ACMS160808A221 2A

Overview

The ACMS160808A221 2A is a multilayer ferrite chip bead designed for power line EMI suppression. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.60mm x 0.80mm and a maximum height of 0.95mm. The component provides an impedance of 220 Ohms at 100 MHz and supports a rated current of 2A. Its DC resistance (DCR) is maximized at 80 milliohms. It operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Multilayer construction for high-current power line applications
• Compact 0603 surface-mount footprint for space-constrained designs
• Low DC resistance to minimize power loss in supply lines

Applications

• Power supply input filtering
• EMI suppression on digital logic lines
• Noise reduction in portable electronic devices

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct impedance and current ratings. Confirm that the ordering information matches the required packaging format, such as tape and reel quantities. Cross-reference the part number with the latest revision history to avoid obsolete stock. Ensure compliance with project-specific environmental regulations like RoHS3 before finalizing procurement orders.

Selection Notes

Select this component when a low-profile solution is required for high-current power rails. The 2A rating suits applications where standard beads may saturate. The 0603 size allows for dense PCB layouts. Verify that the 220 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Ensure the operating temperature range meets the environmental conditions of the end-use device.

Part Context

This part belongs to the ACMS series of multilayer ferrite chips from Max Echo. These components are engineered specifically for suppressing electromagnetic interference in power lines. The series offers various impedance values and current ratings within standardized package sizes to facilitate design flexibility across different electronic product categories.

Replacement Considerations

Check for direct substitutes within the same ACMS series or equivalent offerings from other manufacturers that match the 0603 footprint, 2A current rating, and 220 Ohm impedance specifications. Ensure any replacement maintains the same DCR and temperature characteristics.
