ACML-0805-221-T

Overview

The Abracon ACML-0805-221-T is a surface-mount ferrite chip bead from the ACML series, housed in an 0805 (2012 metric) package. It provides an impedance of 220 ohms at 100 MHz with a maximum DC resistance of 200 milliohms and a rated current of 600 mA. The component operates within a temperature range of -55°C to +125°C and features a tolerance of ±25%. Physical dimensions are 2 mm in length, 1.25 mm in width, and 0.85 mm in height.

Feature Summary

• Unshielded single-channel ferrite construction for electromagnetic interference suppression
• Surface-mount termination compatible with standard SMD/SMT assembly processes
• Wide operational temperature stability ranging from -55°C to +125°C

Applications

• OA equipment signal line filtering
• Video equipment noise suppression
• Audio equipment circuit protection
• Communication device EMI reduction

Procurement Notes

Verify the specific datasheet version for the ACML-0805-221-T to confirm impedance tolerances and thermal characteristics. Ensure that the selected supplier provides documentation confirming RoHS compliance. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit components. Confirm packaging formats such as cut tape or reel availability match production requirements before finalizing orders.

Selection Notes

Select this component when a 220 ohm impedance at 100 MHz is required for high-frequency noise attenuation. The 600 mA current rating suits moderate power applications where low DC resistance minimizes voltage drop. The 0805 footprint allows for compact PCB layouts. Consider the unshielded design for general-purpose EMI suppression where magnetic field containment is not critical.

Part Context

This ferrite bead belongs to the Abracon ACML family of chip beads designed for surface-mount technology. The series offers various impedance values and current ratings within standardized package sizes. The ACML-0805-221-T specifically targets applications requiring reliable EMI filtering in space-constrained environments while maintaining stable performance across wide industrial temperature ranges.

Replacement Considerations

Direct substitutes must match the 0805 package, 220 ohm impedance at 100 MHz, and 600 mA current rating. Verify equivalent DC resistance and temperature coefficients. Check for identical mounting footprints and terminal configurations to ensure mechanical compatibility without PCB redesign.
