BK20104S241-T

Overview

The BK20104S241-T is a four-channel ferrite bead array manufactured by Taiyo Yuden in an 0804 (2010 metric) surface-mount package. It provides an impedance of 240 Ohms at 100 MHz with a maximum DC resistance of 450 mOhm and a current rating of 100 mA. Designed for signal line filtering, this component suppresses electromagnetic interference across multiple lines within a compact footprint.

Feature Summary

• Integrates four independent signal lines into a single compact package to facilitate high-density circuit board layouts.
• Provides wide frequency range impedance characteristics to effectively suppress noise and prevent mutual interference between circuits.

Applications

• Noise suppression in portable electronic devices
• Signal line filtering in liquid crystal display modules
• Electromagnetic interference reduction in laptop computers

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the 0804 package dimensions match your PCB footprint requirements. Ensure the 100 mA current rating meets your application's peak load needs. Check for RoHS compliance status if required by your manufacturing standards. Validate that the 240 Ohm impedance at 100 MHz aligns with your target noise frequencies.

Selection Notes

Select this component when multi-line filtering is required in space-constrained designs. The 0804 package offers a balance between performance and size. Consider the 450 mOhm DC resistance impact on signal integrity. Evaluate the 100 mA limit against your circuit's operational current. Compare impedance curves against other series options if broader frequency coverage is needed.

Part Context

This part belongs to Taiyo Yuden's BK series of multilayer chip beads. These components are engineered for high-frequency noise suppression in consumer electronics. The BK series emphasizes miniaturization while maintaining effective electromagnetic interference control for sensitive signal paths.

Replacement Considerations

Consult official Taiyo Yuden documentation for direct cross-references. Verify pinout compatibility and impedance profiles before substituting. Ensure replacement parts meet the same 0804 package constraints and electrical specifications.
