BBSY00100505121Y00

Overview

The BBSY00100505121Y00 is a shielded ferrite bead from Pulse Electronics, designed for surface mount technology (SMD/SMT) applications. It features a 0402 [1005 Metric] package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 120 ohms at a tolerance of ±25%. It supports a maximum DC current rating of 550 mA and has a maximum DC resistance (DCR) of 0.19 ohms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Compact 0402 surface mount footprint for space-constrained designs
• Rated for high-temperature operation up to +125°C

Applications

• General signal line filtering under 1GHz
• Noise suppression in compact electronic circuits
• High-density PCB layouts requiring small form factors

Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Pulse Electronics documentation to ensure compatibility with design requirements. Confirm that the shielded variant matches the intended noise suppression needs. Check RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure storage conditions align with moisture sensitivity levels if applicable.

Selection Notes

Select this component when a low-profile, shielded ferrite bead is required for signals below 1GHz. The 120-ohm impedance and 550 mA current rating suit moderate noise suppression tasks. The 0402 package allows integration into dense layouts. Consider the 0.19-ohm DCR impact on signal integrity and power loss. Verify thermal stability requirements against the -55°C to +125°C operating range.

Part Context

This part belongs to the BBSY series of ferrite beads from Pulse Electronics. It is categorized as a passive component used for EMI suppression. The series offers shielded options to reduce magnetic field leakage. It competes with other 0402 ferrite beads offering similar impedance and current ratings. The product is intended for consumer electronics and industrial applications requiring reliable noise filtering.

Replacement Considerations

Consult official substitution guides from Pulse Electronics for verified alternatives. Cross-reference impedance, current rating, and package dimensions when selecting substitutes. Ensure any replacement maintains the shielded characteristic if EMI reduction is critical. Verify thermal and electrical specifications match the original design constraints.
