Temperature Sensors - PTC Thermistors are temperature sensing components made of a material with a semi-conductor element which exhibits “positive temperature coefficient” (PTC). This means that as they experience an increase in temperature, their resistance increases. PTC thermistors are made in the form of planar, tubular and disc components.

The PTFT0805L2200JV is a PTC thermistor that is made in the form of an 0805SMD chip. It has a resistance of 2.2KOhm at 25℃ and the resistance will increase with temperature as the PTC effect kicks in. It has a material code FK5 and its maximum temperature rating is 150℃.

The application of PTFT0805L2200JV PTC thermistor includes temperature related motor protection, equipment monitoring, temperature control in printers and copiers, and the detection and interruption of abnormal temperatures in internal combustion engines. Its fast temperature compensation and positive temperature coefficient (PTC) characteristics make it suitable for a wide range of applications.

The working principle of PTFT0805L2200JV is that as the temperature increases, its resistance value rises too. This allows the PTC to detect and indicate any changes in temperature that may occur. As the temperature increases, the current flow through the thermistor is decreased, which can be detected by current measuring instruments. The PTC thermistors that have a positive temperature coefficient property (like the PTFT0805L2200JV) are used to measure the temperature changes accurately as the current that flows through the thermistor is reduced by the change in resistance.

PTFT0805L2200JV is also used as temperature switching components in both heating and cooling circuits. In situations where it is desired to switch a heating circuit on or off at predetermined temperatures, the PTFT0805L2200JV can be used as an on/off switch. The PTC thermistor is placed in the circuit and as the temperature rises or falls, its resistance changes accordingly, thus the circuit state will switch from ON to OFF automatically.

In summary, PTFT0805L2200JV is a PTC thermistor which used as a temperature sensing component and temperature switching component. With its fast temperature compensation and positive temperature coefficient (PTC) characteristics, it is often used in temperature related motor protection, equipment monitoring, temperature control in printers and copiers, and the detection and interruption of abnormal temperatures in internal combustion engines.
