Overview
The ACML-0402H-221-T is a high-current multilayer ferrite chip bead from the Abracon ACML-H series. It provides an impedance of 220 ohms at 100 MHz with a maximum DC current rating of 400 mA and a maximum DC resistance of 300 milliohms. The component utilizes a 0402 (1005 metric) surface-mount package measuring 1.0 mm in length, 0.5 mm in width, and 0.65 mm in height. It operates within a temperature range of -55°C to +125°C and features a 25% impedance tolerance.
Feature Summary
- High current handling capability suitable for power line filtering applications
- Multilayer ferrite construction for compact surface-mount integration
- Low DC resistance design to minimize signal loss and power dissipation
Applications
- Power line noise suppression in portable electronic devices
- EMI filtering for high-speed digital circuits
- Signal integrity protection in communication modules
Procurement Notes
Verify the specific suffix and manufacturer part number against official Abracon documentation to ensure correct impedance and current ratings. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Check for updated datasheets as specifications may vary by production batch or revision.
Selection Notes
Select this component when high current capacity is required in a small 0402 footprint. Compare the 400 mA rating against circuit load requirements to prevent saturation. Ensure the 220 ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Verify thermal performance within the specified operating temperature range.
Part Context
This part belongs to the ACML-H series, which distinguishes itself through enhanced current handling compared to standard ACML variants. The 'H' designation indicates high-current optimization while maintaining the compact 0402 form factor common in modern miniaturized electronics.
Replacement Considerations
Cross-reference with other 0402 ferrite beads offering similar 220 ohm impedance and >400 mA current ratings. Verify pin compatibility and physical dimensions before substitution.
