Temperature Sensors - PTC Thermistors

PTC thermistors, or Positive Temperature Coefficient thermistors, are a type of temperature sensor which is used in a variety of settings. As their name implies, they operate on the principle of a positive temperature coefficient, meaning that as temperature increases, the resistance of the thermistor also increases. The TFPT0805L4701FZ PTC thermistor is a type of surface-mount device specifically designed for use in temperature sensing applications.

In general, the TFPT0805L4701FZ can be used for any temperature measurement or control application. Specifically, it is commonly used for mobile phone thermal management, water heater thermal management, air conditioners, refrigerator temperature control, overheat protection for motors and other similar applications.

The working principle of the TFPT0805L4701FZ is based on the fact that the resistance of the thermistor increases as the temperature increases. By measuring the resistance of the thermistor, the temperature of the device can be easily determined.

The TFPT0805L4701FZ features a low total thermal impedance, low thermal resistance junction to lead, and a fast response time. It has an operating temperature range of -40°C to +110°C, a breakdown voltage of 1V, and is rated for a power dissipation of 1.3 watts. It is available with different lead configurations, and its dimensions are 0.16"x 0.08"x 0.08" (4.0mm× 2.0mm × 2.0mm).

In conclusion, the TFPT0805L4701FZ is a type of PTC thermistor specifically designed for temperature sensing applications. It is suitable for a wide variety of applications, including mobile phones, water heaters, air conditioners, refrigerators, and motor overheat protection. It features a low total thermal impedance, low thermal resistance junction to lead, and a fast response time. The TFPT0805L4701FZ operates on the principle of a positive temperature coefficient, meaning that as the temperature increases, the resistance of the thermistor also increases.
