Resistor Networks, Arrays & the RF064PJ300CS

Resistor networks, or arrays, are composed of individual resistors that have been connected in a certain manner to create a component with unique electrical characteristics. The RF064PJ300CS is a 0.064 inch surface mount resistor network manufactured by Yageo, that consists of a series of resistors with each resistor having a resistance of 300 ohms. The application field and working principle of the Yageo RF064PJ300CS shall be the focus of this paper.

Principle of Operation

The RF064PJ300CS is a four-terminal surface mounted resistor network, composed of five paralleled resistors, each of which has a resistance of 300 ohms. When in operation, two pairs of terminals (pins) are connected to respective voltage sources, whilst the other two pins are connected to the load to be supplied with current.The electrical current passes through each one of the resistors in order to get from one voltage source to the other. The current must pass through each one of the resistors in the resistor network since in a parallel series of resistors, the current flowing through each resistor will remain constant, no matter how many resistors are in series. This is what is referred to as Kirchhoff’s Current Law.The voltage at the output is determined by the corresponding voltage at the input and the resistance of the resistors in the resistor network; this is known as Ohm’s Law and is given as:E = IRWhere:E - accumulated voltage at the output of the resistor networkI - current in each resistorR - resistance of each resistor In the case of the Yageo RF064PJ300CS, the total resistance of the resistor network would be 1.5k ohms and the output voltage at the output will be equal to the corresponding input voltage minus the product of the current and total resistance (1.5k).

Application Fields for the RF064PJ300CS

The Yageo RF064PJ300CS resistor network is used in a wide variety of applications, most of which require a precise level of control over the output voltage. The resistor network is able to provide an accurate output voltage due to the consistent resistance of each resistor in the array and also due to the precise manufacturing process which ensures that each resistor has a resistance of exactly 300 ohms.The RF064PJ300CS is often used in systems where the output voltage needs to be regulated such as motor controllers, lighting systems, power supplies, audio applications, and process controllers. The resistor network can also be used for level sensing, current sensing, and voltage dividing.The RF064PJ300CS is also often used in telecommunications systems such as modems, Ethernet cards, and Wi-Fi devices, where the resistor array is used to provide the necessary impedance matching between the transmitting and receiving antennas.The resistor network is also often used in automotive systems such as engine control units (ECUs), electronic stability systems (ESP), traction control systems (TCS), and climate control systems. The array is used in these systems to provide the necessary voltage regulation and current sensing.
