Resistor Networks, Arrays, are electronic components that are commonly used to control the flow of electricity in circuits.

628B472TR4 is a type of fixed resistor array designed for Reliable and Versatile Digital Control applications. This type of resistor arrays is composed of four independent resistors with the same resistance. The purpose of these resistors is to provide an affordable, low-power variable resistor solution for circuit design applications. The resistors are connected in a linear arrangement and feature low on-resistance, low noise, and low temperature coefficient.

The main application field of 628B472TR4 resistor arrays can be found in digital processes like voltage monitoring, impedance matching, temperature measurement, calibration, etc. Due to its low on-resistance, this type of resistor arrays can be used in high-performance analog circuit designs of amplifiers.

The working principle of 628B472TR4 resistor arrays is based on the ability for the resistors to create a voltage drop across its terminals. When the array is connected to a power source, the current passing through it creates a voltage drop across the resistors in the array. This voltage drop is maintained until the resistors reach their maximum rating, when the current increases and the resistance decreases.

The 628B472TR4 resistor arrays are designed with a linearity accuracy of 0.00025%, a very low temperature coefficient of 0.2ppm/ºC and a wide temperature range of -55ºC to +175ºC. The resistance stability can be improved by using a metal film, which provides improved temperature stability and better load stability.

In terms of manufacturing, the 628B472TR4 resistor arrays can be manufactured by using either thick-film or thin-film process technologies. The overall design of the array is simple and easy to modify for customized requirements. The resistors are connected together by soldering or welding, depending on the application.

In conclusion, 628B472TR4 resistor arrays are reliable and versatile electronic components for digital control applications. They are designed for low noise, low temperature coefficient, and wide temperature range. They can be manufactured with either thick-film or thin-film process technologies and their resistance can be adjusted with an external control. The linearity accuracy of the resistor array is 0.00025%, which ensures accurate performance.
