Temperature Sensors - PTC Thermistors are widely used to measure temperatures in various applications. Among them, the B59810T1120A62 is an example of a popularly used PTC thermistor. It is designed to measure temperatures ranging from -40 to 125°C (-40 to 257°F).

The B59810T1120A62 PTC thermistor uses an NTC thermistor element. This type of thermistor is made of a metal oxide ceramic material that has a highly positive temperature coefficient of resistance (TCR). It also has a relatively high switching resistance.

Temperature is measured by the thermistor\'s resistance, which varies with changes in temperature. When the temperature around the thermistor increases, so does its resistance. When the temperature decreases, its resistance also decreases.

The B59810T1120A62 PTC thermistor has a resistance of 1.2KΩ at 25°C (77°F). This high resistance prevents current flows. Since this thermistor has a positive temperature coefficient, its resistance increases when the temperature rises, and when it reaches a certain temperature, the resistance of the thermistor will abruptly switch from a high to a low resistance state. This phenomenon is referred to as the Curie point, and it is a useful property of PTC thermistors.

The B59810T1120A62 PTC thermistor is used in a wide range of applications. It can be used to protect electrical circuits and electronic components from overheating due to high temperatures. It is commonly used in air conditioning and heating systems, hot water and refrigeration systems, and in medical and industrial equipment. It can also be used as a temperature controller in temperature measurement circuits.

In addition, the B59810T1120A62 PTC thermistor is used in a variety of power saving applications. In these designs, the thermistor\'s curie point is utilized to control the current flow to lighting and other electrical devices. When the ambient temperature is low, the thermistor\'s resistance is low, allowing the circuit to draw more current than is necessary. When the temperature rises, the resistance increases, limiting the current flow and saving energy.

The B59810T1120A62 PTC thermistor is a reliable device for measuring and controlling temperatures in a wide range of applications. Its high resistance, positive temperature coefficient, and curie point make it a versatile and reliable choice for temperature sensing and control.
