BBUP00201209331Y00

Overview

The BBUP00201209331Y00 is a shielded ferrite chip bead manufactured by Pulse Electronics. It features a 0805 (2012 metric) surface-mount package with dimensions of 2.00 mm length, 1.25 mm width, and 1.10 mm maximum height. The component provides an impedance of 330 Ohms at 100 MHz and supports a maximum DC current of 3 A. Its maximum DC resistance is 50 milliohms, and it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated shielding design minimizes electromagnetic interference coupling
• High current handling capability suitable for power line filtering
• Compact surface-mount footprint for dense PCB layouts

Applications

• Power supply output filtering
• DC-DC converter noise suppression
• Signal line EMI reduction in portable devices

Procurement Notes

Verify the specific manufacturer designation, as source data indicates potential attribution variance between Pulse Electronics and Chilisin Electronics for this part number. Confirm RoHS compliance status and exact dimensional tolerances against the official datasheet prior to integration. Ensure the supplier documentation explicitly references the 3A rating and 330 Ohm impedance specifications to avoid substitution errors.

Selection Notes

Select this component when high current capacity is required alongside significant impedance at 100 MHz. The shielded construction is advantageous for sensitive circuits where magnetic field containment is necessary. Compare the 50 milliohm DC resistance against circuit loss requirements. Evaluate the 0805 package size against available board space constraints relative to unshielded alternatives.

Part Context

This component belongs to the BBUP series of ferrite beads. It serves as a passive filter element designed to attenuate high-frequency noise on electrical lines. The product falls under the broader category of ferrite chips and is distinct from RF inductors or general-purpose chokes due to its specific impedance characteristics and shielding properties.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative shielded ferrite beads offering identical 330 Ohm impedance at 100 MHz and a minimum 3A current rating before substitution.
