CTMMP1808AF-R68M

Fixed Inductors Overview

The CTMMP1808AF-R68M is a shielded power inductor from Central Technologies, designed for surface-mount applications. It features a nominal inductance of 6.8 µH with a tolerance of ±20%. The component utilizes a ferrite core and is housed in an 1808 (4520 metric) package. Key electrical specifications include a maximum DC resistance of 260 mΩ, a saturation current rating of 2.2 A, and an RMS current rating of 2.2 A.

Fixed Inductors Feature Summary

• Shielded construction minimizes electromagnetic interference
• High current handling capability for power circuits
• Surface-mount design facilitates automated assembly

Fixed Inductors Applications

• DC-DC converter output filtering
• Power supply input stages
• General purpose power inductors

Fixed Inductors Procurement Notes

Verify the specific suffix 'R68M' corresponds to the 6.8 µH value during ordering. Confirm RoHS compliance status if required by project standards. Ensure the selected distributor provides official datasheets to validate the 260 mΩ DCR and 2.2 A current ratings against your circuit requirements.

Fixed Inductors Selection Notes

Select this component when a shielded inductor is required to reduce magnetic coupling in dense layouts. The 1808 footprint offers a balance between size and current capacity. Verify that the 2.2 A saturation current meets the peak load demands of the application without significant inductance drop.

Fixed Inductors Part Context

This part belongs to the CTMMP1808AF series of shielded power inductors. The series typically includes various inductance values ranging from low nanohenry to microhenry levels, all sharing the same 1808 package dimensions and shielding technology for consistent performance characteristics.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 1808 package, 6.8 µH inductance, and similar current ratings. Check competitor datasheets for equivalent shielded power inductors with comparable DCR and Isat specifications.
