LLMCA451611T900RG

Chip Ferrite Bead Overview

The LLMCA451611T900RG is a high-current ferrite bead from the TAIYO YUDEN LLMCA series, designed for surface-mount applications. It features an impedance of 90 Ω ±25% at a measuring frequency of 100 MHz. The component utilizes an 1806 (4516 Metric) case size and supports a rated current of 4A. Its low DC resistance of 14 mOhm minimizes power loss in power line filtering circuits.

Chip Ferrite Bead Feature Summary

• Engineered for high-current power line noise suppression
• Optimized for minimal insertion loss with low DC resistance
• Suitable for compact surface-mount assembly processes

Chip Ferrite Bead Applications

• Power supply input filtering
• DC-DC converter output noise reduction

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'RG' against the manufacturer's latest datasheet to confirm reel packaging and tape-and-reel specifications. Ensure the 1806 package dimensions align with your PCB footprint design. Confirm RoHS compliance status directly with the supplier documentation prior to final procurement approval.

Chip Ferrite Bead Selection Notes

Select this component when circuit requirements demand a 90 Ohm impedance at 100 MHz alongside a 4 Ampere current rating. The 1806 package provides a balance between thermal performance and board space efficiency. Compare the 14 mOhm DC resistance against alternative parts to ensure voltage drop constraints are met within the specific application environment.

Chip Ferrite Bead Part Context

This part belongs to the LLMCA series of high-current ferrite beads manufactured by TAIYO YUDEN. These components are specifically developed to address electromagnetic interference in modern electronic devices where space is limited but high current handling is essential. The series offers various impedance values within the same physical footprint.

Chip Ferrite Bead Replacement Considerations

Cross-reference with other 1806 ferrite beads offering similar 90 Ohm impedance and 4A current ratings. Verify that substitute components maintain compatible DC resistance and thermal characteristics to ensure equivalent circuit performance without redesigning the layout.
