BK2125HS220-T

Chip Ferrite Bead Overview

The BK2125HS220-T is a multilayer chip bead inductor from the Taiyo Yuden BK series, designed for high-current noise suppression applications. It features a single-line configuration housed in an 0805 (2012 metric) surface-mount package with dimensions of 2.00mm x 1.25mm x 1.05mm maximum height. The component provides an impedance of 22 Ohms at 100 MHz and supports a rated current of 1.2A. Its DC resistance is specified at a maximum of 50 milliohms. Operating reliably within a temperature range of -55°C to 125°C, this ferrite bead is RoHS3 compliant and classified under ECCN EAR99.

Chip Ferrite Bead Procurement Notes

This component is officially discontinued by the manufacturer as per Product Change Notification dated February 25, 2021. Availability is restricted to remaining stock only; no new production units are manufactured. Buyers must verify existing inventory levels carefully before ordering, as replenishment is not guaranteed. Final selection requires confirmation of datasheet specifications due to potential lifecycle changes.

Chip Ferrite Bead Selection Notes

Engineers should evaluate alternative components from the same BK series or newer generations due to the discontinuation status. Verify that substitute parts meet the required 1.2A current rating and 22 Ohm impedance at 100 MHz. Ensure the replacement package matches the 0805 mechanical constraints and thermal characteristics for seamless integration into existing designs.

Chip Ferrite Bead Part Context

Part of the Multilayer Chip Bead Inductors (BK Series), this component utilizes advanced ceramic technology to provide effective electromagnetic interference suppression. The BK series is engineered for stability in demanding environments, offering consistent performance across wide temperature ranges while maintaining low profile dimensions for modern compact electronics.
