Overview
The Delevan 4448-34L is a coupled inductor from the 4448/R series, designed for surface-mount technology (SMD) applications. It features two coils with a parallel inductance of 200 µH and a series inductance of 800 µH, both having a tolerance of ±15%. The component supports a maximum DC current of 600 mA and exhibits a maximum DC resistance of 810 mOhms. Its molded toroidal construction measures 13.71 mm in length and width, with a height of 7.87 mm.
Feature Summary
- Molded SMT construction for robust surface-mount integration
- Dual-coil configuration supporting parallel or series connectivity
- Toroidal core design for efficient magnetic coupling
Applications
- High-current power supply filtering
- DC-DC converter input/output stages
- EMI suppression in data lines
Procurement Notes
Verify the specific suffix designation against the manufacturer's latest documentation to ensure correct electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging specifications to avoid handling discrepancies.
Selection Notes
Select this component when a compact, high-current coupled inductor is required for space-constrained PCB layouts. The 4448/R series offers a balance of low DC resistance and high current handling capabilities. Evaluate the thermal performance under maximum load conditions to ensure reliability within the specified operating temperature range.
Part Context
The 4448-34L belongs to the Delevan 4448/R series of coupled inductors. This series is characterized by its molded SMT package and toroidal core structure, providing consistent performance for power management applications. The part is manufactured by API Delevan, a specialist in passive components.
Replacement Considerations
Cross-reference with other 4448/R series variants such as 4448-32L or 4448-112M if different inductance values are acceptable. Verify pinout compatibility and physical dimensions before substituting with generic coupled inductors.
