BK1005HS121-TV

Overview

The Taiyo Yuden BK1005HS121-TV is a multilayer ferrite chip bead designed for high-current applications in the 0402 (1005 metric) surface-mount package. It provides an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 1 A and maintains a low maximum DC resistance of 140 mOhms. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification for automotive reliability.

Feature Summary

• AEC-Q200 qualified for automotive electronic systems
• High current handling capability up to 1 A
• Low DC resistance for minimal power loss
• Compact 0402 surface-mount footprint

Applications

• Automotive circuit noise suppression
• Industrial signal line filtering
• Power supply output decoupling

Procurement Notes

Verify part authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging options such as cut tape or reel configurations prior to ordering. Ensure the procurement source provides valid traceability documentation for automotive-grade components.

Selection Notes

Select this component when space constraints require a 0402 package but high current capacity is necessary. Compare against standard series parts if lower current ratings are acceptable. Verify that the 120 Ohm impedance profile matches the target noise frequency spectrum for effective EMI suppression.

Part Context

This part belongs to the BKP series, which distinguishes itself from the standard BK series by offering higher current ratings suitable for power lines. It shares the same physical dimensions as other 0402 ferrite beads but utilizes specialized materials to handle increased thermal loads without saturation.

Replacement Considerations
