Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Central Technologies documentation to confirm electrical parameters. Ensure compatibility with automated assembly processes regarding axial lead spacing. Confirm RoHS compliance status using the latest datasheet revision. Validate thermal performance requirements against the specified operating temperature range before integration into final designs.

Fixed Inductors Selection Notes

Select this component when a compact, shielded axial inductor is required for low-current applications. The 180 µH value suits intermediate frequency filtering needs. Consider the 4.4 Ohm DC resistance for voltage drop calculations. The 135 mA rating defines the continuous current limit. Evaluate space constraints as the molded package offers a small footprint compared to unshielded alternatives.

Fixed Inductors Part Context

This component belongs to the CTS3F series of fixed inductors from Central Technologies. The series provides various inductance values in a consistent axial molded form factor. These components are designed for general electronic applications requiring reliable passive filtering. The series emphasizes compact size and shielding effectiveness for modern circuit board layouts.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 180 µH inductance, 135 mA current rating, and axial package dimensions. Verify that alternative manufacturers offer equivalent shielding and DC resistance specifications. Cross-reference terminal plating and temperature ratings to ensure environmental compatibility.
