BBBK00321611221Y00

Overview

The BBBK00321611221Y00 is a shielded multilayer ferrite bead manufactured by Pulse Electronics, designed for surface-mount technology in the 1206 (3216 metric) package. It provides an impedance of 220 Ohms with a tolerance of 25% and supports a maximum DC current of 400 mA. The component features a maximum DC resistance of 200 mOhms and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Multilayer ferrite chip design for compact SMD integration
• High-temperature stability suitable for demanding environments

Applications

• Signal line noise suppression
• Power supply filtering
• RF circuit protection

Procurement Notes

Verify the specific datasheet version for the BBBK00321611221Y00 before procurement. Confirm RoHS compliance status and lead times directly with authorized distributors or Pulse Electronics. Ensure storage conditions align with manufacturer guidelines to maintain component integrity prior to assembly.

Selection Notes

Select this component when a 1206 footprint is required for signal line filtering. The 400 mA current rating and 220 Ohm impedance make it suitable for low-current digital lines. Verify that the shielded type meets EMI requirements compared to unshielded alternatives in the same series.

Part Context

This part belongs to the BBBK series of ferrite beads from Pulse Electronics. The series offers various impedance values and current ratings in standard SMD packages. The BBBK designation indicates a shielded multilayer ferrite bead optimized for high-frequency noise suppression in portable and industrial electronics.

Replacement Considerations

Check for direct substitutes with identical 1206 dimensions and 220 Ohm impedance. Verify current handling capabilities match the 400 mA requirement. Ensure shielding characteristics are comparable to prevent EMI leakage in sensitive designs.
