LCMGA452525T102NG

Chip Ferrite Bead Overview

The LCMGA452525T102NG is a high-current ferrite chip bead manufactured by Taiyo Yuden, designed for surface-mount technology in the 1810 (4525 metric) package. It exhibits an impedance of 1 kOhms at a test frequency of 100 MHz with a tolerance of ±30%. The component supports a maximum DC current of 3 A and maintains a maximum DC resistance of 60 mOhms. It operates within a temperature range of -40°C to +125°C and features physical dimensions of 4.5 mm length, 2.5 mm width, and 2.8 mm height.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression for power lines through high-impedance characteristics at target frequencies.
• Engineered for high-current applications, supporting up to 3 A continuous DC operation without saturation.
• Features low DC resistance to minimize power loss and voltage drop in sensitive power distribution networks.

Chip Ferrite Bead Applications

• Power supply circuits requiring noise filtering on input or output lines
• Battery charger systems needing EMI suppression in high-current paths
• Voltage regulation modules where signal integrity must be maintained against high-frequency noise

Chip Ferrite Bead Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as availability may vary between cut tape, reel, or MouseReel formats. Confirm that the 1810 package dimensions align with your PCB footprint requirements. Ensure the 3 A current rating meets your circuit's peak load demands. Cross-reference the manufacturer part number with distributor codes to avoid substitution errors during procurement.

Chip Ferrite Bead Selection Notes

Select this component when designing power stages that require robust EMI filtering combined with high current handling capabilities. The 1 kOhm impedance at 100 MHz makes it suitable for suppressing common switching noise frequencies found in modern power electronics. Consider the low DC resistance to ensure minimal efficiency loss in the power path compared to higher-resistance alternatives.

Chip Ferrite Bead Part Context

This component belongs to the LCMG series of ferrite beads from Taiyo Yuden, specialized for high-current applications. It serves as a passive filter element in electronic assemblies, functioning similarly to resistive inductors at high frequencies while maintaining low resistance at DC. The 1810 package provides a balance between current capacity and board space efficiency.

Chip Ferrite Bead Replacement Considerations

Officially documented equivalent part numbers include FBMH4525HM102NT and LSMGA452525T102NG. These substitutes share similar electrical characteristics and package dimensions. Verify compatibility with specific application requirements before substitution, as minor differences in impedance curves or current ratings may exist between series.
