FB20010-3B-RC

Chip Ferrite Bead Overview

The FB20010-3B-RC is a wide-band ferrite bead from Bourns Inc., designed for high-frequency noise suppression. It features an impedance of 780 Ohms at 100 MHz with a tolerance of 25%. The component utilizes an axial leaded package, measuring 10.01 mm in length and 5.99 mm in outer diameter, with a 0.61 mm inner diameter. It supports a maximum current rating of 5A and contains 2.5 coil turns.

Chip Ferrite Bead Feature Summary

• Wide-band choke design for effective noise attenuation across broad frequency ranges
• Axial leaded construction facilitating through-hole mounting applications
• High current handling capability suitable for power line filtering

Chip Ferrite Bead Applications

• Electromagnetic interference (EMI) filtering on DC power lines
• Noise suppression in high-speed digital signal circuits
• Common mode noise reduction in communication interfaces

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value against the latest manufacturer datasheet, as sources cite both 780 Ohms and 785 Ohms. Confirm the axial lead configuration matches your PCB layout requirements. Ensure the 5A current rating aligns with your circuit's operational load to prevent saturation or thermal issues during procurement validation.

Chip Ferrite Bead Selection Notes

Select this component when wide-band attenuation is required rather than narrow-band resonance. The axial form factor dictates board space orientation. Verify that the 5A current limit exceeds peak circuit currents. Consider the physical dimensions (10mm length) for clearance constraints compared to surface-mount alternatives.
