Temperature Sensors - PTC Thermistors play an important role in temperature control and overheat protection of hundreds of electrical and electronic products. In this article, we will discuss the application field and working principle of PTFT0805L1500JW, one of the most popular PTC thermistors.

PTC thermistors are made up of a semiconductor material that has a positive temperature coefficient (PTC). This means that as the temperature increases, resistance increases. Along with providing information to the customer, this phenomenon can be used to control the temperature of the device. For example, with PTFT0805L1500JW, there is a temperature-sensitive resistor that will protect the device from thermal overload. As the temperature of the device rises, the thermistor’s resistance increases, causing the circuit current to drop and reducing the power applied to the device.

The application of PTFT0805L1500JW can be found in a wide variety of fields, from industrial and automotive to medical and consumer electronics. In industrial applications, it is widely used as a current cutoff point in electric motors, circuit breakers, and other high-power electric equipment, to protect them from overheating and electric overload. In automotive applications, it can be used to protect car batteries, internal combustion engines, and other parts from overheating and electrical malfunctions. In medical applications, the PTC thermistor is often used as a high temperature fault detector, especially in larger medical facilities and clinics.

Apart from its application, it is also important to understand the working principle of PTFT0805L1500JW. The thermistor consists of a semiconductor material with a positive temperature coefficient (PTC), usually made of ceramic or polymeric material. When the ambient temperature increases, the resistance of the PTC thermistor increases accordingly. When the temperature threshold is exceeded, the thermistor reduces the circuit’s current and voltage. This triggers the connected device to automatically switch off, protecting it from overheating. The thermistor can then be reset manually or automatically when the temperature returns to a safe level.

In conclusion, PTFT0805L1500JW is a very popular PTC thermistor used in a wide range of applications, from industrial to automotive to medical. Its working principle is based on the fact that the semiconductor material has a positive temperature coefficient, meaning its resistance increases as the temperature of its application increases. This phenomenon provides the device with an efficient overheat protection system, reducing the current and voltage applied to the device to prevent damage.
