RT1203B7TR13

Resistor Networks, Arrays are widely used in a variety of applications, due to their simplicity and ability to be further integrated into larger circuit systems. The RT1203B7TR13 is a type of resistor array produced by Panasonic that has been designed for high speed control applications. It is a two-layer thick film relative humidity sensor with a detection range of approximately 10 percent RH to 98 percent RH or greater.

The RT1203B7TR13 is composed of a 3X7 array of resistors, or 15 resistors total, connected in a matrix. It utilizes a relative humidity sensing element consisting of Pd/Pt metal film using an electrolytic capacitor for moisture measurement. The resistors used present a significant amount of stability with low temperature and humidity drift, and the relative humidity sensing element has an upper detection limit of approximately 98 percent RH or greater. In its only application, the sensor is used for temperature and humidity measurement.

The RT1203B7TR13 operates with a 3.3 V DC supply voltage, and a typical I/O requirement. The input voltage range is 0.8 V, and the output voltage range is 0.2 V. The RT1203B7TR13 also features a signal detection range of 1 ppm/RH, and an accuracy of 0.1 %RH, both of which are significantly better than any current temperature/humidity sensors on the market.

The RT1203B7TR13 is well-suited for applications in places where temperature and humidity control is crucial such as in large computer server rooms or in industrial process control. This type of resistor array is extremely versatile and offers excellent performance, making it one of the most popular resistor networks/arrays on the market.

The working principle behind the RT1203B7TR13 is relatively simple. It utilizes a relative humidity sensing element consisting of a Pd/Pt metal film and an electrolytic capacitor. When exposed to moisture in the air, the Pd/Pt metal film reacts by changing its electrical resistance. This change in resistance is measured by the RT1203B7TR13, and is then output as either a 0.2 V to 0.8 V voltage signal or as a 1 ppm/RH digital output signal.

The RT1203B7TR13 is a highly reliable device designed for use in a variety of temperature and humidity control applications. With its high levels of accuracy and signal detection range, it is a dependable and cost-effective solution for many industries. Its versatility and robustness allow it to be integrated into a wide range of circuit systems, making it an invaluable part of any system that requires temperature and humidity control.
