4448R-128L

Overview

The Delevan 4448R-128L is a non-shielded two-coil inductor array designed for surface-mount technology. It features an inductance of 100 µH with a tolerance of ±15%. The component has a maximum DC resistance (DCR) of 303 mΩ and supports a maximum DC current of 920 mA. When configured in series, the total inductance reaches 400 µH. The physical dimensions are 13.5 mm by 13.5 mm, with a height of 7.87 mm. It utilizes SMD/SMT termination styles for PCB mounting.

Feature Summary

• Non-shielded dual-coil architecture for flexible circuit integration
• Surface-mount design compatible with automated assembly processes
• Configurable series or parallel operation for varying impedance requirements

Applications

• Precision signal processing circuits
• Power supply filtering applications
• General-purpose electronic assemblies requiring compact inductive components

Procurement Notes

Verify the specific suffix 'L' against the manufacturer's official documentation to confirm lead times and availability status. Ensure that the RoHS compliance status matches your project requirements. Confirm that the package dimensions align with your PCB footprint design before finalizing procurement orders.

Selection Notes

Select this component when a dual-coil configuration is required in a compact surface-mount form factor. Consider the 303 mΩ DCR and 920 mA current rating to ensure adequate performance for the target application. Evaluate whether the non-shielded nature impacts nearby sensitive signals in the layout.
