Temperature Sensors – PTC Thermistors are components that measure temperature by depending on special characteristic of certain semiconductor materials. The response of these components to temperature is rate of resistance versus the temperature change. The temperature rate of resistance affects the values of current, voltage, resistance, and power.

The TFPT1206L2201JM is a polycrystalline PTC thermistor, which is divided into four main categories: AC PTC, self-heating PTC, thermal conductive PTC, and high-capacity PTC.

Application Field:

The main application of the TFPT1206L2201JM is in the over-current and over-temperature protection within a system. It can be used to protect battery packs, power supplies, and motors. It is also used in air conditioners, desktop computers, and other electronic systems.

Working Principle:

The working principle of the TFPT1206L2201JM is based on the PTC thermistor. This PTC thermistor is made of semiconductor materials with a positive temperature coefficient of resistance. This means that when the temperature rises, the resistance of the PTC thermistor increases proportionally. The resistance increases by an exponentially increasing degree with the temperature rising. This change enables the device to sense that temperature and respond in different ways.

The TFPT1206L2201JM is a self-heating PTC thermistor, meaning that it utilizes its own body for heat conduction. This means that when the temperature rises to a certain point, the thermistor will begin to dissipate power, self-heating the thermistor’s body. This in turn increases its resistance, which is detected and used as a response. This response can be used to shut down circuits, turn on cooling systems, or activate alarms.

In addition, the PTC thermistor also has an extremely low thermal time constant, which means that it responds to temperature changes within a short amount of time. This makes it ideal for applications that require fast responses to sudden temperature change.

The TFPT1206L2201JM can be used in a variety of applications, including protecting batteries, motors, power supplies, and air conditioners. It is reliable and convenient for use in electronic systems, offering fast responses and efficient protection.
