Working Principle

4309R-101-202LF is a three resistor network. The three resistors form the topology of a standard voltage divider circuit. When a current passes through one of the resistors, the voltage of the current is divided among the other two resistors depending on the resistance of each resistor. This voltage division helps to deliver precise control of current in the circuit. In addition, the resistors have a built-in feature to provide positive temperature coefficient which helps to compensate the changes in temperature. The resistor network consists of a high temperature stable metal film resistor island, an organic substrate, and two insulated, spaced apart PCB terminals. The island is embedded in the substrate consisting of solder-mask to provide protection. The terminals are used to provide power and ground connections.

Conclusion

4309R-101-202LF is a specialized application field resistor network offering excellent thermal characteristics suitable for various applications. The unique electrical properties of the resistors make it an ideal choice for power sampling, sensing, filtering, and other signal conditioning applications. The working principle of the resistor network consists of two isolated PCB terminals and a high temperature stable metal film resistor island embedded in the substrate with a solder-mask on top. The voltage division across the two resistors helps to deliver precise control of current in the circuit. Thus 4309R-101-202LF is an ideal choice for applications such as switch mode power supplies, inverters, converters, and other power supply related circuits.
