HCB20-700-RC

Chip Ferrite Bead Overview

The HCB20-700-RC is a surface-mount ferrite bead manufactured by Allied Components International. It features a 1206 case size and provides an impedance of 70 Ohms at a test frequency of 100 MHz. The component has a maximum DC resistance of 20 milliohms and supports a maximum current rating of 4 Amperes. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high impedance for noise suppression in power lines
• Supports high continuous current up to 4 Amperes
• Operates reliably across extended industrial temperature ranges

Chip Ferrite Bead Applications

• Power supply output filtering
• Noise suppression on data buses
• EMI reduction in portable electronics

Chip Ferrite Bead Procurement Notes

Verify the specific impedance tolerance and current derating curves against the official datasheet before integration. Confirm that the 1206 package dimensions align with the target PCB footprint. Ensure the selected supplier provides traceable documentation for RoHS compliance and material composition as required by regulatory standards.

Chip Ferrite Bead Selection Notes

Select this component when a balance between low DC resistance and moderate impedance is required for high-current applications. The 1206 package offers a compact solution for space-constrained designs. Consider the 4A current rating to ensure thermal stability under peak load conditions without excessive self-heating.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the HCB20 series, designed for general-purpose EMI suppression. It complements other variants in the lineup such as the HCB20-300-RC and HCB20-800-RC, which offer different impedance levels while maintaining similar current handling capabilities and package styles for consistent design integration.

Chip Ferrite Bead Replacement Considerations

Compatible substitutes include the HCB20-300-RC and HCB20-800-RC from the same manufacturer. These alternatives share the 1206 package and similar electrical characteristics but differ in impedance values. Verify functional equivalence regarding current rating and temperature range before substitution.
