EBMS201209B222

Overview

The EBMS201209B222 is a multilayer ferrite chip bead manufactured by Max Echo, designed for EMI suppression in signal lines. It operates within an impedance range of 2.2 kOhms at 100 MHz and supports a maximum current rating of 200mA with a DC resistance of 500mOhm. The component utilizes a 0805 (2012 Metric) surface-mount package, ensuring compatibility with standard PCB layouts. It functions effectively across a wide temperature range from -55°C to 125°C, providing reliable noise filtering for high-frequency applications without significant signal degradation.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Single signal line configuration optimized for compact circuit designs
• Surface-mount technology compatible with automated assembly processes

Applications

• High-speed digital signal line filtering
• Power supply noise attenuation in portable devices
• EMI suppression in communication modules

Procurement Notes

Verify the specific impedance tolerance and current derating curves against your application requirements before finalizing the design. Confirm that the 0805 footprint matches your PCB silkscreen and copper pad layout. Ensure the supplier provides RoHS3 compliance documentation as specified in the manufacturer's standards. Check for any moisture sensitivity level restrictions during storage and handling procedures.

Selection Notes

Select this component when space constraints require a 0805 package size while maintaining moderate noise suppression capabilities. The 200mA current rating suits low-power signal lines rather than high-current power rails. Consider the 500mOhm DC resistance impact on voltage drop if used in sensitive bias circuits. Evaluate the 2.2kOhm impedance at 100MHz against the specific noise frequencies present in your system.
