RA204R0J

Temperature Sensors - NTC Thermistors

NTC thermistors are temperature sensors that feature a negative temperature coefficient, meaning they become more conductive when their temperature rises. This makes them ideal for numerous temperature measuring and sensing applications. The RA204R0J is a temperature sensor specifically designed for the temperature sensing aspect in these applications.

The RA204R0J is a high-precision Surface Mounted Temperature Sensor manufactured by NEC. This temperature sensor is known for its ease of use and accurate readings and is capable of measuring temperatures ranging from -40°C to 150°C. It has a good response time of 50ms and offers a temperature accuracy of ±2.5°C over its full temperature range. It has a total of 144 pins connected to the thermistor body, and connection between the pins and the body is made via a method known as die attach technology.

The RA204R0J has a wide range of applications, including temperature sensing and control in consumer products such as dishwashers and washing machines, as well as in HVAC/R equipment, medical equipment, and automotive systems. It is also used as a temperature sensor in industrial applications such as soldering baths and 3D printing platforms. The RA204R0J can also be used in home appliances such as air conditioners, refrigerators, and water heaters.

The primary working principle of the RA204R0J is based on the NTC thermistor phenomenon, which states that the resistance of the thermistor decreases with an increase in temperature. The RA204R0J uses this phenomenon to measure temperatures accurately and precisely. It consists of two main components: a thermistor body and a heat slug. The thermistor body is made up of a metal cylinder filled with a ceramic material that can expand and contract with temperature changes. The heat slug is a metal plate that covers the ceramic material and converts it into electrical resistance changes. As the temperature of the environment around the RA204R0J changes, the resistance of the thermistor body also changes, and this change is measured by the heat slug.

In conclusion, the RA204R0J is a high-precision temperature sensor designed on the basis of the NTC thermistor phenomenon. It has a wide range of application fields that make use of its accurate temperature readings and response time. Its primary working principle is based on the phenomenon of the resistance of the thermistor body changing with temperature changes, which is measured by the heat slug.
