BBSY00100505301Y00

Overview

The BBSY00100505301Y00 is a multilayer ferrite chip bead manufactured by Pulse Electronics, designed for surface-mount applications. It features an impedance of 300 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 300 mA and exhibits a maximum DC resistance of 500 mOhms. Encased in a compact 0402 (1005 metric) package measuring 1 mm x 0.5 mm x 0.5 mm, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer ferrite construction for effective electromagnetic interference suppression
• Shielded design to contain magnetic fields and reduce crosstalk
• Compact 0402 footprint suitable for high-density PCB layouts

Applications

• Electromagnetic interference filtering in portable electronics
• Signal line protection in mobile communication devices
• Power supply noise suppression in consumer hardware

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Pulse Electronics prior to procurement. Confirm that the 0402 package dimensions align with your PCB fabrication capabilities. Ensure that the 300 mA current rating meets the operational requirements of your target circuit to prevent performance degradation or thermal issues during use.

Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for EMI suppression in space-constrained designs. The 0402 package offers a balance between size and electrical performance. Consider the 300 mA current limit and 500 mOhms DC resistance to ensure compatibility with low-power signal lines or power rails where minimal voltage drop is critical.

Part Context

This part belongs to the BBSY series of shielded multilayer ferrite beads from Pulse Electronics. The series provides various impedance options in standard SMD packages. The BBSY00100505301Y00 specifically targets applications requiring moderate impedance values in small form factors, distinguishing it from higher-current BBUP series or different impedance variants within the same family.

Replacement Considerations

Cross-reference alternative suppliers for equivalent 0402 ferrite beads with 300 Ohms impedance and similar current ratings. Verify that any substitute maintains the same shielding characteristics and temperature range to ensure consistent EMI performance without redesigning the layout.
