Introduction

Resistor Networks, Arrays are frequently used in many applications. In particular, RM062PJ105CS is a device with superior characteristics than most other resistors. This article will try to explain its application field and working principle.

Application Field of RM062PJ105CS

RM062PJ105CS is mainly used in wideband electronics, signal processing and high frequency applications. In wideband electronics, they are used to produce a wide range of operational amplifiers, band-pass amplifiers and more. In signal processing applications, the resistor network is used to connect multiple signals while still maintaining signal integrity. RM062PJ105CS can also raise the impedance of high frequency signals for better signal performance. Furthermore, they are also commonly used in the filter circuits to better adjust the frequency of input signal.

Working Principle

Internally, RM062PJ105CS comprises of two 2-terminal resistors network. Each 2-terminal resistor is connected in series. Thus, when the two resistors are connected in series, they form 3 terminals: 2 common terminals and 1 output terminal. The two terminals connected in series form the common terminal and the other terminal is the output terminal of the resistor network. The impedance of the resistor network is dependent on the selection of resistor values.

In order to achieve an adjustable resistance, each resistor can be connected to a digital potentiometer (or trimmer). By controlling the resistance of the potentiometers, the resistance of the entire resistor network can be changed. The resistor and trimmer is connected in such a way that the trimmer is connected in series with one of the resistors in each network.

Moreover, an adjustable resistor can also be connected in series between the two common terminals. This adjustable resistor is called a trim resistor. It is used to provide fine adjustment of the resistance of the resistor network. This configuration provides improved resolution compared to the potentiometer approach.

Conclusion

In conclusion, RM062PJ105CS is the most popular Resistor Networks, Arrays in use today. It is used in a variety of applications, especially in wideband electronics, signal processing and high frequency tailored applications. The network comprises of two 2-terminal resistors connected in series and can be adjusted through digital potentiometers or trim resistors.
