Temperature sensors are one of the most commonly used technologies in the industrial and medical industries. They are used to measure temperature variations in a medium, whether it be solid, liquid or gas. NTC thermistors are one type of temperature sensor and they provide a convenient and accurate method of temperature measurement. The ERT-J1VT472J, available from Panasonic, is an NTC thermistor that has a wide range of applications.

An NTC thermistor is a component whose resistance reduces with increasing temperature. It is made from a sintered ceramic material that contains either manganese or cobalt oxide. They have a negative temperature coefficient of resistance, meaning that the resistance decreases with an increase in temperature.

The ERT-J1VT472J has a sensitivity of 47K and a resistance tolerance of +/-5%. The thermistor is suitable for use in a wide range of temperatures, from -25 to 200 Celsius. The temperature range is limited by the material and design of the thermistor, and the temperature coefficient is constant and linear at up to 0.35%/K. The component is a standard 0603 form factor, enabling it to be integrated into a range of PCBs and systems.

The ERT-J1VT472J thermistor is used in many applications. Some of the most common applications include temperature monitoring in HVAC systems, medical equipment, power supplies, instrumentation, and automotive systems. The significant elements of the thermistor’s design mean that it can accurately and reliably measure temperatures in these applications.

The working principle of the ERT-J1VT472J is simple. As the temperature increases, the resistance of the thermistor decreases. This change in resistance is measured by a circuit connected to the thermistor. A simple voltage divider circuit is typically used. This circuit measures the voltage drop across the thermistor, which is then used to calculate the temperature.

In conclusion, the ERT-J1VT472J is an NTC thermistor that has a wide range of applications. Its temperature range and tolerance make it suitable for use in a variety of systems, and its working principle is simple to understand and implement. Owing to its relatively small size, it can be easily integrated into PCBs, making it an ideal choice for many temperature monitoring applications.
