LSMCC201208T420RG

Chip Ferrite Bead Overview

The LSMCC201208T420RG is a shielded ferrite chip bead from the TAIYO YUDEN LSMC series, designed for high-current applications. It features an 0805 (2012 metric) surface-mount package with dimensions of 2 mm length, 1.25 mm width, and 0.85 mm height. The component provides an impedance of 42 ohms at a test frequency of 100 MHz, with a tolerance of ±25%. It supports a maximum DC current of 4 A and has a maximum DC resistance of 8 mOhms. The device operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• High current handling capability suitable for power line filtering
• Compact 0805 footprint for space-constrained PCB layouts

Chip Ferrite Bead Applications

• Power supply output filtering
• DC-DC converter noise suppression
• High-speed digital signal line EMI reduction

Chip Ferrite Bead Procurement Notes

Verify the specific suffix and impedance value against the target design requirements. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before integration into production. Ensure the selected package size matches the PCB land pattern specifications.

Chip Ferrite Bead Selection Notes

Select this component when a compact ferrite bead with high current capacity is required for EMI suppression in power circuits. The 42-ohm impedance at 100 MHz targets specific noise frequencies. Compare the 4 A current rating against peak load conditions to prevent saturation or excessive heating during operation.

Chip Ferrite Bead Part Context

This part belongs to the LSMC series of high-current ferrite beads manufactured by TAIYO YUDEN. The series is characterized by its shielded structure and low DC resistance, making it distinct from standard unshielded ferrite chips. It serves as a passive component for noise control in modern electronic devices requiring robust power integrity.

Chip Ferrite Bead Replacement Considerations

The FBMJ2125HS250NT is listed as a suggested alternate part number by Mouser Electronics. Verify electrical parameters such as impedance and current rating before substitution.
