Overview
The BK2125HM241-T is a multilayer chip bead inductor from the Taiyo Yuden BK series, housed in an 0805 (2012 metric) surface-mount package. It provides an impedance of 240 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 600 mA and has a maximum DC resistance of 200 mOhms. It operates within a temperature range of -55°C to +125°C and measures 2.00 mm x 1.25 mm x 1.05 mm.
Feature Summary
- Multilayer construction for compact high-frequency noise suppression
- High current handling capability suitable for power line filtering
- Low DC resistance to minimize signal loss
Applications
- Electromagnetic interference (EMI) suppression in electronic circuits
- Noise filtering on DC power supply lines
- Signal integrity protection in high-speed digital interfaces
Procurement Notes
This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors or verifying specific stock conditions. Engineers should confirm the current lifecycle status and lead times with authorized suppliers before finalizing designs, as production has ceased.
Selection Notes
Select this part when a 0805 footprint ferrite bead with 240 Ohms impedance at 100 MHz is required. Ensure the circuit current does not exceed 600 mA to prevent saturation. Verify that the operating temperature range of -55°C to +125°C meets environmental requirements. Consider alternative components if long-term supply stability is critical due to its obsolete status.
Part Context
The BK2125HM241-T belongs to the BK series of multilayer chip bead inductors manufactured by Taiyo Yuden. These components are designed for surface-mount technology and are commonly used in consumer electronics and industrial equipment for EMI/RFI noise suppression. The HM suffix typically denotes specific material characteristics optimized for high-current applications within the standard 0805 form factor.
Replacement Considerations
Publicly confirmed substitute part numbers were not identified in the provided source data. Users should consult official replacement guides or contact the manufacturer for qualified alternatives.
