LCMGA452525T162NG

Chip Ferrite Bead Overview

The LCMGA452525T162NG is a high-current ferrite chip bead manufactured by Taiyo Yuden, designed for power line noise suppression. It features an impedance of 1.6 kOhms at a test frequency of 100 MHz and supports a maximum DC current of 2 A. The component has a maximum DC resistance of 130 mOhms with a tolerance of 30%. Housed in an 1810 (4525 metric) surface-mount package measuring 4.5 mm x 2.5 mm x 2.5 mm, it operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression on power lines through high-impedance characteristics at target frequencies.
• Engineered for high-current applications, maintaining performance under significant DC bias conditions up to 2 A.
• Constructed as a shielded single-element device to minimize external magnetic field interference.

Chip Ferrite Bead Applications

• Power supply input filtering in portable electronic devices
• Noise suppression on data bus lines requiring high current handling
• EMI mitigation in automotive-grade electronic modules

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'NG' against the manufacturer's latest datasheet to confirm compliance with RoHS3 standards and material composition. Ensure the ordering quantity matches the standard factory pack size of 1000 units or available cut-tape options. Confirm that the 1810 footprint aligns with the PCB design guidelines for thermal management during soldering processes.

Chip Ferrite Bead Selection Notes

Select this component when circuit requirements demand a ferrite bead capable of handling 2 A continuous DC current while providing 1.6 kOhms attenuation at 100 MHz. The 1810 package offers a balance between current capacity and board space. Consider the low DCR of 130 mOhms to minimize voltage drop and power loss in sensitive power rails compared to higher-resistance alternatives.

Chip Ferrite Bead Part Context

This part belongs to the LCMG series of wire-wound ferrite beads from Taiyo Yuden, specifically optimized for power line applications. Unlike standard ceramic types, these components utilize wire-wound technology to achieve superior high-current performance. The series is distinct from the FBMH series, which shares similar electrical parameters but may differ in shielding construction or manufacturing origin.

Chip Ferrite Bead Replacement Considerations

The FBMH4525HM162NT is documented as a suggested alternate with identical electrical specifications. Verify pin compatibility and mechanical dimensions before substitution. Other LCMG series variants with different impedance values are not direct replacements.
