Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official datasheets to ensure compatibility with design requirements. Confirm that the shielded SMD package matches the footprint constraints. Check RoHS compliance status if environmental regulations apply to the final product assembly process.

Fixed Inductors Selection Notes

Select this component when a 68 µH inductance with 10% tolerance is required for RF signal paths. Ensure the 111 mA current rating meets the operational load. The shielded type is suitable for dense layouts where crosstalk reduction is necessary compared to unshielded alternatives.

Fixed Inductors Part Context

This component belongs to the Delevan fixed inductor series designed for high-frequency applications. It utilizes a shielded core structure to contain magnetic fields. The SMD format allows for direct integration into printed circuit boards without through-hole mounting requirements.

Fixed Inductors Replacement Considerations

Cross-reference with other shielded SMD inductors offering 68 µH ±10% tolerance. Verify that substitute parts match the 4.14 x 3.38 x 3.56 mm dimensions and have comparable current ratings and self-resonant frequencies.
