Temperature Sensors - PTC Thermistors

Temperature Sensors - PTC thermistors are used to measure changes in temperature. They are thermistors that have a positive temperature coefficient (PTC) which means that the resistance of the thermistor increases with an increase in temperature causing an increase in the voltage drop across it. This increase in voltage allows for the measurement of temperature accurately and reliably.

One such thermistor is the TFPT0805L2001JF. This is a PTC thermistor with a temperature range of -40°C to 225°C. It has a R25 (resistance at 25°C) value of 2001 ohms and a B25/85 of 3480 ±1 K. Due to its small size and low resistance, it is actually used as a low-power heater. Its physical features include an M0805 case size with a height of 0.20 mm, a diameter of 0.80 mm, and a lead spacing of 1 mm. Additionally, it consumes approximately 1 mW of power when operated at a 75°C temperature difference.

In terms of application field, the TFPT0805L2001JF is ideal for industrial applications, such as controlling the temperature of motors, pumps, and other mechanical parts. It is also often used in temperature range monitoring and temperature control systems, as well as in cars and other automobile parts. Additionally, it can be used in a wide range of industrial environments from factories to laboratory setups, and in medical or laboratory equipment.

The working principle of the TFPT0805L2001JF is quite simple. The thermistor acts as a thermal resistor. When current is applied to it, resistance increases with an increase in temperature resulting in an increase in voltage drop. This change in voltage can then be used to measure and monitor the temperature of the environment. Furthermore, the TFPT0805L2001JF can also act as a low-power heater due to its small size and low resistance. This is because when current is applied to it, the heat generated increases the temperature of the environment.

In conclusion, the TFPT0805L2001JF PTC thermistor is a temperature sensor ideal for industrial applications. It has a wide temperature range (-40°C to 225°C) with a R25 (resistance at 25°C) value of 2001 ohms and a B25/85 of 3480 ±1 K. It is also used as a low-power heater due to its small size and low resistance. Its working principle is simple, as the increase in resistance with an increase in temperature results in a voltage drop that is proportional to the change in temperature.
