Resistor Networks, Arrays

Resistor networks are composed of individual resistors connected together in various configurations to create the desired electrical response for a given application. One widely used type of resistor network, AF122-FR-0717R8L, is a precision surface-mounted polyester film resistor array. The array has two rows of eight resistors with a 0.1Ω total resistance value. Built on a ceramic body and capable of withstanding up to 125°C, AF122-FR-0717R8L is a popular choice for applications requiring excellent temperature stability and reliability. Its small physical size and wide resistance range make it well-suited for high density designs, and its optimized formulation provides good pulse handling capabilities.The AF122-FR-0717R8L is designed to be used in a variety of applications, including automotive, industrial, military, and aerospace applications. It offers resistance values that provide good tolerance, temperature coefficient of resistance (TCR) tracking, and long-term stability. This resistor array is highly accurate, and the tight tolerances make it suitable for use in precision circuitry. Additionally, the resistor array is outfitted with a wide operating temperature range, making it a reliable choice for use in extreme temperature environments.The AF122-FR-0717R8L is a four terminal device, with eight resistors connected in two rows. Each row includes four resistors in parallel in order to achieve a total resistance value of 0.1Ω. The internal resistance of each resistor is 0.001Ω. The resistors are connected in series between the two rows, creating a bridge configuration. This creates a resistor array with two inputs and one output, allowing the current to flow in one direction, from one side of the bridge to the other.The AF122-FR-0717R8L is a low inductance, high stability resistor array that is suitable for use in many precision applications. Its high linearity and low noise performance make it ideal for noise sensitive circuits. It is also suitable for use in power circuits, as it is capable of handling high surge currents without impacting the performance of the circuit.The working principle of the AF122-FR-0717R8L is based on the Ohm\'s Law equation. Ohm\'s Law states that the current flowing through a resistor is equal to the voltage applied, divided by the resistance of the resistor. The resistor array is designed such that the total resistance between the two rows is 0.1Ω. When a voltage is applied to the terminal of the resistor array, the current flowing through the resistor is determined by dividing the applied voltage by the total resistance of the array. The AF122-FR-0717R8L is a useful tool in many industrial and automotive applications. Its precision, high temperature performance, and low inductance properties make it well-suited for use in noise sensitive circuits, automotive electronics, and power circuits. Its four-terminal design allows for the easy integration into a variety of circuit designs, and its wide operating temperature range ensures reliable operation in extreme temperatures. Its wide range of resistance values also makes it suitable for a variety of precision applications.
