• High current handling capability suitable for power line filtering
• Compact 0402 surface-mount footprint for space-constrained designs
• Multilayer ferrite construction for effective high-frequency noise suppression

Applications

• Power supply output filtering
• DC-DC converter noise attenuation
• High-speed digital signal line protection

Procurement Notes

Verify the specific impedance value and current rating against the official Abracon datasheet prior to procurement, as manufacturing revisions may occur. Confirm that the 0402 package dimensions align with your PCB land pattern requirements. Ensure the operating temperature range meets your environmental specifications. Check for RoHS compliance documentation if required by your regulatory framework. Validate availability through authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when high current capacity is required in a minimal 0402 footprint. Compare the 580 milliohm DC resistance against circuit loss tolerances. Evaluate the 1000 ohm impedance at 100 MHz against target noise frequencies. Consider the -55°C to +125°C range for industrial or automotive environments. Verify compatibility with standard SMT reflow profiles.

Part Context

This part belongs to the ACML-H series of multilayer ferrite beads, characterized by enhanced current handling compared to standard variants. It utilizes ceramic ferrite materials to provide broadband noise suppression. The series is engineered for reliability in demanding electronic applications requiring compact EMI filtering solutions.

Replacement Considerations

Consult the official Abracon cross-reference guide for verified substitutes. Ensure any replacement matches the 0402 package size, 1000 ohm impedance at 100 MHz, and minimum 300 mA current rating. Verify identical DC resistance and temperature specifications to maintain circuit performance.
