LLMCG201208T8R0NG

Chip Ferrite Bead Overview

The LLMCG201208T8R0NG is a high-current ferrite bead inductor manufactured by Taiyo Yuden. It features an 0805 (2012 metric) surface-mount package with dimensions of 2.0 mm length, 1.2 mm width, and 0.8 mm height. The component provides an impedance of 8 Ohms at a test frequency of 100 MHz with a tolerance of 30%. It supports a maximum DC current of 4 A and has a maximum DC resistance of 7 mOhms. The device operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Designed for electromagnetic interference suppression in power lines
• Capable of handling high direct current loads
• Constructed as a wire-wound ferrite bead inductor

Chip Ferrite Bead Applications

• Power line EMI suppression
• Automotive electronic circuits
• Industrial equipment filtering

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'NT' or 'NG' against official datasheets, as these often denote tape-and-reel packaging variations rather than functional differences. Confirm RoHS compliance status directly from the manufacturer's documentation. Ensure the selected variant matches the required reel quantity specifications for automated assembly processes.

Chip Ferrite Bead Selection Notes

Select this component when designing circuits requiring significant current handling capability alongside noise attenuation. The 0805 footprint offers a balance between current capacity and board space efficiency. Verify that the 8-ohm impedance profile aligns with the target frequency spectrum of the interference being mitigated in the specific application design.

Chip Ferrite Bead Part Context

This part belongs to the LLMC/LLMG series of wire-wound ferrite bead inductors intended for power lines. Taiyo Yuden produces these components using proprietary raw materials and advanced technologies to ensure reliability. The series is characterized by high current ratings and low DC resistance, making it suitable for demanding environments.

Chip Ferrite Bead Replacement Considerations

Public sources suggest the FBMJ2125HL8R0NT as an alternate option. Note that this substitute utilizes a larger 0603-equivalent footprint compared to the 0805 package of the LLMCG201208T8R0NG. Mechanical re-design may be necessary if substituting this part.
