Temperature Sensors - PTC ThermistorsPTC thermistors are temperature-sensitive devices that employ the positive temperature coefficient (PTC) effect in an integrated circuit. This effect occurs when a component’s temperature rises, causing the device to attempt to reduce or limit the current flow through the circuit. This attempt to prevent thermal runaway acts as a safeguard for the circuit and its components.TFPT1206L2201FV is one of the most popular PTC thermistors on the market today, often used in a wide variety of applications. As a temperature sensing device, it’s most popular application is in cellular phones, laptops, car audio systems and video game consoles. It can also be found in heated car seats, air conditioners and computer cooling systems.The working principle of the TFPT1206L2201FV is quite simple. It’s composed of a PTC thermistor heat element and a base element connected in a heat conducting path. When the temperature of the thermistor’s thermal element goes above a certain level, the thermistor becomes highly resistive, limiting or restricting the current flow through the circuit. This act functions as an over-current protection mechanism in order to prevent the circuit from experiencing thermal overshoot or runaway.The TFPT1206L2201FV is designed as a compact and light weight device, with a body measuring only 12mm x 6mm. It’s designed to provide high accuracy over a wide temperature range, with an operational temperature range of -40°C to 125°C. The device also features a low operating voltage of 2.2V and low leakage current of 0.6mA. It’s designed to be capable of operating at frequencies of up to 5MHz.The TFPT1206L2201FV also offers excellent thermal cyclability with minimal performance effects. It also has a high overload limit of 1.25A and low self-heating of 0.3K. Its high overload limit and low self-heating make it ideal for applications in which sudden spikes in current are present. The TFPT1206L2201FV also offers high temperature stability and can be operated in either the positive or negative temperature coefficient (PTC/NTC) mode.Overall, the TFPT1206L2201FV PTC thermistor is an ideal temperature sensing device that is suitable for a wide variety of applications. Its small size and high accuracy make it ideal for applications in which space is limited and accuracy is a priority. Its low operating voltage, low leakage current, high overload limit and low self-heating make it an excellent choice for a variety of different applications.
