ACML-0603-221-T

Overview

The ACML-0603-221-T is a surface-mount ferrite bead from the Abracon ACML series, designed for electromagnetic interference (EMI) suppression in compact electronic circuits. Housed in a standard 0603 (1608 metric) package with dimensions of 1.6 mm length and 0.8 mm width, this component provides an impedance of 220 ohms at 100 MHz. It supports a maximum DC current rating of 500 mA while maintaining a maximum DC resistance of 450 milliohms. The device operates reliably within a temperature range of -55°C to +125°C and features a 25% impedance tolerance.

Feature Summary

• Provides high-frequency noise attenuation through controlled impedance characteristics
• Supports compact board layouts via standard 0603 surface-mount packaging
• Capable of handling moderate DC currents without saturation

Applications

• General-purpose EMI filtering in consumer electronics
• Signal line protection in communication equipment
• Power supply noise suppression in portable devices

Procurement Notes

Verify the specific impedance value and current rating against the official Abracon datasheet prior to integration. Confirm that the 0603 package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Selection Notes

Select this component when space constraints require a 0603 form factor but higher current handling than smaller packages allows. The 220-ohm impedance at 100 MHz targets common noise frequencies in digital circuits. Consider the 450-milliohm DC resistance impact on power integrity if used in low-voltage lines. Evaluate thermal performance under continuous load conditions within the specified temperature limits.

Part Context

This ferrite bead belongs to the Abracon ACML series, which offers various impedance values and package sizes for EMI suppression. The ACML-0603-221-T specifically addresses applications requiring balanced size and current capacity. Similar parts in the series include different impedance ratings such as 31 ohms or 80 ohms, allowing designers to tune filtering characteristics based on specific frequency requirements.

Replacement Considerations

Direct substitutes must match the 0603 package, 220-ohm impedance at 100 MHz, and 500 mA current rating. Verify equivalent DC resistance and temperature ranges before substitution. Consult manufacturer cross-reference lists for approved alternatives.
