ACMS321611A310

Overview

The ACMS321611A310 is a single-line power line ferrite bead from the Max Echo ACMS series, designed for EMI suppression in surface-mount applications. It features a 1206 (3216 Metric) package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.10mm. The component provides an impedance of 31 Ohms at 100 MHz and supports a rated current of 3A. Its DC resistance is specified at a maximum of 30mOhm. It operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Provides effective electromagnetic interference suppression for power lines through high-impedance characteristics at target frequencies.
• Engineered for surface-mount integration into compact electronic assemblies using standard 1206 footprint dimensions.
• Capable of handling continuous currents up to 3A while maintaining low DC resistance to minimize power loss.

Applications

• Power supply input filtering on printed circuit boards
• EMI suppression for data lines in consumer electronics
• Noise reduction in portable device power circuits

Procurement Notes

Verify the specific suffix codes against official Max Echo documentation to ensure correct impedance and current ratings. Confirm RoHS3 compliance status if required by regulatory standards. Check moisture sensitivity level and storage conditions prior to assembly. Ensure the supplier provides valid traceability documents matching the manufacturer's part number format.

Selection Notes

Select this component when a 1206 footprint is required for power line filtering with a 3A current capacity. The 31 Ohm impedance at 100 MHz suits general noise suppression needs. Consider the 30mOhm DCR for efficiency requirements. Compare against similar series parts like BCMS if higher current ratings are needed, as that variant supports 6A.

Part Context

This part belongs to the ACMS3216 series of multilayer ferrite chip beads manufactured by Max Echo. These components are designed to suppress electromagnetic interference in high-speed signal and power lines. The series offers various impedance values and current ratings within the same 1206 package form factor to accommodate different circuit design requirements.

Replacement Considerations

The BCMS321611A310 is a verified substitute offering identical impedance but with a higher 6A current rating and lower DC resistance. Verify pin compatibility and thermal performance before substitution.
