ACML-0402HC-050-T

Overview

The ACML-0402HC-050-T is a multilayer ferrite chip bead from the Abracon ACML-HC series, designed for high-current noise suppression applications. It features an impedance of 5 ohms at a test frequency of 100 MHz and supports a maximum DC current rating of 2 A. The component utilizes a surface-mount 0402 (1005 metric) package with dimensions of 1 mm in length, 0.5 mm in width, and 0.5 mm in height. It operates within a temperature range of -55°C to +125°C and exhibits a maximum DC resistance of 50 milliohms.

Feature Summary

• High current handling capability rated at 2 amperes for power line filtering
• Low impedance value of 5 ohms at 100 MHz for minimal signal attenuation
• Compact 0402 surface-mount footprint suitable for space-constrained designs

Applications

• Noise suppression in digital equipment such as computers and peripheral devices
• Filtering in communication equipment and mobile handsets
• Power line decoupling in portable electronic devices

Procurement Notes

Verify component availability status prior to procurement planning, as this specific part number may be classified as obsolete by the manufacturer. Confirm that the 0402 package dimensions and 2A current rating align with your circuit requirements. Ensure compatibility with standard SMD/SMT reflow soldering processes. Review the official datasheet for precise impedance characteristics and thermal performance data before finalizing design integration.

Selection Notes

Select this component when low impedance is required alongside high current capacity in a compact form factor. The 5-ohm impedance at 100 MHz makes it suitable for suppressing high-frequency noise without significantly affecting DC power delivery. Consider the 0402 package size for board space optimization. Verify that the 2A current rating exceeds the maximum operating current of the target circuit to prevent saturation or overheating issues during normal operation.

Part Context

This component belongs to the Abracon ACML-HC series of multilayer ferrite chip beads, which are engineered for high-current applications. The series offers various impedance values tailored for different noise suppression needs while maintaining small footprints. These beads are commonly used in consumer electronics and industrial equipment where effective EMI/RFI filtering is critical for signal integrity and regulatory compliance.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific obsolete model are not available in the provided documentation. Designers should consult the manufacturer's official obsolescence notices or contact Abracon directly for recommended alternatives. When selecting a replacement, ensure the new component matches the 0402 package dimensions, 2A current rating, and 5-ohm impedance specifications to maintain circuit performance.
