This component is designed for a wide range of applications, and provides improved reliability, and improved performance from higher quality resistors.

Overview of the AF122-FR-0730K1L

The AF122-FR-0730K1L is a 32-pin full-wave bridge quad-resistor network array in a single, compact package. It can handle high-current applications with a maximum power rating of 1W. The array is composed of four separate resistors, each with a resistance range from 0.1Ω to 500kΩ, and an operating temperature range of -55℃ to +125℃.

The quad-resistor array is also equipped with full protection from transient voltage surges or spikes, and features an isolated package that isolates each resistor from its neighboring resistors, which further reduces electrical noise. The array also features an EMI/RFI shielding to prevent radio frequency interference.

Applications of the AF122-FR-0730K1L

The AF122-FR-0730K1L is ideal for a range of applications, including power supply circuits, signal line impedance matching, AC/DC conversion circuits, and precision voltage dividers. It is also used to create high-precision current sense circuits or voltage-sensing circuits that are highly sensitive and require low noise integrated into a small size. As a quad-resistor array, it is an efficient solution for any application requiring multiple resistors in one package.

In addition, the AF122-FR-0730K1L is also suitable for use in industrial and automotive systems, as it is UL/CSA approved. Safety applications, where resistors are used to protect circuits or sensitive components from excessive voltages, are another ideal use for the AF122-FR-0730K1L.

Working Principle of the AF122-FR-0730K1L

The AF122-FR-0730K1L component works based on the idea of Ohm’s Law, a scientific formula which states that the current flowing through a resistor is equal to the Voltage divided by the resistance. Each of the four resistors in the AF122-FR-0730K1L works independently, and the voltage across each resistor is set independently using a set of external resistors and capacitors as voltage dividers. This produces a total current in the circuit that is equal to the sum of the individual resistor current contributions.

The AF122-FR-0730K1L works by dividing the current into the four resistors of the array in a variety of ways. These include series combination, parallel combination, or by creating a voltage divider composed of two series resistors. By varying the external resistors and the resistance to an external load, the specific resistive divider circuits can be programmed, allowing for high resolution, low noise, and precise control of output currents in the circuit.
