BBBK00201209121Y00

Overview

The BBBK00201209121Y00 is a multilayer ferrite chip bead manufactured by Pulse Electronics, designed for surface-mount applications. It features an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component has a maximum DC resistance of 250 mOhms and supports a maximum DC current of 300 mA. It operates within a temperature range of -55°C to +125°C. The physical dimensions correspond to the 0805 (2012 metric) package, measuring 2 mm in length, 1.25 mm in width, and 0.9 mm in height.

Feature Summary

• Shielded construction for effective electromagnetic interference suppression
• Multilayer ferrite technology for compact SMD integration
• AEC-Q200 qualification for automotive reliability standards

Applications

• Automotive electronic circuit protection
• High-frequency noise filtering in signal lines
• Power supply decoupling in compact devices

Procurement Notes

Verify the specific ordering suffix against official datasheets to ensure correct impedance and current ratings. Confirm RoHS compliance status and AEC-Q200 qualification requirements prior to procurement. Check for alternative packaging options such as cut tape or reel availability based on production volume needs.

Selection Notes

Select this component when a shielded ferrite bead with 120 Ohm impedance at 100 MHz is required for 0805 footprints. Ensure the circuit current does not exceed 300 mA to prevent saturation. Consider the low DCR of 250 mOhms for minimal voltage drop in sensitive power paths.

Part Context

This part belongs to the ABBK/BBBK series of shielded ferrite beads from Pulse Electronics. These components are engineered for high-density PCB layouts where EMI suppression is critical. The series offers various impedance values tailored for different frequency ranges while maintaining consistent mechanical dimensions.

Replacement Considerations

Cross-reference with GZ2012E601TF for potential functional equivalence. Verify pinout compatibility and thermal characteristics before substitution.
