Overview
The ACMS321611A700 is a multilayer ferrite chip bead manufactured by Max Echo, designed for EMI suppression in power lines. It features a 1206 (3216 Metric) surface-mount package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.10mm. The component provides an impedance of 70 Ohms at 100 MHz and supports a maximum current rating of 3A. Its DC resistance (DCR) is maximized at 40mOhm. It operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.
Feature Summary
- Multilayer construction for effective electromagnetic interference suppression
- Designed specifically for power line filtering applications
- Surface-mount technology compatible with automated assembly processes
Applications
- Power supply input filtering
- DC-DC converter output noise reduction
- General-purpose EMI suppression on power traces
Procurement Notes
Verify the manufacturer part number ACMS321611A700 against official Max Echo documentation to ensure authenticity. Confirm that the received components match the specified 1206 package size and electrical characteristics. Check for compliance with RoHS3 regulations as stated in the datasheet. Ensure storage conditions maintain moisture sensitivity level 1 integrity prior to soldering.
Selection Notes
Select this component when a low DC resistance of 40mOhm is required to minimize voltage drop in high-current circuits up to 3A. The 70 Ohm impedance at 100 MHz offers specific attenuation characteristics suitable for common switching frequencies. The 1206 footprint allows for standard PCB layout practices while providing adequate thermal handling for power line applications.
Part Context
This part belongs to the ACMS series of multilayer ferrite chips from Max Echo Technology Corp. The series focuses on EMI suppression using ceramic ferrite materials integrated into a compact surface-mount format. The ACMS321611A700 represents a specific impedance variant within the 3216 metric size family, targeting power rail protection.
Replacement Considerations
Consult Max Echo official documentation for direct cross-references. Verify that any substitute maintains the 3A current rating and 40mOhm DCR to prevent thermal issues. Ensure the replacement offers comparable impedance at 100 MHz for equivalent noise suppression performance.
