The component has a maximum DC resistance of 2.51 Ω and a saturation current rating of 390 mA. Designed for through-hole mounting, it operates within a temperature range of -55°C to +125°C. The physical dimensions are 5.72 mm in diameter by 14.48 mm in length.

Fixed Inductors Feature Summary

• Axial leaded construction for through-hole PCB integration
• Ferrite core design optimized for power applications
• Unshielded tubular structure for general-purpose use

Fixed Inductors Applications

• Power supply filtering circuits
• General-purpose inductive components
• Choke applications in electronic assemblies

Fixed Inductors Procurement Notes

Verify the specific RoHS compliance status, as sources indicate both compliant and non-compliant variants exist for this series. Confirm the exact DC resistance and saturation current ratings against the manufacturer's official datasheet for the specific manufacturing batch. Ensure the axial lead spacing matches the target PCB footprint requirements before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when a high-inductance value is required in an axial package format. The 330 µH value suits low-frequency filtering tasks. Consider the 390 mA saturation limit for circuit current constraints. The wide operating temperature range supports deployment in demanding environmental conditions where standard commercial-grade parts may fail.

Fixed Inductors Part Context

This part belongs to the API Delevan 2256R series of fixed inductors. The series offers various inductance values in a standardized axial package. The 'R' suffix typically denotes RoHS compliance in some contexts, but verification is required. The series is designed for robust performance in power electronics and signal conditioning applications.

Fixed Inductors Replacement Considerations

Cross-reference with other axial ferrite core inductors offering 330 µH ±5%. Verify that substitute parts meet or exceed the 2.51 Ω DCR and 390 mA Isat specifications. Ensure the replacement maintains the same 5.72 mm diameter and 14.48 mm length for mechanical compatibility.
