BK2125LM252-TV

Chip Ferrite Bead Overview

The BK2125LM252-TV is a multilayer ferrite chip bead inductor from the Taiyo Yuden BK series, housed in an 0805 (2012 metric) surface-mount package. It provides an impedance of 2.5 kOhms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 200 mA and has a maximum DC resistance of 750 mOhms. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive reliability standards.

Chip Ferrite Bead Feature Summary

• Internal silver printed layer creates a closed circuit acting as a magnetic shield to minimize heat generation and crosstalk.

Chip Ferrite Bead Applications

• Automotive electronic circuits requiring AEC-Q200 compliance
• High-frequency noise suppression in compact PCB layouts
• Signal integrity protection in portable devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix TV for reel packaging requirements against your manufacturing equipment specifications. Confirm that the AEC-Q200 rating aligns with your target application's automotive or industrial reliability standards. Check for end-of-life notifications or alternative sourcing options due to potential supply chain constraints associated with this discontinued or limited-stock item.

Chip Ferrite Bead Selection Notes

Select this component when high impedance at 100 MHz is required in a standard 0805 footprint. The low DC resistance ensures minimal voltage drop for 200 mA loads. Consider the internal shielding feature if thermal management or electromagnetic interference reduction is critical. Ensure the operating temperature range covers your environmental conditions.

Chip Ferrite Bead Part Context

This part belongs to the BK series of multilayer chip bead inductors by Taiyo Yuden. The series utilizes proprietary multilayer technology to achieve high performance in small packages. The LM designation typically indicates specific material characteristics optimized for high-impedance applications compared to other series variants like HS or HM.
