4448R-124L

Overview

The Delevan 4448R-124L is a coupled inductor from the 4448/R series, designed for surface mount technology (SMT) PCB mounting. It features a toroidal core constructed from ferrous alloy material. The component provides a series inductance of 50 µH with a tolerance of 15% and a parallel inductance of 200 µH. It supports a maximum DC current of 1.5 A and has a maximum DC resistance of 0.111 Ohms. The device is classified as an unshielded power inductor.

Feature Summary

• Surface mount toroidal design for automated PCB assembly
• Coupled inductor configuration with specified series and parallel inductance values
• Ferrous alloy core construction for high current handling capabilities

Applications

• Data line filtering applications
• Power supply circuitry requiring coupled inductance
• Signal transformer circuits

Procurement Notes

Verify the specific suffix designation to ensure correct inductance and tolerance specifications, as variations exist within the 4448/R family. Confirm RoHS compliance status and moisture sensitivity classification prior to integration into the manufacturing process. Cross-reference the manufacturer datasheet for precise mechanical dimensions and thermal characteristics to ensure compatibility with the target PCB layout and operating environment requirements.

Selection Notes

Select this component when a surface mount coupled inductor with a 50 µH series value and 1.5 A current rating is required. The unshielded toroidal design suits applications where magnetic interference is manageable. Ensure the PCB footprint accommodates the SMD package dimensions and that the operating temperature range aligns with the system's environmental constraints.

Part Context
