BBBK00201209222Y00

Overview

The BBBK00201209222Y00 is a shielded multilayer ferrite chip bead from the Pulse Electronics BBBK series, designed for general signal lines under 1 GHz. It features an 0805 (2012 metric) surface-mount package with dimensions of 2 mm length, 1.2 mm width, and 0.9 mm height. The component provides an impedance of 2.2 kOhms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 200 mA and has a maximum DC resistance of 0.7 Ohms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Multilayer ferrite technology for high-frequency noise suppression
• Suitable for general signal line protection under 1 GHz

Applications

• General signal line filtering in electronic circuits
• Noise suppression for high-speed digital signals
• EMI reduction in compact surface-mount designs

Procurement Notes

Verify the specific impedance value against official datasheets, as conflicting sources list 60 Ohms or 2.2 kOhms for similar part numbers. Confirm RoHS compliance status directly with the manufacturer. Ensure the selected packaging option matches production requirements, as availability may vary by region and distributor.

Selection Notes

Select this component when shielding is required to prevent magnetic field interaction in dense layouts. The 0805 footprint offers a balance between current handling and board space. Verify that the 200 mA current rating meets the circuit's operational demands without causing excessive thermal rise or saturation.

Part Context

This part belongs to the BBBK series of RF inductors and ferrite beads manufactured by Pulse Electronics. The series includes various impedance values and current ratings within standard SMD packages like 0402, 0603, and 0805. These components are engineered for EMI suppression in consumer electronics and industrial applications requiring reliable noise filtering.

Replacement Considerations

Cross-reference with other BBBK series parts for different impedance levels if noise profiles vary. Check for equivalent shielded ferrite beads from other manufacturers offering identical 0805 dimensions and 200 mA ratings to ensure mechanical compatibility.
