BBBK00321611501Y00

Overview

The BBBK00321611501Y00 is a multilayer ferrite chip bead manufactured by Pulse Electronics. It features a shielded SMD/SMT construction in a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component provides an impedance of 500 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 150 mOhms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Shielded design for effective electromagnetic interference suppression
• Multilayer ferrite construction for compact surface-mount integration
• Wide operational temperature capability for harsh environments

Applications

• High-speed signal line filtering under 1 GHz
• Power supply noise suppression
• RF circuit interference mitigation

Procurement Notes

Verify the specific impedance value against official datasheets, as naming conventions may vary between 150 Ohms and 500 Ohms variants within the same series. Confirm RoHS compliance status and packaging details directly with the manufacturer or authorized distributors before ordering. Ensure the selected variant matches the required current rating and DC resistance specifications for the target application.

Selection Notes

Select this component when high impedance attenuation is required in a shielded 1206 footprint. Evaluate the 500 mA current handling capability against the circuit's peak load requirements. Consider the low DC resistance to minimize voltage drop and power loss in sensitive power lines. Verify thermal stability requirements align with the -55°C to +125°C operating range.

Part Context

This part belongs to the Pulse Electronics BBBK series of multilayer ferrite beads. The series offers various impedance values and current ratings in standard metric packages. These components are designed for general-purpose EMI suppression in portable electronics and industrial equipment where space constraints and shielding are critical factors.

Replacement Considerations

Check for direct substitutes within the BBBK series with matching impedance and current ratings. Compare physical dimensions and terminal configurations to ensure PCB compatibility. Verify equivalent performance characteristics such as DC resistance and temperature stability before substituting.
