BK0603TM800-T

Overview

The BK0603TM800-T is a multilayer chip bead inductor from the Taiyo Yuden BK series, designed for surface-mount applications. It features an impedance of 80 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 500 mA and has a maximum DC resistance of 180 mOhms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 0.6 mm in length, 0.3 mm in width, and 0.33 mm in height, corresponding to the 0201 (0603 metric) package.

Feature Summary

• Multilayer construction for compact high-frequency noise suppression
• Unshielded design suitable for general signal line filtering
• Surface-mount termination for automated assembly integration

Applications

• High-speed data line noise suppression
• Power supply output filtering
• General-purpose EMI suppression in consumer electronics

Procurement Notes

Verify the specific suffix 'TM' against official Taiyo Yuden documentation to confirm packaging and material specifications, as datasheets may vary by distributor listing. Confirm RoHS compliance status directly with the manufacturer or authorized supplier before procurement. Ensure the source document explicitly lists this exact part number to avoid confusion with similar variants like BK0603TS800-T.

Selection Notes

Select this component when a low-impedance path is required alongside moderate noise attenuation at 100 MHz. The 500 mA current rating suits low-power digital circuits. Verify that the 0201 footprint matches the PCB layout constraints. Compare the 180 mOhms DCR against circuit power loss requirements to ensure compatibility with the target voltage rail.

Part Context

This part belongs to the BK series of multilayer ferrite beads, which are engineered for suppressing electromagnetic interference in compact electronic devices. The BK series utilizes proprietary ceramic materials to provide stable impedance characteristics across a wide frequency range while maintaining small form factors suitable for modern miniaturized hardware designs.
