BKP1005HS121-T

Chip Ferrite Bead Overview

The BKP1005HS121-T is a single-line ferrite chip bead from the BK series, manufactured by Taiyo Yuden. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm x 0.50mm and a maximum height of 0.55mm. The component provides an impedance of 120 ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1 A and has a maximum DC resistance of 140 mΩ. The operating temperature range spans from -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• High current handling capability suitable for power line filtering applications
• Low DC resistance design minimizes voltage drop in signal paths
• Compact 0402 footprint enables dense PCB layout integration

Chip Ferrite Bead Applications

• Power supply noise suppression in portable electronics
• EMI filtering on high-current data lines
• Signal integrity enhancement in compact consumer devices

Chip Ferrite Bead Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific packaging variations such as MouseReel or standard tape-and-reel formats. Ensure the part number suffix matches required specifications, as variants may exist. Validate lead times and availability status prior to order placement due to potential supply constraints.

Chip Ferrite Bead Selection Notes

Select this component when a 0402 ferrite bead with 1A current rating and 120 ohm impedance at 100 MHz is required. Consider the low DCR specification for efficiency-critical designs. Evaluate thermal performance within the -55°C to 125°C range against environmental requirements. Compare against similar BK series parts if space or current constraints differ.

Chip Ferrite Bead Part Context

This component belongs to Taiyo Yuden's BK series of multilayer ferrite beads, designed for EMI suppression in compact electronic circuits. The HS designation typically indicates high-current and low-DCR characteristics within the series. These components are widely used in mobile phones, tablets, and other space-constrained digital devices requiring effective noise filtering without significant signal attenuation.

Chip Ferrite Bead Replacement Considerations

Publicly confirmed substitute part numbers for BKP1005HS121-T were not identified in available documentation. Verify compatibility with alternative 0402 ferrite beads offering similar impedance and current ratings before substitution.
