4448-06M

Overview

The Delevan 4448-06M is a coupled inductor from the 4448 series, designed for surface mount technology (SMT) applications. It features a toroidal core construction and provides an inductance of 1 µH with a tolerance of ±20%. The component supports a maximum DC current of 3.5 A and exhibits a maximum DC resistance of 9 mΩ. Its physical dimensions are 13.46 mm in length and width, with a height of 7.87 mm. The device utilizes SMD/SMT termination styles and is supplied in tape and reel packaging.

Feature Summary

• Dual-coil coupled inductor configuration for power filtering
• Toroidal core design for high current handling capabilities
• Surface mount package optimized for PCB integration

Applications

• DC-DC converter input/output filtering
• Power supply noise suppression circuits
• Signal transformer arrays in mixed-signal systems

Procurement Notes

Verify the specific manufacturer designation, as API Delevan components may be sourced under various brand names. Confirm RoHS compliance status directly with the supplier, as historical data indicates variations. Ensure the ordering quantity aligns with the factory pack quantity requirements specified by the distributor to avoid partial reel issues.

Selection Notes

Select this component when a compact, high-current coupled inductor is required for space-constrained designs. The 1 µH value suits moderate frequency switching applications. Compare the 9 mΩ DCR against circuit loss tolerances. Ensure the 3.5 A current rating exceeds the peak operational load to prevent saturation.
