ACMS201209A470

Overview

The ACMS201209A470 is a multilayer ferrite chip bead from the Max Echo ACMS2012 series, designed for EMI suppression in power lines. It features an impedance of 47 Ohms at 100 MHz and supports a rated current of 3 Amperes. The component exhibits a low DC resistance of 30 milliohms. It is manufactured in a compact 0805 (2012 Metric) surface-mount package, suitable for high-density circuit board layouts.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• High current handling capability for power line applications
• Compact surface-mount footprint for space-constrained designs

Applications

• Power supply input filtering
• DC-DC converter output noise reduction
• General-purpose EMI suppression on data or power lines

Procurement Notes

Verify the manufacturer designation as Max Echo when sourcing this component. Confirm the specific impedance value of 47 Ohms at 100 MHz matches your design requirements. Ensure the 0805 package size fits your PCB layout constraints. Check that the 3A current rating meets the operational load of your circuit to prevent saturation or excessive heating during normal operation.

Selection Notes

Select this part when a 47 Ohm impedance at 100 MHz is required for noise attenuation. The 3A current rating makes it suitable for moderate power applications. The 0805 package offers a balance between performance and board space. Consider the 30 milliohm DC resistance impact on voltage drop if efficiency is critical. Verify thermal management needs based on the expected operating current and ambient conditions.
