Fixed Inductors Procurement Notes

Verify the specific suffix 'K' confirms the ±10% tolerance requirement for your circuit design. Ensure the axial lead spacing matches your PCB footprint, as the component measures 29.2 mm in length. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Cross-reference the 322 mA current rating against peak load conditions to prevent saturation.

Fixed Inductors Selection Notes

Select this component when a shielded axial inductor is required to reduce noise coupling in sensitive analog or digital circuits. The 100 µH value suits moderate frequency filtering tasks. Consider the 2.3 Ohm DC resistance impact on voltage drop in low-voltage power paths. The molded package offers mechanical robustness compared to unshielded alternatives.

Fixed Inductors Part Context

This part belongs to the CTS4F series of shielded axial inductors from Central Technologies. The series utilizes amorphous cores and molded encapsulation to provide consistent inductance values with reduced external magnetic field emission. Similar parts in the family vary primarily in inductance values and current ratings while maintaining the same axial form factor.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 100 µH inductance, ±10% tolerance, and axial package dimensions. Verify that alternative components meet or exceed the 322 mA current rating and 2.3 Ohm DC resistance limits. Ensure the replacement also offers shielded construction to maintain EMI performance standards.
