LSMGA201208T121RG

Chip Ferrite Bead Overview

The LSMGA201208T121RG is a surface-mount ferrite bead from the LSMG series, designed for high-current power line noise suppression. It features an 0805 (2012 metric) package with dimensions of 2mm length, 1.25mm width, and 0.85mm height. The component offers a nominal impedance of 120 ohms at 100MHz with a tolerance of ±25%. It supports a maximum DC current of 2.5A and has a maximum DC resistance of 32 milliohms. Operating temperatures range from -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides effective attenuation of radiated and conducted noise on power lines.
• Engineered for high-current applications with low DC resistance to minimize voltage drop.
• Compact 0805 footprint suitable for space-constrained surface-mount designs.

Chip Ferrite Bead Applications

• Power line noise suppression in portable electronic devices
• EMI filtering for DC power inputs in consumer electronics

Chip Ferrite Bead Procurement Notes

Verify that the specific order quantity meets the manufacturer's factory pack requirements, typically 4000 units per reel. Confirm RoHS compliance status and ensure the selected packaging type aligns with automated assembly capabilities. Cross-reference the impedance tolerance and current ratings against the specific circuit design requirements before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when high current handling up to 2.5A is required alongside significant impedance for noise reduction. The low DC resistance of 32 milliohms makes it suitable for power rails where efficiency is critical. Ensure the operating temperature range of -40°C to +125°C covers the environmental conditions of the target application.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the LSMG series by Taiyo Yuden, specialized for high-current power line applications. It addresses the growing need for compact EMI solutions in modern electronics. The 0805 package size balances performance with board space efficiency, making it a common choice for mobile and industrial power management circuits.

Chip Ferrite Bead Replacement Considerations

Check for direct substitutes within the same LSMG series or other 0805 ferrite beads offering similar 120-ohm impedance and 2.5A current ratings. Verify dimensional compatibility and thermal characteristics to ensure seamless integration without redesigning the PCB layout.
