ACMS201209A520

Overview

The ACMS201209A520 is a power line ferrite bead from the Max Echo ACMS series, designed for EMI suppression in compact electronic circuits. Housed in an 0805 (2012 Metric) surface-mount package, it provides an impedance of 52 Ohms at 100 MHz. The component supports a maximum current rating of 3A and features a low DC resistance of 30mOhm. It operates reliably within a temperature range of -55°C to 125°C.

Feature Summary

• Multilayer ferrite chip construction for effective electromagnetic interference suppression
• Designed specifically for power line applications with high current handling capability
• Compact 0805 surface-mount footprint suitable for space-constrained designs

Applications

• Power supply input filtering
• DC-DC converter output noise reduction
• High-speed digital signal line protection

Procurement Notes

Verify the manufacturer part number ACMS201209A520 against official Max Echo documentation to ensure authenticity. Confirm that the specified impedance of 52 Ohms at 100 MHz and the 3A current rating match your circuit requirements. Check for any specific ordering suffixes or packaging variations such as tape and reel or cut tape if required by your assembly process.

Selection Notes

Select this component when a 0805 footprint is required for power line filtering with a target impedance near 52 Ohms at 100 MHz. Ensure the design can accommodate a 3A continuous current without exceeding the thermal limits defined by the 30mOhm DC resistance. Verify that the operating environment falls within the -55°C to 125°C range for reliable performance.

Part Context

This component belongs to the ACMS series of multilayer ferrite chip beads manufactured by Max Echo Technology Corp. The series is engineered for EMI suppression in various electronic applications. The ACMS201209A520 specifically utilizes the 2012 metric case size, balancing performance with board space efficiency for modern consumer and industrial electronics.

Replacement Considerations

Consult Max Echo official documentation for direct substitutes within the ACMS series. Cross-reference impedance curves and current ratings when considering alternative manufacturers. Ensure any replacement maintains the 0805 footprint and meets the 3A current requirement.
