ACMS321611A101

Overview

The Max Echo ACMS321611A101 is a single-line power line ferrite bead designed for 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 100 Ohms at 100 MHz and supports a maximum current rating of 3A. Its DC resistance is specified at a maximum of 40 milliohms. The device operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Multilayer chip construction for effective EMI suppression in compact form factors
• High current handling capability suitable for power line filtering applications
• Low DC resistance to minimize signal loss and power dissipation
• Surface mount design compatible with automated assembly processes

Applications

• Power supply input filtering
• DC-DC converter output noise reduction
• General purpose EMI suppression on high-current traces

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet, as suffixes may indicate variations. Confirm package dimensions and mounting type match the PCB footprint requirements. Ensure compliance with environmental regulations such as RoHS3 if required by the target market. Check manufacturer specifications for moisture sensitivity level and reflow soldering profiles to prevent component damage during assembly.

Selection Notes

Select this component when a low-profile ferrite bead is needed for high-current power lines. The 1206 package offers a balance between current capacity and board space. Consider the 100 Ohm impedance at 100 MHz for typical switching noise frequencies. Evaluate the 3A current rating to ensure it exceeds the maximum operating current of the circuit to avoid saturation or excessive heating.

Part Context

This part belongs to the ACMS series of multilayer ferrite chip suppressors manufactured by Max Echo Technology Corp. The series is designed for general-purpose EMI suppression in electronic circuits. The ACMS321611A101 specifically utilizes a 1206 metric case size, which is widely used in consumer electronics and industrial equipment for its standardized footprint and reliable performance in noise filtering applications.

Replacement Considerations

Cross-reference with other 1206 ferrite beads offering similar 100 Ohm impedance at 100 MHz and 3A current ratings. Verify that substitute components maintain the same DC resistance and physical dimensions to ensure compatibility with existing PCB layouts and assembly processes.
