Fixed Inductors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm exact electrical tolerances and packaging variations. Ensure the procurement channel provides authentic components from Central Technologies to guarantee performance reliability and compliance with specified thermal and electrical ratings.

Fixed Inductors Selection Notes

Select this component when a 3.3 µH inductance value is required with a ±20% tolerance. Consider the 20 mOhm DCR for efficiency requirements and the 79 MHz self-resonant frequency for high-frequency operation limits. Validate that the through-hole package fits the target board layout constraints.

Fixed Inductors Part Context

This part belongs to the CT622LYF series of radial leaded fixed inductors. It shares the same physical form factor and mounting style as other variants in the series, differing primarily in inductance values and associated electrical characteristics such as saturation current and DC resistance.

Fixed Inductors Replacement Considerations

Cross-reference with other 3.3 µH radial inductors ensuring matching DCR, tolerance, and temperature ratings. Verify pin compatibility and mechanical dimensions before substituting with generic equivalents.
