Fixed Inductors Procurement Notes
Verify the specific part number suffix to confirm tolerance ratings. Ensure the required saturation and rated currents align with circuit design specifications. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Cross-reference datasheet electrical parameters against actual application loads.
Fixed Inductors Selection Notes
Select this component based on its 390 µH inductance value and physical axial dimensions. Consider the 0.25 Ω DC resistance impact on circuit efficiency. Evaluate the 1.8 A saturation limit against peak current requirements. Compare alternative values within the CTH7F series for different filtering needs.
Fixed Inductors Part Context
This component belongs to the CTH7F series of general-purpose power line chokes from Central Technologies. The series offers a wide range of inductance values from 3.9 µH to 18,000 µH. All variants share similar axial packaging and core materials, providing consistent performance characteristics across the product line.
Fixed Inductors Replacement Considerations
Direct substitutes include other CTH7F series parts with matching inductance and tolerance. Verify that replacement components meet the same 2 MHz self-resonant frequency requirement. Ensure physical footprint compatibility for existing PCB layouts.
