HCB20-101-RC

Chip Ferrite Bead Overview

The HCB20-101-RC is a power line ferrite bead manufactured by Allied Components International in a 1206 (3216 Metric) surface-mount package. It provides an impedance of 100 Ohms at 100 MHz with a rated current capacity of 2.5A and a maximum DC resistance of 30mOhm. The component is RoHS compliant, lead-free, and classified under Moisture Sensitivity Level 1 for unlimited floor life.

Chip Ferrite Bead Feature Summary

• High current handling capability suitable for power line filtering applications
• Compact 1206 surface-mount footprint for space-constrained designs
• RoHS compliant and lead-free construction

Chip Ferrite Bead Applications

• Power line noise suppression
• EMI filtering in electronic circuits
• Signal integrity enhancement in high-speed digital systems

Chip Ferrite Bead Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official datasheet before integration. Confirm that the 1206 package dimensions align with the PCB layout requirements. Ensure compliance with RoHS directives if operating in regulated markets. Check for any specific storage or handling instructions related to its moisture sensitivity level classification.

Chip Ferrite Bead Selection Notes

Select this component when a 100 Ohm impedance at 100 MHz is required for power lines. The 2.5A rating must exceed the circuit's maximum operating current to prevent saturation. The 30mOhm DC resistance should be evaluated for acceptable voltage drop. The 1206 size offers a balance between performance and board space efficiency.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the HCB series from Allied Components International, designed for suppressing electromagnetic interference in compact electronic devices. The '101' suffix indicates the 100 Ohm impedance characteristic at the standard test frequency. It serves as a passive component to attenuate high-frequency noise without significantly affecting the DC signal path.

Chip Ferrite Bead Replacement Considerations

Direct substitutes must match the 1206 package, 100 Ohm @ 100 MHz impedance, and 2.5A current rating. Verify equivalent DC resistance and impedance curves. Cross-reference with other manufacturers offering similar power line ferrite beads in the same form factor.
