BK1608HS221-T

Overview

The BK1608HS221-T is a surface-mount ferrite bead manufactured by Taiyo Yuden, designed for high-current applications in electronic circuits. It features a compact 0603 (1608 metric) package size, suitable for space-constrained PCB layouts. The component provides an impedance of 220 ohms at 100 MHz, effectively suppressing electromagnetic interference and high-frequency noise. It supports a rated current of 2.0 A with a maximum DC resistance of 0.075 ohms, ensuring minimal signal loss while maintaining robust performance in power supply lines and data interfaces.

Feature Summary

• High current handling capability for stable operation in power delivery networks
• Compact 0603 footprint enabling dense circuit board integration
• Effective high-frequency noise suppression through specified impedance characteristics

Applications

• Power supply filtering in portable electronic devices
• Noise suppression on USB and high-speed data interface lines
• EMI reduction in mobile communication modules

Procurement Notes

Verify the complete part number including the suffix -T to ensure correct tape-and-reel packaging configuration. Confirm that the required current rating and impedance specifications align with the specific circuit design requirements before ordering. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when a balance between high current capacity and significant high-frequency attenuation is required in a small form factor. Ensure the DC resistance meets the voltage drop constraints of the target application. Consider the self-resonant frequency characteristics if the noise spectrum extends beyond standard measurement ranges.

Part Context

This ferrite bead belongs to Taiyo Yuden's BK series, which focuses on high-performance noise suppression components. The HS variant typically denotes high-current specifications within the lineup. These components are widely used in consumer electronics and industrial equipment where reliable EMI control is critical without compromising power efficiency.

Replacement Considerations

Cross-reference with other 0603 ferrite beads offering similar 220-ohm impedance and 2A current ratings from manufacturers like Murata or TDK. Verify physical dimensions and terminal configurations to ensure mechanical compatibility during substitution.
