EBMS201209A121

Overview

The EBMS201209A121 is a multilayer ferrite chip EMI suppressor manufactured by Max Echo Technology Corp. It is housed in an 0805 (2012 Metric) package and designed for signal line applications. The component exhibits an impedance of 120 Ohms at 100 MHz with a tolerance of 25%. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 200 mOhm. The device operates within a temperature range of -55°C to 125°C.

Feature Summary

• Multilayer construction for compact surface-mount integration
• Designed for effective electromagnetic interference suppression on signal lines
• Capable of handling specified DC bias currents without saturation

Applications

• Signal line filtering in electronic circuits
• EMI suppression in portable devices
• Noise reduction in high-speed data interfaces

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official datasheet to confirm impedance and tolerance specifications, as suffixes often denote critical electrical variations. Ensure the ordering part number matches the required 0805 package dimensions and operating temperature range. Cross-reference the DC resistance and current ratings with system requirements before procurement to avoid performance mismatches.

Selection Notes

Select this component when signal line noise suppression is required in space-constrained designs utilizing the 0805 footprint. The 300 mA current rating suits low-power signal paths rather than power delivery lines. Compare the 120 Ohm impedance profile against target noise frequencies to ensure adequate attenuation. Verify that the 200 mOhm DC resistance does not introduce unacceptable voltage drops in the specific circuit application.

Part Context

This part belongs to the EBMS-2012 series of multilayer ferrite chip beads from Max Echo Technology Corp. The series is engineered for EMI suppression in various electronic assemblies. The EBMS designation typically indicates signal line applications, distinguishing it from power line variants like the ACMS series which handle higher currents.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer for direct equivalents or verify compatibility with alternative suppliers based on identical impedance, current rating, and package dimensions.
