BBSY00100505181Y00

Overview

The BBSY00100505181Y00 is a shielded multilayer ferrite chip bead manufactured by Pulse Electronics. It features a 0402 (1005 metric) surface-mount package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 180 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 400 mA and has a maximum DC resistance of 400 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Shielded construction to minimize electromagnetic interference
• Multilayer ferrite chip design for compact integration
• Surface-mount termination for automated PCB assembly

Applications

• High-speed signal line filtering
• DC power supply noise suppression
• RF circuit EMI mitigation

Procurement Notes

Verify the specific manufacturer part number against official datasheets to ensure compatibility with design requirements. Confirm RoHS compliance status through authorized channels. Check for any recent obsolescence notices or alternate pinout configurations before finalizing procurement plans.

Selection Notes

Select this component when space constraints require a 0402 footprint. Ensure the circuit current does not exceed 400 mA to prevent saturation. Verify that the 180 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Consider the 400 mOhm DCR impact on voltage drop in low-voltage applications.

Part Context

This component belongs to the BBSY series of shielded ferrite beads from Pulse Electronics. The series is designed for high-density electronic assemblies requiring effective noise suppression in minimal board space. The BBSY designation indicates specific shielding characteristics distinct from unshielded counterparts.
