermistor that shows higher resistance when exposed to temperatures greater than its predetermined critical temperature.

Application Field

The TFPT0805L1000KV is a general purpose PTC thermistor and can be used in a variety of different applications. Some of these applications include controlling various types of electronic devices, over-current protection, temperature sensing, thermal cutoff, and over-temperature protection in computers, consumer electronics, automotive, industrial, and household appliances. The TFPT0805L1000KV can also be used to sense the temperature of air or liquid, providing a signal that can be used to control other components.

Working Principle

The TFPT0805L1000KV is a resistive temperature sensor made of a polycrystalline material that has a positive temperature coefficient of resistance. This means that its resistance increases when exposed to a higher temperature. Its operating temperature range is from -30°C to +120°C and its resistance starts to rise when the temperature is higher than its specified critical temperature. The TFPT0805L1000KV is designed to maintain a steady resistance throughout its operating temperature range.}

When exposed to temperatures greater than its predetermined critical temperature, the TFPT0805L1000KV will start to experience an increase in resistance. As the temperature continues to rise, the resistance of the thermistor increases until the point where its resistance reaches its maximum value. At this point, it is said to have "tripped" and will no longer conduct an electric current.

The TFPT0805L1000KV\'s resistance is also affected by its body size and type of material used in its construction. It is typically made of a polycrystalline material that is resistant to thermal shock and can be used in a wide range of operating temperatures.

Conclusion

The TFPT0805L1000KV is a general purpose PTC thermistor that has many applications in different fields. It is designed to have a positive temperature coefficient of resistance and can be used to control various types of electronic devices, as well as provide temperature sensing, over-current protection, and thermal cutoff. Its unique design allows it to maintain a steady resistance throughout its operating temperature range, allowing for accurate temperature detection and/or protection.
