Fixed Inductors Procurement Notes
Verify the specific suffix 'F' indicates RoHS compliance as documented by the manufacturer. Confirm the package dimensions match the required PCB footprint. Ensure the selected variant matches the exact 22 µH inductance requirement. Cross-reference the datasheet for any recent updates to electrical specifications or thermal ratings before finalizing procurement orders.
Fixed Inductors Selection Notes
Select this component when magnetic shielding is required to reduce EMI in compact designs. The 1.9 A current rating suits moderate power applications. Verify that the 59.1 mΩ DC resistance meets efficiency targets. Consider the operating temperature range for environmental suitability. Compare against non-shielded alternatives if cost is a primary constraint.
Fixed Inductors Part Context
This part belongs to the CTSLF series of shielded power inductors manufactured by Central Technologies. The series offers various inductance values and current ratings. The CTSLF1045TF-220M specifically provides a balance of size and performance for space-constrained power electronics.
Fixed Inductors Replacement Considerations
