It features a toroidal core construction with two coils, providing an inductance of 68 µH at a tolerance of ±15%. The component exhibits a maximum DC resistance of 0.238 Ω and supports a rated current of 1.1 A. Its physical dimensions are 13.5 mm by 13.5 mm with a height of 7.87 mm, utilizing SMD/SMT termination styles for PCB mounting.
Feature Summary
- High-current capability suitable for demanding power applications
- Toroidal core design for efficient magnetic coupling
- Molded surface-mount construction for automated assembly
Applications
- Power supply filtering circuits
- DC-DC converter input/output stages
- High-current signal processing systems
Procurement Notes
Verify the specific suffix (L vs M) against the manufacturer's latest datasheet to confirm exact electrical tolerances and current ratings, as variations exist within the 4448R family. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements to avoid handling discrepancies.
Selection Notes
Select this component when a compact, high-current coupled inductor is required for space-constrained designs. The 68 µH value and 1.1 A rating define its operational limits. Compare the 0.238 Ω DCR against system efficiency targets. Ensure the 13.5 mm footprint fits the PCB layout constraints. Consider thermal management requirements given the high-current operation and molded package characteristics.
Part Context
This part belongs to the Delevan 4448/R series of coupled inductors. The series is characterized by toroidal cores and high-current capabilities. The 4448R-26L specifically denotes the 68 µH variant within this lineup. These components are engineered for robust performance in power electronics, distinguishing them from standard single-coil power inductors through their coupled architecture.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative manufacturers' high-current coupled inductors based on matching inductance, current rating, and physical footprint dimensions.
