BK32164S121-T

Chip Ferrite Bead Overview

The BK32164S121-T is a multilayer ferrite chip bead array manufactured by Taiyo Yuden. It features four independent lines housed in a 1206 (3216 metric) surface-mount package with dimensions of 3.20mm x 1.60mm x 0.90mm. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 200 mA and has a maximum DC resistance of 180 milliohms. The device operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Four independent signal lines integrated into a single compact surface-mount package for efficient board space utilization.
• Multilayer construction designed for effective high-frequency noise suppression in digital circuits.
• RoHS 3 compliant material composition ensuring environmental safety standards.

Chip Ferrite Bead Applications

• Noise suppression for high-speed digital data lines
• EMC filtering in portable electronic devices
• Signal integrity protection in communication interfaces

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'S' against the target design, as it denotes the 200mA current rating variant distinct from other series members like 'M' or 'W'. Confirm availability status as multiple distributors list this part as discontinued or obsolete. Ensure the selected substitute matches the 1206 footprint and 120 Ohm impedance specifications to maintain circuit performance without redesign.

Chip Ferrite Bead Selection Notes

Select this component when four-channel noise filtering is required in a constrained 1206 area. The 200mA current rating suits moderate-power digital signals. Compare DCR values against power loss constraints. Verify that the 120 Ohm impedance at 100 MHz aligns with the target noise spectrum. Consider the -55°C to +125°C operating range for industrial or automotive environments if applicable.

Chip Ferrite Bead Part Context

This part belongs to the BK Array series of multilayer ferrite bead inductors. These components are engineered to suppress electromagnetic interference in compact electronics. The BK series utilizes proprietary ceramic materials to achieve high impedance characteristics while maintaining low DC resistance. This specific model represents a quad-line configuration optimized for multi-signal bus applications.

Chip Ferrite Bead Replacement Considerations

The Murata BLA31AG121SN4D is identified as a direct replacement alternative. Verify that the substitute maintains the 1206 footprint, 120 Ohm impedance, and compatible current handling capabilities before integration.
