BK0603LL220-T

Overview

The BK0603LL220-T is a multilayer ferrite chip bead manufactured by Taiyo Yuden, designed for surface-mount technology in the 0201 (0603 metric) package. It exhibits an impedance of 22 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 65 mOhms. It operates within a temperature range of -55°C to +125°C. Physical dimensions are 0.6 mm in length, 0.3 mm in width, and 0.33 mm in height.

Feature Summary

• Multilayer construction for compact high-frequency noise suppression
• Surface-mount design compatible with automated assembly processes
• Unshielded configuration suitable for general EMI filtering applications

Applications

• High-speed data line noise suppression
• Power supply input filtering
• General electromagnetic interference reduction in portable electronics

Procurement Notes

Verify the specific lifecycle status as sources indicate potential end-of-life or discontinuation notifications. Confirm RoHS compliance details directly from the manufacturer datasheet before integration. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel, to align with production requirements.

Selection Notes

Select this component when a low-impedance path is required for frequencies around 100 MHz. The 0201 footprint allows for dense PCB layouts. Verify that the 500 mA current rating meets the circuit's operational demands without exceeding thermal limits defined by the 65 mOhm DC resistance.

Part Context

This part belongs to the BK series of ferrite beads from Taiyo Yuden. It utilizes multilayer ceramic technology to provide effective attenuation of high-frequency noise. The 0201 package size represents a standard industry form factor for space-constrained consumer and industrial electronic devices requiring passive filtering.
