EBMS201209B202

Overview

The EBMS201209B202 is a multilayer ferrite chip bead manufactured by Max Echo, designed for EMI suppression in signal lines. It features an 0805 (2012 Metric) surface-mount package with dimensions of 2.0mm x 1.25mm and a maximum height of 0.9mm. The component provides an impedance of 2 kOhms at 100 MHz and supports a maximum current rating of 200mA. Its DC resistance is limited to a maximum of 400mOhm. The device operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Designed specifically for high-impedance signal line filtering applications
• Capable of handling rated currents up to 200mA with low DC resistance

Applications

• Signal line noise suppression in electronic circuits
• EMI filtering for portable devices
• High-frequency circuit protection

Procurement Notes

Verify the specific ordering suffixes such as TR, CT, or DKR to ensure correct packaging formats including tape and reel or cut tape. Confirm that the 0805 footprint matches the target PCB design. Ensure the 200mA current rating and 2kOhm impedance specifications align with the system's signal integrity requirements before finalizing procurement orders.

Selection Notes

Select this component when high attenuation is required for signal lines compared to standard power rail beads. The 2kOhm impedance at 100 MHz distinguishes it from lower impedance variants like the EBMS201209A series. Consider the 0805 package size for space-constrained designs requiring robust EMI performance without excessive physical volume.

Part Context

This part belongs to the EBMS series of multilayer ferrite chip beads produced by Max Echo Technology Corp. The series includes various impedance ratings and current capabilities tailored for different frequency ranges and circuit loads. The EBMS201209B202 represents a high-impedance variant within the 0805 form factor lineup.

Replacement Considerations

Potential parameter-equivalent substitutes include Pulse Electronics BBGK00160808121Y00, Cal-Chip Electronics FB160808T-121Y-S, and TDK MMZ1608B121CTAH0. Verify impedance curves and current ratings match the original design requirements before substitution.
