BK0402HS700-T

Overview

The BK0402HS700-T is a multilayer chip bead inductor from the Taiyo Yuden BK series, designed for signal line filtering. It features a 01005 (0402 metric) surface-mount package with one circuit line. The component exhibits an impedance of 70 Ohms at 100 MHz. It utilizes an internal silver printed layer to create a closed circuit that functions as a magnetic shield, minimizing heat generation and crosstalk. The device is RoHS3 compliant and lead-free.

Feature Summary

• Internal silver printed layer creates a closed circuit acting as a magnetic shield
• Minimizes heat generation and crosstalk through magnetic shielding design
• Signal line filtering application with single-line configuration

Applications

• Signal line noise suppression
• High-frequency circuit filtering
• Electromagnetic interference reduction in compact electronics

Procurement Notes

Verify the specific ordering suffix matches the required impedance and package dimensions. Confirm RoHS3 compliance status if environmental regulations apply. Ensure the supplier provides official datasheets for electrical characteristics. Check termination style compatibility with assembly processes. Validate manufacturer authenticity through authorized channels.

Selection Notes

Select this component for applications requiring compact signal filtering in space-constrained designs. The 01005 package size suits high-density PCB layouts. Consider the 70 Ohm impedance profile for target frequency attenuation. Evaluate thermal management needs due to the magnetic shield's heat dissipation properties. Ensure the single-line configuration meets circuit topology requirements.

Part Context

This ferrite bead belongs to the BK series of multilayer chip bead inductors by Taiyo Yuden. The series targets general-purpose signal line filtering in consumer and industrial electronics. The BK0402HS700-T variant specifically addresses high-frequency noise suppression in miniature form factors. It represents a standard solution for EMI mitigation in modern electronic assemblies.

Replacement Considerations

Cross-reference with other 01005 ferrite beads offering 70 Ohm impedance at 100 MHz. Verify equivalent magnetic shielding capabilities and current ratings. Ensure mechanical footprint compatibility for direct replacement. Confirm impedance tolerance specifications match system requirements.
