Fixed Inductors Procurement Notes

Verify the specific manufacturing date code and lot traceability upon order confirmation. Ensure that the axial lead form factor matches the target PCB layout requirements. Confirm that the 130 mA current rating and 5.4 Ohm resistance values are sufficient for the intended circuit load conditions before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when a general-purpose axial inductor with 2.7 mH inductance is required for power line applications. Consider the 130 mA current limit and 5.4 Ohm resistance to ensure compatibility with the circuit's voltage drop and thermal constraints. Verify that the unshielded design does not interfere with nearby sensitive components due to potential magnetic field emission.

Fixed Inductors Part Context

This part belongs to the CTH7F series of power line chokes manufactured by Central Technologies. The series offers a wide range of inductance values from 3.9 µH to 18,000 µH, all utilizing an axial package style. The suffix 'K' indicates a standard ±10% tolerance for the inductance value across the product line.

Fixed Inductors Replacement Considerations

Direct substitutes include other 2.7 mH axial power line inductors with similar current ratings and resistance values. Cross-reference with Central Technologies CTH7F-272K equivalents from other manufacturers ensuring identical package dimensions and electrical specifications.
