Overview
The BK1005LL241-T is a multilayer chip bead inductor from the Taiyo Yuden BK series, designed for high-frequency noise suppression. It features a single-line configuration housed in a compact 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 240 ohms at 100 MHz and supports a maximum DC current of 250 mA. Its maximum DC resistance is specified at 1.6 ohms, ensuring minimal signal loss in power lines. The device operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.
Feature Summary
- Multilayer construction for effective high-frequency electromagnetic interference suppression
- Single-line design suitable for power line filtering applications
- Compact 0402 footprint enabling dense PCB layout integration
Applications
- Noise suppression on power supply lines in portable electronic devices
- Filtering high-frequency interference in mobile communication equipment
- EMI reduction in automotive infotainment and control systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolescence status. Confirm RoHS3 compliance and moisture sensitivity level (MSL 1) requirements during storage and handling. Review latest datasheets for any potential parameter variations or end-of-life notices before finalizing procurement plans.
Selection Notes
Select this component when a 240-ohm impedance at 100 MHz is required for noise attenuation in space-constrained designs. Ensure the 250 mA current rating meets the specific circuit load requirements. Consider the 0402 package size compatibility with existing PCB footprints and reflow soldering profiles compatible with the specified operating temperature range.
Part Context
This ferrite bead belongs to the BK series of multilayer chip bead inductors manufactured by Taiyo Yuden. These components are engineered for EMI/RFI suppression in digital circuits. The BK series utilizes proprietary multilayer technology to achieve stable impedance characteristics across wide frequency bands, making them standard choices for modern consumer electronics and industrial applications requiring reliable noise control.
Replacement Considerations
Publicly confirmed substitute part numbers were not identified in the provided source material. Verify equivalent specifications such as impedance, current rating, and package dimensions when sourcing alternatives from other manufacturers.
