BK1608LL680-T

Overview

The BK1608LL680-T is a multilayer chip bead inductor from the Taiyo Yuden BK series, designed for surface-mount technology. It features an impedance of 68 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 350 mOhms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1.6 mm in length, 0.8 mm in width, and 0.95 mm in height, conforming to the 0603 (1608 metric) package.

Feature Summary

• Multilayer construction for compact high-frequency noise suppression
• Surface-mount design compatible with standard SMD/SMT processes
• Stable impedance characteristics across specified operating temperatures

Applications

• High-speed signal line filtering
• Power supply noise suppression
• EMI/RFI mitigation in digital circuits

Procurement Notes

Verify end-of-life status as multiple sources indicate discontinuation. Confirm availability through authorized distributors or secondary markets if production continuity is required. Check RoHS compliance details and ensure the specific suffix matches design requirements before ordering.

Selection Notes

Select this component when a 68 Ohm impedance at 100 MHz is required for noise attenuation. Ensure the circuit current does not exceed 300 mA to prevent saturation. Verify that the 0603 footprint fits the PCB layout constraints and that the operating temperature range meets environmental specifications.
