HCB10-390-RC

Chip Ferrite Bead Overview

The HCB10-390-RC is a single-line ferrite bead from Allied Components International, housed in an 0805 (2012 Metric) surface-mount package. It exhibits an impedance of 39 Ohms at 100 MHz and a maximum DC resistance of 20 milliohms. The component supports a current rating of 3 Amperes and operates within a temperature range of -55°C to +125°C. With a tolerance of ±25%, it serves as a power line filter designed for high-frequency noise suppression in compact electronic circuits.

Chip Ferrite Bead Feature Summary

• Provides effective high-frequency noise attenuation for power lines
• Supports high continuous current handling capabilities
• Operates reliably across extended industrial temperature ranges

Chip Ferrite Bead Applications

• Power line filtering in portable electronics
• Noise suppression in automotive control modules
• EMI reduction in industrial communication interfaces

Chip Ferrite Bead Procurement Notes

Verify the specific datasheet version for the HCB10-390-RC to confirm exact impedance curves and thermal derating characteristics. Ensure that the 0805 footprint matches the target PCB layout constraints. Confirm RoHS compliance status if required by the final assembly specifications. Cross-reference the 3A current rating with actual circuit load conditions to prevent saturation or excessive heating during operation.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile solution is required for suppressing broadband noise on single-ended power traces. The 0805 package offers a balance between current capacity and board space efficiency. Consider the 20 milliohm DC resistance impact on voltage drop for sensitive loads. Evaluate the 39 Ohm impedance value against the specific frequency spectrum of the interference to be mitigated.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the HCB series of passive components manufactured by Allied Components International. These beads are engineered for surface-mount technology applications requiring reliable EMI/RFI suppression. The product line focuses on providing robust filtering solutions for modern electronic devices where space is limited and performance stability is critical under varying environmental conditions.

Chip Ferrite Bead Replacement Considerations

The HCB10-390-RC shares similarities with the HCB10-400-RC model from the same manufacturer. Both units utilize the 0805 package and share identical electrical ratings regarding DC resistance and current handling. Verify impedance specifications carefully, as variations exist between different suffix codes within the series.
