BBBK00201209202Y00

Overview

The BBBK00201209202Y00 is a shielded multilayer ferrite chip bead manufactured by Pulse Electronics. It features an impedance of 2 kOhms with a 25% tolerance and a maximum DC resistance of 700 mOhms. The component supports a maximum DC current of 200 mA and operates within a temperature range of -55°C to +125°C. Housed in a compact 0805 (2012 metric) surface-mount package measuring 2 mm x 1.2 mm x 0.9 mm, it provides effective high-frequency noise suppression for sensitive circuits.

Feature Summary

• Shielded multilayer construction minimizes electromagnetic interference coupling
• High impedance value suitable for suppressing broadband noise
• Compact 0805 footprint enables dense PCB layout integration

Applications

• High-speed digital signal line filtering
• Power supply noise attenuation
• RF circuit interference suppression

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official datasheet before implementation. Confirm that the 200 mA current rating meets the operational requirements of the target circuit. Ensure the 0805 package dimensions align with the designated PCB land pattern to guarantee proper soldering and mechanical stability.

Selection Notes

Select this component when high impedance at specific frequencies is required alongside low DC resistance. The 200 mA current handling capability suits moderate power applications. The shielded design is critical for environments requiring strict EMI control. Verify thermal performance within the specified -55°C to +125°C operating range for reliability.

Part Context

This part belongs to the BBBK series of shielded ferrite beads from Pulse Electronics. The series offers various impedance and current ratings in standard SMD packages. The BBBK designation indicates a multilayer ceramic structure designed for surface mount technology, providing consistent electrical characteristics across production batches.

Replacement Considerations

Consult manufacturer documentation for direct substitutes. Ensure replacement parts match the 2 kOhm impedance, 200 mA current rating, and 0805 package dimensions. Verify equivalent shielding effectiveness and temperature range compliance.
