Resistor Networks, Arrays

4309R-101-103 is a type of resistor network, also known as an array. It is a monolithic semiconductor component with multiple resistors, capacitors, or diodes all in one package. The size of this package is typically designed to save space for mounting on a printed circuit board. It can also provide enhanced electrical properties, such as improved temperature coefficient and increased frequency response. The primary application of resistor networks is to divide current in a circuit and provide a voltage division.

The 4309R-101-103 resistor network is a 9 pin component with four resistors, four diodes, and an LED. Each resistor in the device has a nominal resistance of 1k ohms and the device has a total resistance of 4k ohms. The LED is used to indicate a fault or an over current condition in the circuit and the four diodes are used to implement a diode-bridge configuration. This diode bridge allows the resistor network to act as a voltage divider in a circuit.

The working principle of the 4309R-101-103 resistor network is simple. When a voltage is applied across the device, the four resistors divide the voltage so that each resistor gets 1/4th of the applied voltage. Similarly, each one of the four diodes provides a forward voltage of 700mV. When the output voltage of one of the diodes exceeds the forward voltage of another diode, current moves through that particular diode and the other three diodes remain open. This is how the resistance of each resistor, and the total resistance of the device, is determined.

Additionally, the LED in the 4309R-101-103 resistor network has multiple application. This LED can be used to monitor the current in the circuit, to indicate a fault, or to indicate excessive current in the circuit. The four resistors can also be used in combination with the LED to provide the user with visual feedback about the current in the circuit.

The 4309R-101-103 resistor network is a versatile device that can be used in a variety of applications, including power management, voltage switching, and level shifting. It is a useful device for dividing voltage and it is especially handy in applications which require a high degree of accuracy or low power consumption. By using the four resistors and four diodes, users can easily control current in a circuit and can make sure that any changes do not affect the overall circuit design.
