LMMGA201208T331RG

Chip Ferrite Bead Overview

The LMMGA201208T331RG is a wire-wound ferrite bead inductor from the LMMC/LMMG series, designed for power line applications. It features a 0805 (2012 Metric) surface-mount package with dimensions of 2.0mm x 1.25mm x 0.8mm. The component provides an impedance of 330 Ohms at 100 MHz and supports a maximum DC current of 1.8A. Its maximum DC resistance is 80 milliohms. It operates within a temperature range of -40°C to +125°C and complies with RoHS standards.

Chip Ferrite Bead Feature Summary

• Wire-wound construction for stable performance on power lines
• High current handling capability suitable for dense circuit designs
• Compact 0805 footprint for space-constrained layouts

Chip Ferrite Bead Applications

• Power supply filtering in portable electronics
• Noise suppression in medical device circuits
• EMI reduction in automotive infotainment systems

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'RG' against the manufacturer's latest datasheet to confirm packaging and material compliance details. Ensure the ordering quantity aligns with standard reel sizes. Cross-reference the Mouser and DigiKey part numbers for accurate availability status before finalizing procurement plans.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity is required alongside significant impedance at 100 MHz. The 0805 package offers a balance between current handling and board space efficiency compared to smaller footprints. Verify that the 1.8A rating meets the peak load requirements of the target power rail.

Chip Ferrite Bead Part Context

This part belongs to Taiyo Yuden's LMMC/LMMG series, which are specialized wire-wound ferrite beads intended for medical devices and other sensitive applications. The series emphasizes stability and high current tolerance, distinguishing it from standard chip ferrite beads used primarily for signal integrity.

Chip Ferrite Bead Replacement Considerations

The FBMH1608HM331-T is a listed substitute but utilizes a smaller 0603 package with lower current ratings. Verify that the reduced physical size and 1.2A limit are acceptable for the application before substitution.
