BK1005HW680-TV

Overview

The BK1005HW680-TV is a multilayer chip ferrite bead from the Taiyo Yuden BK series, designed for high-frequency noise suppression in compact electronic circuits. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.0 mm length and 0.5 mm height. The component provides an impedance of 68 Ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 170 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer construction for effective high-frequency electromagnetic interference filtering
• Compact 0402 footprint suitable for space-constrained printed circuit board layouts
• High current handling capability with low DC resistance to minimize signal loss

Applications

• Noise suppression in portable communication devices
• Filtering in automotive infotainment systems
• Signal integrity management in industrial control equipment

Procurement Notes

Verify part authenticity through authorized distributors as this component may be subject to obsolescence notices. Confirm that the specific suffix matches the required impedance and current ratings. Check for RoHS compliance documentation if environmental regulations apply to your assembly process. Ensure storage conditions maintain component integrity prior to soldering.

Selection Notes

Select this component when a 68 Ohm impedance at 100 MHz is required for single-line noise attenuation. The 0402 package size dictates board space availability. Ensure the operating environment stays within the specified -55°C to +125°C range. Verify that the 500 mA current rating exceeds the maximum expected DC load on the line to prevent saturation or excessive heating.

Part Context

This ferrite bead belongs to the BK series of multilayer chip beads manufactured by Taiyo Yuden. The series is engineered for general-purpose EMI suppression in consumer, automotive, and industrial electronics. The BK1005 designation indicates the 0402 case size, while HW specifies the material characteristics optimized for high-frequency performance.
