Fixed Inductors Procurement Notes

Verify the specific suffix 'J' indicates the required 5% tolerance and 1.5 mH value against official datasheets. Confirm RoHS status as availability varies by manufacturing batch. Ensure the axial lead spacing matches the target PCB footprint before ordering. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Fixed Inductors Selection Notes

Select this component when a 1.5 mH inductance with 5% precision is required for power handling. The 0.178 A current rating dictates suitability for low-to-medium power stages. The axial package requires sufficient board clearance for the 14.48 mm length. Verify thermal constraints align with the specified operating temperature range.

Fixed Inductors Part Context

This part belongs to the Delevan 2256/R series of axial lead power inductors. The series offers various inductance values sharing identical physical dimensions and mounting styles. The 'R' designation typically denotes the series family, while the numeric code specifies the inductance value. These components are engineered for robust performance in industrial and commercial power electronics.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 1.5 mH inductance, 5% tolerance, and 0.178 A current rating. Axial leaded power chokes with identical 14.48 mm x 5.72 mm dimensions ensure mechanical compatibility. Verify that alternative manufacturers offer comparable DC resistance and saturation characteristics.
