Resistor Networks, Arrays

Resistor networks, sometimes referred to as arrays, are passive electronic components used to create desired combinations of resistance values, current levels and voltage levels. Many resistor networks are manufactured as discrete components, with resistors connected in a particular predetermined way on a single substrate. Others are constructed of many individual resistors which can be customized to individual specifications. The RP102PJ102CS Resistor Network is a 8-resistor network with ratioed resistance values 1:2:4:8:16:32:64:128.

Applications

Resistor networks are found in a wide range of applications, from electromagnetic compatibility and noise reduction in low-noise preamplifiers and switches, to automation, motors and power supplies. The RP102PJ102CS resistor network is a popular choice for applications in the automotive, medical, transportation and consumer electronics industries.

The RP102PJ102CS is designed primarily for signal conditioning applications such as low pass filters, voltage dividers, and feedback control circuits. It is often used in power supply circuits to reduce voltage ripple, and in low-noise preamplifiers for reducing noise from electronic devices. It is also useful in timing circuits, where it can be used to control the speed of a motor or to create a delay effect in a logic circuit.

Operational Principle

The power of the RP102PJ102CS Resistor Network lies in its ability to combine ratios of resistance values. Each of the 8 resistors is assigned a precise ratio that contributes to the overall resistance ratio, allowing circuit designers to precisely choose the output voltage of a circuit, or the current through a set of components.

The principle of operation of the RP102PJ102CS Resistor Network can be explained using Ohm’s law. Ohm’s law states that the voltage or current through a circuit is proportional to the resistance value of the components in the circuit. By combining a set of resistors in a resistor network, the net resistance value of the network and therefore the amount of current or voltage that passes through can be controlled.

The 8 resistors in the RP102PJ102CS Resistor Network can be combined in any combination to produce a desired resistance ratio. For example, two resistors of ratio 16 and 64 can be combined in series to create a resistance ratio of 1:80. Similarly, four resistors of ratio 4, 16, 32 and 64 can be combined in parallel to create a ratio of 1:128. By combining the resistors in various combinations, any desired ratio can be created, allowing designers to choose an exact ratio for their specific circuit requirements.

Conclusion

The RP102PJ102CS Resistor Network is an important tool for circuit designers that enables them to precisely control current and voltage in a circuit, depending on the desired characteristics. The 8 resistors in the network are precision components provided in predetermined ratios that can be combined to create any desired resistance ratio. This allows for the precise control of the current and voltage in low-noise preamplifiers, switching circuits, power supplies, logic circuits and other applications.
