Resistor Networks, Arrays

RPS102PJ204CS is a resistor network developed by KOA Speer. It is a 4-resistor array composed of 4 individual SMT resistors in a single package. It is used for applications requiring higher power rating than a single resistor can provide, including pulse handling, power supply voltage regulation, and current sensing. Many industrial, automotive, semiconductor, and military applications need the high power and accuracy that this network provides. RPS102PJ204CS consists of 1/8 watt surface-mount resistors in 0402 package, providing up to 1 watt of power dissipation.

Applications

RPS102PJ204CS is often used in applications involving voltage regulation, motor control, power supply voltage regulation, and current sensing. It can be used as a voltage-level translator, voltage limiter, voltage regulator, or current limiter in any of these applications. In industrial applications, it can be used for high-power pulse handling and voltage regulating. It can also be used as an audio amplifier decoupling circuit or a voltage reference in motor control circuits. In automotive applications, it can be used for voltage level shifting, current limiting, power control, and voltage regulation. In military and aerospace applications, this network is used for protection of sensitive circuits from high voltage fluctuations.

Working Principle

The RPS102PJ204CS is a 4-resistor network where each individual resistor offers resistance of 33 Ohms. Putting all four resistors in parallel provides a total of 8.25 Ohms resistance which is equal to the equivalent resistance of a single resistor having the same resistance level. This allows current to be divided equally between all four resistors. When the RPS102PJ204CS is placed in series with a load, current is distributed in a single direction through the load and resistors. The resistors absorb current and dissipate it as thermal energy, thus regulating the current flowing through the load.

Conclusion

RPS102PJ204CS is an array of four SMT resistors in one package. It is used for applications requiring higher power rating than a single resistor. It is suitable for motor control, voltage regulation, audio amplifier decoupling, and voltage level shifting. It has a total resistance of 8.25 Ohms and can provide up to 1 watt of power dissipation. When placed in series with a load, the network regulate the current flow through the load by dissipating excess energy as heat.
