Resistor Networks, Arrays involve the use of two or more resistors combined to produce specific resistance values, characteristics and patterns. This article discusses the application field and working principle of the 4820P-2-471LF resistor array.

The 4820P-2-471LF resistor array is an 8 pin device that consists of two 0.1 percent thin-film chip resistors. The device is constructed using a temperature-dependent resistor technology which allows the resistors to adjust to different levels of temperature in the environment. The device is ideal for applications where stability in resistance values is desired and is used frequently in areas such as telecommunications, wireless communications, and automotive industries.

The application field of the 4820P-2-471LF resistor arrays in two fold: one, it is used to adjust resistance values to compensate for temperature and two, it is used to measure current. In terms of temperature compensation, the thin film resistor can maintain a constant resistance even when subjected to a temperature change. This makes the device ideal for applications in telecommunications as temperature effects the resistance of copper and other metals used for wiring, making it difficult to maintain an optimal level of resistance values. In addition, as the device is able to maintain a stable resistance over a temperature range of -55°C to +125°C, it is also ideal for applications in automotive industry, and can be used to measure the temperature of components.

In terms of current measurement, the 4820P-2-471LF can be used as a current sensing device. It is designed with a pair of resistors operating in series that can measure current by measuring the voltage across each resistor. This type of resistor array is referred to as a current shunt and is commonly used in applications such as motor control, power monitoring, and battery pack monitoring.

The working principle of the 4820P-2-471LF is based on the principle of resistors in series. The device is composed of two resistors (in series) which allow current to pass through them from one negated node to the other positive node. The current passing through the resistors is divided up proportionally according to the values of the resistors, in this case, 0.1%. The voltage drop across each resistor is proportional to its resistance and this voltage drop can be used to measure the current passing through the resistors.

In conclusion, the application field and working principle of the 4820P-2-471LF resistor array includes temperature compensation and current measurement. It consist of two resistors operating in series that allows current to pass through them and divide proportionally by the resistance of each resistor. This voltage drop across the resistors can then be used to measure the current passing through the resistors making it ideal for applications such as telecommunications, wireless communications, automotive industry and motor control.
