Resistor networks, arrays, which can also be referred to as resistor packs, are electrical components found in nearly all electronics, able to perform several different tasks. One of the most famous products of this type is the AF164-FR-0763R4L, an adjustable resistor network/array component produced by Fujitsu in Japan.

The AF164-FR-0763R4L is a 4-bit array resistor component, which consists of 4 “ladder” resistors, each of which can be adjusted by connecting an output pin to any of the 3 jumper pins. Each of the integrated 4 resistors can be set to one of 8 resistance values, from the maximum resistance of 47.5KΩ, to the minimum of 0.5KΩ.

The AF164-FR-0763R4L has a very wide range of possible applications, and is primarily used by engineers in industries such as consumer electronics and automotive manufacturing, as an adjustable resistance or pull-up/pull-down voltage regulator, or as a voltage divider. It can also be used as an isolation resistor, in order to prevent spurious signals from travelling between two and more components. Additionally, it can be used to reduce voltage drops and to help keep power readings within acceptable limits.

In terms of its working principle, the AF164-FR-0763R4L is designed with 4 “ladder” resistors, which have been proven to be effective for controlling current over long distances. The 4 resistors also use the resistor ladder configuration, which allows for a wide range of resistance values to be set.

The ladder configuration consists of four resistors connected in series at each end, with the centre three resistors being connected in a ladder configuration. The current flow is controlled by connecting the output pin to any of the three jumper pins. The jumper pins, when connected, will adjust the overall resistance value by changing the resistance of the middle resistor in the ladder.

The AF164-FR-0763R4L is a highly versatile adjustable resistor network/array component for use in multiple industries. It is designed with a highly resistive ladder configuration, which makes it ideal for long-distance current control and voltage regulation, over a wide range of resistance values. Furthermore, it can be used as an isolation resistor, in order to prevent spurious signals from travelling between components, and also to help reduce voltage drops and power readings within acceptable limits.
