4448-26L

Overview

The Delevan 4448-26L is a high-current coupled inductor from the 4448 series, designed for surface-mount technology (SMT) applications. It features a toroidal core construction with molded packaging to minimize electromagnetic interference. The component provides an inductance of 68 µH with a tolerance of ±15%. It exhibits a maximum DC resistance of 0.238 Ω and supports a maximum DC current of 1.1 A. The physical dimensions are approximately 13.5 mm by 13.5 mm with a height of 7.87 mm, suitable for PCB mounting.

Feature Summary

• High-current capability optimized for power filtering applications
• Molded toroidal construction for enhanced EMI suppression
• Surface-mount design for automated assembly integration

Applications

• Power supply input/output filtering
• DC-DC converter stages
• Data line filtering in electronic systems

Procurement Notes

Verify RoHS compliance status as listings indicate variations between leaded and unleaded versions. Confirm package quantity requirements, as factory pack quantities may vary by distributor. Ensure the specific suffix matches the required termination material and environmental rating for the target application.

Selection Notes

Select this component when high current handling and compact SMT footprint are required. Compare DC resistance and saturation current against circuit load demands. Consider the toroidal shape for superior magnetic shielding compared to open-core alternatives in dense PCB layouts.

Part Context

Part of the Delevan 4448 series of coupled inductors. This series includes variants with different inductance values and current ratings, such as the 4448-110M and 4448R-26L. The manufacturer specializes in high-reliability passive magnetic components for industrial and commercial electronics.

Replacement Considerations

The 4448R-26L is a related variant within the same series. Verify if the 'R' suffix denotes a specific RoHS-compliant or lead-free version that meets regulatory requirements for the end product.
