BBBK00321611272Y00

Overview

The BBBK00321611272Y00 is a shielded surface-mount ferrite bead from Pulse Electronics, housed in a 1206 (3216 metric) package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.30mm. It offers an impedance of 2.7 kOhms with a 25% tolerance and supports a maximum DC current of 300 mA. The component features a maximum DC resistance of 600 mOhms and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Multilayer ferrite core design for high-frequency noise suppression
• Surface-mount termination compatible with standard SMD/SMT assembly processes

Applications

• RF circuit noise filtering
• Signal line protection in electronic assemblies
• Power supply decoupling applications

Procurement Notes

Verify the specific impedance value of 2.7 kOhms and the 300 mA current rating against the official datasheet before integration. Confirm that the 1206 package dimensions and 600 mOhm DCR meet the board layout requirements. Ensure the operating temperature range of -55°C to +125°C aligns with the environmental conditions of the target application.

Selection Notes

Select this component when high impedance at RF frequencies is required alongside low DC resistance. The shielded design is suitable for dense PCB layouts where crosstalk reduction is critical. Consider the 300 mA current limit to ensure the component does not saturate or overheat during normal operation.

Part Context

This part belongs to the Pulse Electronics BBBK series of multilayer ferrite chip beads. These components are designed for RF inductor applications requiring compact footprints. The series provides various impedance values and current ratings within standardized metric packages like 1206.

Replacement Considerations

Check for direct substitutes within the BBBK series offering similar 2.7 kOhm impedance and 300 mA ratings. Verify pin compatibility and thermal characteristics if considering alternative manufacturers' ferrite beads in the 1206 package.
