PTC thermistors are temperature sensors used in a variety of applications across the globe. PTFT0805L0030JV is one of the most popular PTC thermistors in the market. It is a tubular thermistor developed for temperature measurement and control, temperature compensation and surge protection.

PTFT0805L0030JV is a epoxy-sealed thermistor, in which the temperature sensing element is encapsulated in a dual-layer cylindrical epoxy material. The construction of this PTC thermistor is designed to provide high accuracy, fast switching time and low cost. In addition, it provides excellent accuracy and stability of the thermal characteristics.

The main applications of PTFT0805L0030JV are in household appliances, automotive electronics, office automation and electronic instrumentation. This PTC thermistor can be used for temperature measurement and control, with accuracy of plus or minus 0.1 degree Celsius, and switching time of less than 1 second. It is also used in temperature compensation and surge protection applications.

The working principle of PTFT0805L0030JV is based on the observation that the electrical resistance of certain materials changes in response to temperature. PTC thermistors are a type of thermistor composed of a ceramic material, typically oxide-based, that exhibits a positive temperature coefficient (PTC) of electrical resistance. Generally, as the temperature increases, the resistance of the thermistor increases, resulting in a decrease in current through the circuit.

The PTFT0805L0030JV has a resistance of 30 ohms at room temperature and a nominal temperature coefficient of 4.2 %/K. This temperature coefficient is stored in the thermistor’s memory and used to calculate the temperature of the environment. In addition, the thermistor exhibits a high self-heating effect, which can result in a uniform temperature distribution within the device.

PTFT0805L0030JV has a wide operating temperature range from -40 to +125 °C. It is also resistant to electrical noise, chemical corrosion and other environmental factors. Furthermore, it has excellent environmental durability, which makes it suitable for long-term operation in harsh environments.

In summary, PTFT0805L0030JV is a robust and reliable PTC thermistor designed to measure and control temperature. It has a wide operating temperature range, excellent accuracy and stability, wide resistance range, high self-heating effect, and excellent environmental durability. These attributes make PTFT0805L0030JV ideal for use in household appliances, automotive electronics, office automation, and electronic instrumentation applications.
