BBBK00321611301Y00

Overview

The BBBK00321611301Y00 is a shielded multilayer ferrite bead from Pulse Electronics, designed for surface-mount applications. It operates within a temperature range of -55°C to +125°C and features a 1206 (3216 metric) package. The component provides an impedance of 300 ohms at 100 MHz with a tolerance of 25%. It supports a maximum DC current of 400 mA and maintains a maximum DC resistance of 200 milliohms.

Feature Summary

• Shielded multilayer construction minimizes electromagnetic interference coupling
• High-temperature stability ensures reliable operation across extended thermal ranges
• Low DC resistance reduces power loss in signal lines

Applications

• RF signal line filtering
• Digital circuit noise suppression
• Power supply decoupling

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 1206 package dimensions align with the PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly.

Selection Notes

Select this component when a 300-ohm impedance is required for high-frequency noise attenuation. The 400 mA current rating suits moderate signal currents. The shielded design is preferred for dense layouts where crosstalk reduction is critical. Verify compatibility with standard reflow soldering profiles.

Part Context

This part belongs to the Pulse Electronics BBBK series of ferrite beads. The series offers various impedance values and current ratings in standardized SMD packages. These components are engineered for general-purpose EMI suppression in consumer and industrial electronics.

Replacement Considerations

The BBBK00321611301Y00 is functionally equivalent to the MG3261-301Y. Both parts share similar electrical characteristics and package dimensions. Substitution requires verification of impedance tolerance and thermal performance limits.
