BBSY00100505331Y00

Overview

The BBSY00100505331Y00 is a shielded multilayer ferrite chip bead manufactured by Pulse Electronics. It features a compact 1 mm x 0.5 mm x 0.5 mm surface-mount package designed for high-frequency signal filtering and EMI suppression. The component exhibits an impedance of 330 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 400 mA and maintains a maximum DC resistance of 100 mOhms. The device operates reliably within a temperature range of -55°C to +125°C.

Feature Summary

• Shielded multilayer construction minimizes electromagnetic interference coupling
• Compact 1005 footprint enables dense PCB layout integration
• High impedance value provides effective noise attenuation at target frequencies

Applications

• High-frequency signal filtering in mobile communication devices
• EMI suppression on data lines in consumer electronics
• Power line noise reduction in portable equipment

Procurement Notes

Verify the specific impedance tolerance and DC current ratings against the official datasheet before integration. Confirm that the 1005 package dimensions align with the target PCB land pattern. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when space constraints require a 1005 package size while needing significant impedance at 100 MHz. The shielded design is critical for applications sensitive to magnetic field leakage. Evaluate the 400 mA current rating to ensure it exceeds the peak operational current of the circuit to prevent saturation or excessive heating during normal use.

Part Context

This ferrite bead belongs to Pulse Electronics' BBSY series, which specializes in miniature shielding solutions. The series targets applications requiring robust EMI performance in limited board areas. The multilayer ceramic technology allows for precise impedance control and consistent manufacturing quality across production batches.
