EBMS100505K300

Overview

The EBMS100505K300 is a multilayer ferrite chip bead manufactured by Max Echo, designed for signal line noise suppression. It features a 0402 (1005 Metric) surface-mount package with dimensions of 1.00mm length and 0.50mm width. The component provides an impedance of 30 Ohms at 100 MHz and supports a maximum rated current of 300mA. Its maximum DC resistance is specified at 150 milliohms. The device operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Multilayer construction for effective high-frequency noise attenuation in compact designs
• Single-line configuration optimized for signal integrity protection
• Surface-mount compatibility with standard 0402 footprint dimensions

Applications

• High-speed digital signal line filtering
• Power supply noise suppression in portable electronics
• EMI reduction in communication interface circuits

Procurement Notes

Verify the specific suffix 'K' against official Max Echo documentation to confirm the precise DC resistance value of 150 milliohms, as suffixes often denote tolerance or material variations. Ensure the selected packaging format aligns with automated assembly requirements. Cross-reference the manufacturer part number directly with the datasheet to validate electrical parameters before integration into the bill of materials.

Selection Notes

Select this component when a low-impedance path is required alongside moderate noise suppression at 100 MHz. The 300mA current rating suits applications where minimal voltage drop is critical. Compare the 150 milliohm DCR against alternatives if power loss constraints are tight. Verify that the 0402 package fits the available PCB real estate and that the operating temperature range meets environmental specifications.

Part Context

This part belongs to the EBMS series of multilayer ferrite beads from Max Echo Technology Corp., which specializes in passive components for noise suppression. The series utilizes advanced ceramic materials to achieve stable impedance characteristics across wide frequency bands. These components are engineered for use in consumer electronics, telecommunications, and industrial equipment requiring reliable EMI control in space-constrained environments.

Replacement Considerations

EBMS100505A300 is listed as a parameter-equivalent substitute by the distributor, though it specifies a higher DC resistance of 200 milliohms compared to the K300's 150 milliohms. BMC1EY0030AN from TE Connectivity is also identified as a potential alternative. Verify impedance curves and current ratings for any cross-manufacturer substitution.
