ACMS201209A170

Overview

The Max Echo ACMS201209A170 is a multilayer ferrite chip EMI suppressor designed for power line noise suppression. It features an impedance of 17 Ohms at 100 MHz and supports a maximum current rating of 3A. The component has a maximum DC resistance of 30 milliohms and operates within a temperature range of -55°C to 125°C. It utilizes an 0805 (2012 Metric) surface mount package with dimensions of 2.0mm x 1.25mm.

Feature Summary

• Multilayer construction for effective high-frequency noise attenuation
• Designed specifically for single power line applications
• Capable of handling high continuous current loads

Applications

• Power supply input filtering
• DC-DC converter output noise suppression
• General-purpose EMI suppression in portable electronics

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official Max Echo datasheet prior to integration. Confirm that the 0805 footprint matches the PCB design requirements. Ensure the selected packaging format aligns with automated assembly capabilities. Cross-reference the RoHS compliance status with current regulatory standards for the target market.

Selection Notes

Select this component when a low-impedance path is required for power lines while maintaining significant attenuation at 100 MHz. The 3A current rating makes it suitable for higher power applications compared to standard signal-line beads. Consider the 0805 package size for space-constrained designs requiring robust thermal performance.
