ACMS160808A600

Overview

The ACMS160808A600 is a multilayer ferrite chip bead manufactured by Max Echo, designed for EMI suppression in power lines. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.60mm x 0.80mm and a maximum height of 0.95mm. The component provides an impedance of 60 Ohms at 100 MHz and supports a rated current of 3A. Its maximum DC resistance (DCR) is 40 milliohms. It operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Designed specifically for power line filtering applications
• Low DC resistance to minimize voltage drop in high-current circuits

Applications

• Power supply input filtering
• DC-DC converter output noise suppression
• General-purpose power line EMI mitigation

Procurement Notes

Verify the specific impedance value against design requirements, as the model suffix indicates 60 Ohms at 100 MHz, distinct from other variants like the A601 which offers higher impedance. Confirm the 3A current rating aligns with the application's peak load to prevent saturation. Ensure the 0603 footprint matches the PCB layout constraints. Check RoHS3 compliance documentation if required by regional regulations.

Selection Notes

Select this component when low impedance at 100 MHz is sufficient for noise reduction while maintaining high current handling capability. The 40 milliohm DCR makes it suitable for power rails where efficiency is critical. Compare with the EBMS series if signal line isolation is needed instead of power line filtering. Consider the physical height limit of 0.95mm for tight clearance designs.

Part Context

This part belongs to the ACMS1608 series of multilayer ferrite chip beads from Max Echo Technology Corp. The series is engineered for compact EMI suppression in electronic devices. The ACMS variant typically targets power lines, distinguishing it from the EBMS series which is often designated for signal lines. Both share similar form factors but differ in electrical characteristics and intended circuit placement.
