BK20104S431-T

Chip Ferrite Bead Overview

The BK20104S431-T is a multilayer chip bead array inductor from the Taiyo Yuden BK series. It features four independent ferrite bead channels housed in an 0804 (2010 metric) surface-mount package with eight pads. The component provides an impedance of 430 ohms at 100 MHz and supports a maximum current rating of 100 mA. Its DC resistance is specified as 550 milliohms per channel, designed for high-frequency noise suppression in compact electronic circuits.

Chip Ferrite Bead Feature Summary

• Four-channel array configuration for simultaneous multi-line filtering
• Compact 0804 footprint suitable for space-constrained designs
• High impedance characteristics effective for high-frequency noise attenuation

Chip Ferrite Bead Applications

• Noise suppression on high-speed digital signal lines
• EMI reduction in portable communication devices
• Filtering power or data lines in compact consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the specific datasheet revision and impedance tolerance before integration. Confirm that the 100 mA current rating aligns with your circuit's operational requirements. Ensure the 0804 package dimensions match your PCB land pattern. Check RoHS compliance status if required by your manufacturing standards.

Chip Ferrite Bead Selection Notes

Select this component when multiple signal lines require individual noise filtering within a limited board area. The four-channel design reduces component count compared to discrete beads. Ensure the 430-ohm impedance matches the target frequency range for effective attenuation. Verify that the 550-milliohm DC resistance does not cause excessive voltage drop in low-voltage applications.

Chip Ferrite Bead Part Context

This part belongs to the Taiyo Yuden BK Array series of multilayer chip bead inductors. These components are engineered for high-density mounting and efficient electromagnetic interference suppression. The series offers various impedance values and channel counts to accommodate diverse filtering needs in modern electronic assemblies.

Chip Ferrite Bead Replacement Considerations

Consult official Taiyo Yuden documentation for verified substitute part numbers. Do not assume functional equivalence based solely on package size or nominal impedance. Cross-referencing requires matching channel count, current rating, and impedance specifications.
