Power Line Filter Modules Procurement Notes

Verify the specific suffix G125 against official TDK/EPCOS documentation to confirm the exact current and voltage ratings. Ensure the ordering code matches the required physical dimensions and mounting style. Cross-reference certification marks such as UL and VDE with the target market requirements before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this component when a single-phase filter is required for circuits operating up to 25 A and 250 V. Consider the 660 µH inductance value for the necessary attenuation characteristics. Verify that the panel mount form factor fits the available enclosure space and that the thermal properties of the metal case suit the installation environment.

Power Line Filter Modules Part Context

This part belongs to the SIFI-A series of two-line filters from EPCOS (TDK). The series offers various current ratings from 1 A to 20 A, though this specific variant handles 25 A. These filters are designed for normal insertion loss and are commonly used in power supplies and industrial control systems requiring robust EMI suppression.

Power Line Filter Modules Replacement Considerations

Consult official TDK replacement guides for direct substitutes within the B84111 series. Verify that any alternative maintains the 25 A rating, 660 µH inductance, and compatible mounting dimensions.
