BK1005HS241-T

Overview

The Taiyo Yuden BK1005HS241-T is a multilayer chip ferrite bead designed for high-current applications. It features an impedance of 240 Ohms at 100 MHz with a tolerance of 25%. The component supports a maximum rated current of 400 mA and maintains a low DC resistance of 300 milliohms maximum. Housed in a compact 0402 (1005 metric) surface-mount package measuring 1.00mm x 0.50mm, it operates within a temperature range of -55°C to 125°C.

Feature Summary

• High current handling capability suitable for power line filtering
• Low DC resistance minimizes voltage drop in signal paths
• Compact 0402 footprint enables dense circuit board layouts

Applications

• Noise suppression on high-current data lines
• EMI filtering in automotive electronic control units
• Signal integrity enhancement in portable devices

Procurement Notes

Verify the specific suffix designation carefully, as variants such as BK1005HS241-TV may exist with identical electrical characteristics but different packaging or tape specifications. Confirm that the sourced unit matches the required termination style and reel configuration for your assembly process. Cross-reference the manufacturer part number against official distributor databases to ensure authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a 0402 package while demanding significant current capacity. Ensure the target application frequency aligns with the 240 Ohm impedance peak at 100 MHz. Verify that the 400 mA rating exceeds the maximum continuous current of the protected circuit to prevent thermal failure. Consider the operating temperature range if the environment exceeds standard commercial limits.

Part Context

This component belongs to the BK series of multilayer chip beads from Taiyo Yuden. These components utilize specialized ceramic materials to provide effective electromagnetic interference suppression. The series is engineered for reliability in demanding environments, including automotive electronics certified to AEC-Q200 standards where applicable.

Replacement Considerations

The BK1005HS241-T is officially listed as obsolete. Public records indicate the TDK MMZ1005Y241CT000 as a similar substitute part number. Verify mechanical dimensions and electrical parameters against the original datasheet before substitution.
