EBMS160808A121

Overview

The EBMS160808A121 is a single-line ferrite bead from the Max Echo EBMS series, designed for signal line filtering in surface-mount applications. It features a 0603 (1608 metric) package with dimensions of 1.60mm x 0.80mm and a maximum height of 0.80mm. The component provides an impedance of 120 Ohms at 100 MHz and supports a maximum rated current of 400mA. Its DC resistance (DCR) is limited to a maximum of 150 milliohms. It operates within a temperature range of -55°C to 125°C and is RoHS3 compliant.

Feature Summary

• Multilayer chip construction for EMI suppression in compact designs
• Single-line configuration optimized for signal integrity
• Surface-mount compatibility with standard 0603 footprint

Applications

• Signal line noise filtering in electronic circuits
• EMI suppression in portable devices under 3A current loads
• High-frequency circuit protection requiring low DC resistance

Procurement Notes

Verify the manufacturer designation as Max Echo Technology Corp. when sourcing this component. Confirm the specific ordering suffix corresponds to the desired packaging format, such as tape and reel or cut tape, as these affect handling but not electrical function. Ensure the part status is active for production use. Cross-reference the DigiKey part number 5262-EBMS160808A121TR-ND for accurate inventory tracking and availability checks during procurement planning.

Selection Notes

Select this ferrite bead for applications requiring 120 Ohms impedance at 100 MHz with a 400mA current rating. The 0603 package size suits space-constrained PCB layouts. Consider the 150 milliohm DCR limit for power loss calculations. The wide operating temperature range supports diverse environmental conditions. Verify that the single-line topology matches the circuit's grounding and shielding requirements compared to multi-line alternatives.

Part Context

This component belongs to the EBMS series of multilayer ferrite chip beads manufactured by Max Echo Technology Corp. The series is engineered for EMI suppression in modern electronics. The EBMS160808A121 specifically utilizes a 0603 case size, balancing performance with board space efficiency. It complements the ACMS series, which addresses common mode noise, while this model focuses on differential or single-ended signal line filtering.

Replacement Considerations

Verified parameter-equivalent substitutes include Pulse Electronics BBGK00160808121Y00, Cal-Chip Electronics FB160808T-121Y-S, and TDK MMZ1608B121CTAH0. These parts share similar impedance and current ratings. Validate mechanical fit and thermal characteristics before substitution.
