Fixed Inductors Procurement Notes

Verify the specific datasheet version to confirm thermal characteristics and detailed mechanical drawings. Ensure the supplier provides RoHS compliance documentation consistent with manufacturer standards. Cross-reference the part number suffixes to confirm exact tolerance and packaging variations if required for production.

Fixed Inductors Selection Notes

Select this component when a 22 µH inductance value is required with a high saturation current capability of 2.9 A. The low DCR of 0.05 Ω makes it suitable for efficiency-sensitive power stages. Consider the radial package size for PCB layout constraints.

Fixed Inductors Part Context

This part belongs to the CTRFB series of fixed inductors from Central Technologies. The series offers various inductance values tailored for power electronics. The 'F' suffix typically denotes specific tolerance or packaging attributes within the manufacturer's lineup, while '220K' indicates the 22 µH rating.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 22 µH inductance, 2.9 A saturation current, and 0.05 Ω DCR. Verify that alternative components support radial through-hole mounting and similar physical dimensions to ensure compatibility with existing footprints.
