BK1005LL220-T

Overview

The Taiyo Yuden BK1005LL220-T is a multilayer chip ferrite bead in the BK series, housed in a 0402 (1005 metric) surface-mount package. It provides an impedance of 22 Ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current rating of 400 mA and features a maximum DC resistance of 180 milliohms. It operates within a temperature range of -55°C to +125°C and complies with AEC-Q200 automotive standards.

Feature Summary

• Multilayer construction for compact EMI suppression
• Automotive grade reliability per AEC-Q200
• High current handling capability

Applications

• Electromagnetic interference suppression in automotive electronics
• Noise filtering on high-speed signal lines
• Power line noise reduction in compact devices

Procurement Notes

Verify the specific suffix against official Taiyo Yuden documentation, as variations may exist. Confirm end-of-life status and lead times directly with authorized distributors or the manufacturer before procurement planning. Ensure compatibility with RoHS3 regulations and moisture sensitivity level requirements for your assembly process.

Selection Notes

Select this component when a 0402 footprint is required for EMI filtering with a 22 Ohm impedance target. Evaluate the 400 mA current rating against peak circuit loads to prevent saturation. Consider the low DC resistance for minimal voltage drop in power integrity applications.

Part Context

This part belongs to the Taiyo Yuden BK series of multilayer chip beads. These components are designed for high-density PCB layouts where space is limited. The series offers various impedance values and current ratings to suit different filtering needs across consumer and automotive sectors.

Replacement Considerations

The TDK MMZ1005D220CTD25 is listed as a parameter-equivalent substitute. Verify pinout, impedance curves, and current ratings match your design requirements before substitution.
