EBMS201209A102

Overview

The EBMS201209A102 is a single-line signal line ferrite bead manufactured by Max Echo in the EBMS series. It utilizes a multilayer chip construction housed in an 0805 (2012 Metric) surface-mount package with dimensions of 0.126" length and 0.063" width. The component provides an impedance of 1 kOhms at 100 MHz with a tolerance of ±25%. It supports a maximum current rating of 300mA and features a maximum DC resistance of 450mOhm. The device operates within a temperature range of -55°C to 125°C.

Feature Summary

• Multilayer ferrite chip construction for effective EMI suppression
• Single signal line configuration designed for high-frequency noise attenuation
• Surface-mount compatibility with standard 0805 footprint dimensions

Applications

• High-speed digital signal line filtering
• Power supply input/output noise suppression
• RF circuit interference mitigation

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's datasheet to confirm impedance tolerance and material composition, as suffixes often denote variations in electrical characteristics or packaging. Ensure the ordering part number matches the required 0805 package size and 300mA current rating. Confirm RoHS compliance status if restricted substances are a constraint for the final assembly process.

Selection Notes

Select this component when a compact 0805 footprint is required for signal integrity management. The 1 kOhm impedance at 100 MHz targets common switching noise frequencies. Verify that the 300mA current rating exceeds the peak operating current of the target circuit to prevent saturation. Consider the low DCR value to minimize voltage drop and power loss in sensitive signal paths.

Part Context

This component belongs to the Max Echo EBMS series of multilayer ferrite chip beads. The series is engineered for circuits operating between 0 and 3 amperes. The EBMS201209A102 specifically addresses the need for small-form-factor EMI suppression in modern electronic assemblies where space constraints limit the use of larger discrete components.
