EBMS100505B301

Overview

The EBMS100505B301 is a multilayer ferrite chip bead from the Max Echo EBMS series, designed for EMI suppression in signal lines. 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 600 Ohms at 100 MHz and supports a maximum rated current of 50mA. Its DC resistance (DCR) is limited to a maximum of 1.5 Ohms. The device operates within a temperature range of -55°C to 125°C.

Feature Summary

• Multilayer ferrite construction for effective high-frequency noise attenuation
• Single-channel design optimized for signal line EMI suppression
• Compact 0402 footprint suitable for space-constrained surface-mount applications

Applications

• Signal line filtering in portable electronic devices
• EMI suppression in compact consumer electronics circuits
• Noise reduction in high-density PCB layouts requiring small form factors

Procurement Notes

Verify the specific impedance value of 600 Ohms at 100 MHz against your circuit requirements, as this differs from similar part numbers like the A300 variant which has 30 Ohms. Confirm the 50mA current rating is sufficient for your application, noting it is lower than some higher-current variants in the same series. Ensure the 1.5 Ohm DCR limit aligns with your power loss constraints. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when high impedance at 100 MHz is critical for signal integrity rather than power line filtering. The low current rating of 50mA makes it unsuitable for power rails but ideal for sensitive data lines. Compare against the EBMS100505A300 if lower impedance or higher current capacity is needed. Consider the physical size constraints of the 0402 package during layout planning.

Part Context

This part belongs to the EBMS series of multilayer ferrite chip beads manufactured by Max Echo Technology Corp. The series is engineered for circuits operating at currents ranging from 0 to 3 amperes across various package sizes. The EBMS100505B301 specifically utilizes the 1005 metric case size, distinguishing it from larger packages in the family while maintaining the core multilayer ferrite technology for EMI suppression.

Replacement Considerations

Publicly confirmed substitute part numbers include EBMS100505K300 from Max Echo, which offers parameter equivalence. Other potential alternatives may exist from different manufacturers, but direct cross-referencing should verify impedance and current ratings match the original specifications.
