Resistor Networks, Arrays

AF124-JR-070RL is an advanced resistor array with two separate resistors in a standard 8-pin package. This resistor array is designed to reduce the total size of the application and to simplify the manufacturing process. The AF124-JR-070RL is especially suitable for applications where space is a constraint or where there are large ripples or parasitic effects on the current.

Application Field

The AF124-JR-070RL is designed for a wide range of applications, such as automotive electronics, home appliance, wireless power transmission, video analytics, LED lighting, consumer electronics, and telecommunications applications. Its compact size makes it suitable for use in crowded or confined areas, and the two separate resistors allow for better signal filtering in noisy environments.

The AF124-JR-070RL is also suitable for power management applications, such as in battery power management, solar power conversion, and power control for renewable energy systems. Its low-resistance value provides improved performance and higher efficiency in these systems. Additionally, it can be used in audio systems for improved sound quality.

Working Principle

The AF124-JR-070RL is composed of two identical resistors, each having a resistance of 0.7Ω. When these resistors are connected in parallel (i.e. in an OR circuit configuration), the total resistance of the network is 0.35Ω. This network configuration ensures that current flows freely between the two resistors, with a very small voltage drop across each resistor.

The AF124-JR-070RL operates in two different modes, depending on the current level. When the current is low (less than 100mA), the resistors are in parallel, offering maximum current flow and minimum voltage drop. When the current is high (more than 100mA), the resistors are in series, offering maximum voltage drop and minimum current flow.

The two-resistor and series-parallel combination of the AF124-JR-070RL makes it ideal for applications where a low-resistance value and high-current capability are required. Its low internal resistance also ensures improved power conversion efficiency and improved system stability in low-volume applications.

Conclusion

The AF124-JR-070RL is a versatile two-resistor network in an 8-pin package. Its compact size makes it ideal for a wide range of applications, from automotive and home appliance electronics to telecommunications, LED lighting, and audio systems. Its low total resistance and two-resistor configuration ensures improved current and voltage levels, higher efficiency, and improved system stability.
