BK0603LL330-T

Overview

The Taiyo Yuden BK0603LL330-T is a multilayer ferrite chip bead inductor designed for surface mount technology. It features an impedance of 33 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 150 mA and has a maximum DC resistance of unspecified low value typical for this series. It operates within a temperature range of -55°C to +85°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
• Designed for surface mount assembly on printed circuit boards
• Provides signal integrity protection in sensitive electronic circuits

Applications

• General electronic equipment such as AV devices and office automation
• Information and communication equipment including mobile phones
• Personal computers and related peripheral hardware

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and specific lot traceability requirements before integration into production lines. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet to maintain solderability and electrical performance during assembly processes.

Selection Notes

Select this component when space constraints require a 0201 footprint for EMI filtering applications. Evaluate the 150 mA current rating against the operating load to prevent saturation. Consider the 33 Ohm impedance profile at 100 MHz to ensure effective attenuation of target noise frequencies without excessive signal loss in power lines.

Part Context

This part belongs to the BK series of ferrite beads from Taiyo Yuden, specifically engineered for high-density PCB layouts. The LL suffix typically denotes specific material characteristics optimized for general-purpose noise suppression in consumer electronics. It serves as a passive filter element to suppress electromagnetic interference in digital and analog signal paths.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult official Taiyo Yuden cross-reference guides or contact the manufacturer directly for validated alternatives that match impedance, current rating, and package dimensions.
