ACMS321611A520

Overview

The ACMS321611A520 is a single-line power line ferrite bead manufactured by Max Echo, designed for surface mount assembly in the 1206 (3216 Metric) package. It provides an impedance of 52 Ohms at 100 MHz with a maximum DC resistance of 30mOhm and a rated current capacity of 3A. The component operates within a temperature range of -55°C to 125°C and measures 3.20mm x 1.60mm x 1.10mm.

Feature Summary

• Multilayer chip construction for EMI suppression on power lines
• High current handling capability suitable for power supply filtering
• Low DC resistance to minimize voltage drop and power loss

Applications

• Power line noise suppression in electronic circuits
• EMI filtering for high-current signal paths
• Component protection in automotive or industrial power systems

Procurement Notes

Verify the specific impedance value and current rating against the design requirements before ordering. Confirm the package dimensions match the PCB footprint. Check for RoHS compliance status if required by project specifications. Ensure the supplier provides official datasheets for technical validation.

Selection Notes

Select this component when a low-impedance path is needed for high-current applications requiring moderate high-frequency attenuation. Compare the 3A rating against peak load currents. Consider the 52 Ohm impedance at 100 MHz relative to the target noise frequency spectrum. Evaluate thermal performance under continuous load conditions.
