LSMCA451611T900RG

Chip Ferrite Bead Overview

The LSMCA451611T900RG is a wire-wound ferrite bead inductor designed for power line applications. It features an impedance of 90 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 4 A. The component has a maximum DC resistance of 14 mOhms with a tolerance of ±25%. It operates within a temperature range of -40°C to +125°C. The physical dimensions are 4.5 mm in length, 1.6 mm in width, and 1.1 mm in height, corresponding to the 1806 (4516 metric) package.

Chip Ferrite Bead Feature Summary

• Wire-wound construction for high-current power line filtering
• High saturation current capability up to 4 A
• Low DC resistance for minimal signal loss
• Shielded design to reduce electromagnetic interference

Chip Ferrite Bead Applications

• Power supply output filtering
• DC-DC converter noise suppression
• High-current digital circuit decoupling
• EMI suppression on power lines

Chip Ferrite Bead Procurement Notes

Verify the specific ordering suffix and packaging configuration against official Taiyo Yuden documentation before purchase. Confirm that the required impedance tolerance and current ratings align with the target application's electrical requirements. Ensure compatibility with surface-mount assembly processes given the 1806 package dimensions. Cross-reference part numbers with any designated alternate components if availability is constrained.

Chip Ferrite Bead Selection Notes

Select this component when a 90 Ohm impedance at 100 MHz is required for high-current power rails. The 4 A current rating makes it suitable for main power distribution paths where lower impedance beads would saturate. Consider the 14 mOhm DC resistance impact on voltage drop. The 1806 footprint offers a balance between current handling and board space compared to smaller packages.

Chip Ferrite Bead Part Context

This part belongs to the LSMC series of wire-wound ferrite beads from Taiyo Yuden. The series is characterized by its ability to handle high direct currents while providing effective high-frequency noise attenuation. The LSMC series is widely used in consumer electronics and industrial equipment for power integrity management.
