Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Central Technologies documentation to ensure authenticity. Confirm that the required inductance value and current ratings align with your circuit design specifications before procurement. Check for RoHS compliance requirements if applicable to your project standards.

Fixed Inductors Selection Notes

Select this component when an unshielded axial inductor is required for power line applications. Ensure the 330 µH inductance and 400 mA current handling meet the system's electrical demands. Consider the through-hole package constraints and physical dimensions of 15.3 x 7.37 mm for PCB layout compatibility.

Fixed Inductors Part Context

This component belongs to the CTH7F series of fixed inductors from Central Technologies. The series includes various inductance values such as 33 µH and 330 µH, all sharing similar axial packaging and through-hole mounting characteristics. These components are designed for general electronic applications requiring reliable passive filtering.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 330 µH inductance, axial package, and similar current ratings. Verify DCR and self-resonant frequency specifications to ensure equivalent performance in the target application.
