BK1005HS241-TV

Overview

The Taiyo Yuden BK1005HS241-TV is a multilayer chip ferrite bead designed for high-current applications in the 0402 (1005 metric) surface-mount package. It provides an impedance of 240 Ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 400 mA and features a low maximum DC resistance of 300 mOhms. It operates within a temperature range of -55°C to 125°C and complies with AEC-Q200 automotive standards.

Feature Summary

• High current handling capability suitable for power line filtering
• Automotive-grade reliability certified under AEC-Q200 standards
• Compact 0402 footprint for dense PCB layouts
• Low DC resistance to minimize signal loss

Applications

• Automotive body and chassis circuits
• Infotainment system power filtering
• Industrial application noise suppression

Procurement Notes

Verify the specific suffix against official manufacturer documentation, as variations may exist. Confirm RoHS compliance and halogen-free status prior to integration. Ensure the source document explicitly lists this part number to avoid substitution errors. Check for any recent product change notices or obsolescence announcements directly from Taiyo Yuden.

Selection Notes

Select this component when space-constrained designs require effective EMI suppression on high-current lines. The 0402 size offers a balance between performance and board real estate. Consider the 400 mA rating to ensure adequate margin for peak load currents. Verify that the 240 Ohm impedance profile matches the target noise frequency spectrum.

Part Context

This part belongs to the BK series of multilayer chip beads from Taiyo Yuden, specifically engineered for automotive and industrial environments. The HS designation typically indicates high-surge or high-current characteristics within the family. These components are essential for maintaining signal integrity in noisy electronic systems.
