BK20104L121-T

Overview

The BK20104L121-T is a multilayer chip bead array inductor manufactured by Taiyo Yuden. It features a 0804 (2010 Metric) package with an 8-pad configuration. The component provides four independent lines, each delivering an impedance of 120 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 100 mA and exhibits a maximum DC resistance of 700 milliohms.

Feature Summary

• Integrates four independent ferrite bead lines within a single compact surface-mount package
• Provides high impedance to suppress electromagnetic interference across multiple signal paths simultaneously
• Designed for efficient noise filtering in dense circuit layouts requiring multi-channel protection

Applications

• Noise suppression in portable electronic devices
• Signal line filtering in communication equipment
• EMI reduction in automotive electronics

Procurement Notes

Verify the specific suffix 'L' against official Taiyo Yuden documentation to confirm characteristic parameters. Ensure compatibility with reflow soldering processes as specified in the manufacturer's handling guidelines. Confirm RoHS3 compliance status through current datasheets before integration into production.

Selection Notes

Select this component when multi-line noise suppression is required in space-constrained designs. The 0804 footprint offers a balance between performance and board area efficiency. Verify that the 100 mA current rating meets the operational requirements of the target circuits to prevent saturation or excessive heating during normal operation.

Part Context

This part belongs to the BK array series of multilayer ceramic chip bead inductors from Taiyo Yuden. These components are engineered for high-density applications where multiple signal lines require simultaneous filtering.
