BBBK00201209221Y00

Overview

The BBBK00201209221Y00 is a shielded multilayer ferrite chip bead manufactured by Pulse Electronics. It operates in the SMD/SMT 0805 (2012 metric) package with dimensions of 2 mm length, 1.2 mm width, and 0.9 mm height. The component provides an impedance of 220 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 300 mOhms. The device functions within a temperature range of -55°C to +125°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling.

Applications

• High-speed data line filtering
• Power supply noise suppression

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 0805 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a shielded ferrite bead is required for EMI suppression in compact designs. The 0805 form factor suits space-constrained layouts. Verify that the 300 mA current handling capability exceeds the circuit's peak load. Check that the 220 Ohm impedance matches the target noise frequency spectrum for effective attenuation.
