4448R-06M

Overview

The Delevan 4448R-06M is a coupled inductor array featuring two coils with a toroidal core construction. It provides an inductance of 1 µH when connected in parallel and 4 µH when connected in series, with a tolerance of 20%. The component supports a maximum DC current of 7 A and exhibits a maximum DC resistance of 9 mOhms. Designed for surface mount technology (SMT) PCB mounting, it operates within a temperature range of -55°C to 125°C.

Feature Summary

• Toroidal core design for efficient magnetic coupling
• Dual-coil configuration supporting series or parallel connectivity
• High-current capability suitable for power applications

Applications

• DC-DC converter circuits
• Power supply filtering
• Signal processing arrays

Procurement Notes

Verify the specific suffix 'R' against manufacturer documentation to confirm package and electrical specifications. Ensure compatibility with SMT reflow processes. Confirm RoHS compliance status as indicated by the supplier data. Validate pinout alignment with target PCB footprint before integration.

Selection Notes

Select this component for designs requiring coupled inductance in a compact SMT form factor. The choice depends on the required inductance value (1 µH parallel vs. 4 µH series) and the 7 A current rating. Consider the unshielded nature for layout spacing requirements.
