Overview
The ACML-0402HC-310-T is a multilayer ferrite chip bead from the Abracon ACML-HC series, designed for surface-mount applications. It provides an impedance of 31 ohms at a test frequency of 100 MHz with a maximum DC resistance of 60 milliohms. The component supports a maximum DC current rating of 1.5 A and operates within a temperature range of -55°C to +125°C. It utilizes a 0402 (1005 metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height.
Feature Summary
- High current handling capability suitable for power line filtering
- Compact 0402 surface-mount footprint for space-constrained designs
- Multilayer construction for reliable EMI suppression
Applications
- Power supply output filtering
- DC-DC converter noise suppression
- High-current signal line protection
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official Abracon datasheet prior to procurement. Confirm that the 0402 package dimensions align with the target PCB land pattern. Ensure the selected supplier provides traceable documentation matching the manufacturer's part number ACML-0402HC-310-T to guarantee component authenticity and performance consistency.
Selection Notes
Select this component when high current ratings are required in a minimal 0402 footprint. The 31-ohm impedance at 100 MHz targets specific noise frequencies while maintaining low DC resistance to minimize voltage drop. Compare the 1.5 A current rating against circuit requirements to ensure adequate margin for peak loads without saturation.
Part Context
This part belongs to the Abracon ACML-HC series, which specializes in high-current ferrite beads. The HC designation indicates enhanced current handling compared to standard variants. It complements the broader ACML family by offering solutions for power integrity management in compact electronic assemblies requiring effective electromagnetic interference reduction.
Replacement Considerations
Consult the official Abracon catalog for direct substitutes within the ACML-HC series. Verify equivalent impedance, current rating, and package dimensions before considering cross-brand alternatives. No public substitute part numbers are confirmed in the provided source material.
