The ACML-0402HC-221-T is a multilayer ferrite chip bead from the Abracon ACML-HC series, designed for surface-mount applications in the 0402 (1005 metric) package. It exhibits an impedance of 220 ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 900 mA and maintains a maximum DC resistance of 0.16 ohms. It operates within a temperature range of -55°C to +125°C.
Verify the specific suffix 'HC' against official Abracon documentation to confirm high-current characteristics. Ensure the 0402 package dimensions align with PCB land patterns. Confirm RoHS compliance status through the manufacturer's datasheet rather than distributor summaries.
Select this component when high current capacity is required alongside significant impedance at 100 MHz. The low DC resistance minimizes voltage drop in power paths. Verify thermal performance under continuous load conditions within the specified operating temperature range.
This part belongs to the ACML-HC series, distinguished by enhanced current ratings compared to standard ACML variants. It serves as a passive EMI suppression component, utilizing ferrite material properties to dissipate high-frequency energy as heat while passing DC signals with minimal loss.
The impedance of 220 ohms is measured at a test frequency of 100 MHz.
No, the ACML-0402HC-221-T is an unshielded ferrite bead.
