4820P-1-472 Datasheet/PDFThe 4820P-1-472 is a four-terminal resistor network designed for general purpose applications. It is constructed from a combination of four discrete resistors networked in a series-parallel configuration. This resistor network is designed to provide precise current balancing, voltage protection and a precision voltage divider for application fields such as power management, telecommunications, instrumentation and industrial control.
The 4820P-1-472 features four individual resistors in a series-parallel configuration. It is constructed from high quality A grade ceramic resistors with a rated power of 1/10 W and a rated accuracy of 1%. This four-terminal network also comes with a two-pin jumper that allows for the parallel connection of the two inner resistors. This provides an adjustable resistance value which allows for a wide range of potential applications.
Working principle of 4820P-1-472
The 4820P-1-472 functions by providing a precise voltage divider which is necessary in many application fields. Each resistor in the network acts as a “step” in the voltage divider. By adjusting the two values of the resistors, the overall voltage divider match can be set to the desired value. The network functions on the principle of current balancing, such that the current through each resistor is identical.
The current balancing is provided by the offset of the two inner resistors, which are connected in parallel. By changing the total resistance value, the current is then evenly distributed between all four resistors in the network, thus achieving the desired voltage divider. Additionally, this network can also be connected in a series-parallel configuration to provide more flexibility in the voltage division, as each resistor can be adjusted individually.
