Fixed Inductors Procurement Notes

Verify the specific datasheet version to confirm terminal plating details and exact physical dimensions. Ensure that the 250 mA current rating aligns with the thermal requirements of the target application environment. Confirm compliance with relevant environmental directives before final integration into the product design.

Fixed Inductors Selection Notes

Select this component when an unshielded axial inductor with 8.2 mH inductance is required for low-frequency power line applications. Consider the 6.32 Ohm DC resistance impact on circuit efficiency. Verify that the 250 mA current limit meets the peak load demands without causing saturation or excessive heating during operation.

Fixed Inductors Part Context

This part belongs to the CTH8F series of fixed inductors from Central Technologies. The series includes various inductance values ranging from microhenries to millihenries, all sharing similar axial leaded packaging and general-purpose characteristics. This specific model represents the higher inductance end of the standard power line choke lineup.

Fixed Inductors Replacement Considerations

Cross-reference with other 8.2 mH axial inductors from different manufacturers if supply constraints exist. Ensure equivalent current ratings and DC resistance values are maintained to prevent performance degradation in existing circuit designs.
