Overview
The Taiyo Yuden BK1005LL220-TV is a single-line ferrite chip bead designed for surface mount applications. It features a 0402 (1005 metric) package with dimensions of 1.00mm x 0.50mm and a maximum height of 0.55mm. The component provides an impedance of 22 Ohms at 100 MHz with a tolerance of ±25%. It has a maximum DC resistance of 180 milliohms and a rated current of 400mA. The device operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- High-current capability in a compact 0402 footprint
- Low DC resistance for minimal power loss
Applications
- Automotive electronic circuit noise suppression
- High-frequency signal line filtering
- Power supply output decoupling
Procurement Notes
Verify the part status carefully as this specific model is listed as obsolete or end-of-life by major distributors. Confirm availability through authorized channels or check for valid alternative sources. Ensure that any substitute components meet the original electrical specifications and physical dimensions required for your design.
Selection Notes
Select this component when space constraints require a 0402 ferrite bead with specific high-current handling capabilities. The AEC-Q200 rating makes it suitable for automotive environments. Consider the 22 Ohm impedance at 100 MHz to ensure effective noise attenuation for the target frequency spectrum while maintaining low insertion loss due to its low DCR.
Part Context
This component belongs to the BK series of ferrite beads from Taiyo Yuden, specifically engineered for suppressing electromagnetic interference in compact electronic devices. The LL suffix typically denotes a multi-layer construction optimized for higher current ratings compared to standard variants in the same package size.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include TDK MMZ1005D220CTD25. Verify mechanical compatibility and electrical performance before substitution.
