BBBK00321611700Y00

Overview

The BBBK00321611700Y00 is a shielded multilayer ferrite bead manufactured by Pulse Electronics, designed for surface-mount technology applications. It operates within a temperature range of -55°C to +125°C and features a maximum DC current rating of 500 mA with a 25% impedance tolerance. The component exhibits an impedance of 70 Ohms and a maximum DC resistance of 100 mOhms. Housed in a compact 1206 (3216 metric) package, this RF inductor provides effective noise suppression while maintaining low insertion loss for high-frequency signal integrity.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Multilayer ferrite core design for stable high-frequency performance
• Surface-mount compatibility for automated PCB assembly

Applications

• High-speed data line filtering
• Power supply noise suppression
• RF circuit impedance matching

Procurement Notes

Verify the specific impedance value against official datasheets, as distributor listings may vary between 70 Ohms and 150 Ohms for similar series codes. Confirm RoHS compliance status directly with the manufacturer before integration. Ensure the selected variant matches the required DC current handling capabilities for the target application circuit to prevent thermal issues during operation.

Selection Notes

Select this component when shielding is required to prevent magnetic field radiation from affecting nearby sensitive traces. The 1206 footprint offers a balance between current handling capacity and board space efficiency. Consider the 100 mOhm DCR limit for power integrity calculations and ensure the operating temperature range aligns with the environmental conditions of the final device enclosure.

Part Context

This part belongs to the BBBK series of shielded ferrite beads from Pulse Electronics. The series is engineered for demanding electronic environments requiring robust noise attenuation without compromising signal quality. The standardized 1206 package allows for easy replacement in existing designs that utilize similar form-factor components for EMI mitigation purposes.

Replacement Considerations

Cross-reference with BBBK00321611151Y00 if higher impedance is acceptable. Verify pinout and mechanical dimensions match the existing PCB land pattern before substitution.
