Overview
The Delevan 4448R-112M is a coupled inductor from the 4448/R series, designed for surface mount technology (SMT) applications. It features a toroidal core construction with an 8 µH inductance per coil when connected in parallel and 32 µH in series. The component has a 20% tolerance and supports a maximum DC current of 3.5 A. Its maximum DC resistance is 19 mΩ. The physical dimensions are 13.71 mm in length, 13.71 mm in width, and 7.87 mm in height.
Feature Summary
- Dual-coil coupled inductor architecture suitable for power filtering
- Molded SMT package for automated PCB assembly
- Toroidal core design for efficient magnetic coupling
Applications
- DC-DC converter input/output filtering
- Power supply noise suppression circuits
- Signal transformer arrays in mixed-signal systems
Procurement Notes
Verify the exact part number suffix against manufacturer documentation to confirm electrical specifications and packaging type. Confirm RoHS compliance status as indicated in official datasheets. Ensure ordering quantities align with factory reel requirements specified by the supplier. Cross-reference distributor listings with API Delevan official catalogs to validate authenticity and lead times.
Selection Notes
Select this component for applications requiring dual-coupled inductance in a compact SMT footprint. Consider the 3.5 A current rating and low DCR for efficiency-sensitive designs. Verify that the 13.71 x 13.71 mm body size fits within the available board space constraints.
Part Context
This component belongs to the Delevan 4448/R series of coupled inductors. It is categorized under Arrays and Signal Transformers. The product is manufactured by API Delevan Inc. and is typically supplied in tape and reel packaging for high-volume surface mount production lines.
Replacement Considerations
Check for direct substitutes within the 4448R series, such as 4448R-110M or 4448R-122M, which share similar form factors but differ in inductance values. Ensure any replacement maintains compatible current ratings and physical dimensions.
