BBNQ00100505301Y00

Overview

The BBNQ00100505301Y00 is a shielded multilayer ferrite chip bead manufactured by Pulse Electronics. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 300 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 200 mA and has a maximum DC resistance (DCR) of 800 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated shielding design to minimize electromagnetic interference coupling
• Multilayer construction for compact surface-mount integration
• High impedance performance at 100 MHz for noise suppression

Applications

• Signal line filtering in portable electronic devices
• Noise suppression on high-speed data interfaces
• Power supply decoupling in compact circuit boards

Procurement Notes

Verify the specific electrical parameters against the official datasheet before procurement, as distributor listings may vary. Confirm the manufacturer part number matches exactly. Ensure the ordering suffix corresponds to the required packaging format. Check RoHS compliance status if mandated by project requirements. Validate the supplier's authorization status to guarantee component authenticity.

Selection Notes

Select this component when space constraints require a 0402 footprint with significant noise attenuation capabilities. The 200 mA current rating suits low-power signal lines rather than high-current power rails. Consider the 800 mOhm DCR impact on voltage drop if used in sensitive bias circuits. The shielded type is preferred over unshielded variants to prevent magnetic field interaction with nearby components.

Part Context

This part belongs to the BBNQ series of shielded ferrite beads from Pulse Electronics. The series utilizes multilayer technology to achieve high impedance in small packages. The 0402 size allows for high-density PCB layouts. The product falls under the broader category of passive ferrite components used for EMI suppression in modern electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative shielded ferrite beads from other manufacturers based on impedance curves, current ratings, and physical dimensions.
