BBNQ00160808121Y00

Overview

The BBNQ00160808121Y00 is a multilayer ferrite chip bead manufactured by Pulse Electronics, designed for surface-mount technology in the 0603 (1608 metric) package. It provides an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 400 mA and features a maximum DC resistance of 300 mOhms. It operates within a temperature range of -55°C to +125°C and includes shielding.

Feature Summary

• Multilayer construction for compact high-frequency noise suppression
• Shielded design to minimize electromagnetic interference
• Surface-mount compatibility for automated assembly

Applications

• High-speed signal line filtering under 1 GHz
• Power supply noise attenuation in portable devices
• EMI suppression in consumer electronics

Procurement Notes

Verify the specific part number against official Pulse Electronics documentation to confirm electrical parameters and packaging details. Ensure compatibility with existing PCB footprints and thermal management requirements. Cross-reference manufacturer datasheets for updated RoHS compliance status and moisture sensitivity levels before finalizing procurement decisions.

Selection Notes

Select this component when a 0603 footprint is required for filtering applications operating below 1 GHz. The 400 mA current rating suits low-power signal lines, while the 120 Ohm impedance targets specific noise frequencies. Verify that the 300 mOhm DC resistance meets system power loss constraints and that the shielded type aligns with EMI mitigation strategies.

Part Context

This component belongs to the BBNQ series of multilayer ferrite chip beads from Pulse Electronics. It shares the 0603 form factor with other series members but differs in impedance and current ratings. The series is engineered for general-purpose EMI suppression in space-constrained electronic designs requiring reliable surface-mount integration.
