BBSJ00100505221Y00

Overview

The BBSJ00100505221Y00 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 220 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 operating temperature range spans from -55°C to +125°C.

Feature Summary

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

Applications

• High-frequency noise suppression in portable electronics
• Signal line filtering in communication modules
• Power rail decoupling in compact circuit boards

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with Pulse Electronics or authorized distributors before procurement. Confirm that the shielded variant matches the design requirements for EMI reduction. Ensure the 0402 footprint aligns with the PCB layout. Check for any factory special order constraints or minimum packaging quantities that may affect supply chain planning.

Selection Notes

Select this component when a shielded ferrite bead is required in a 0402 footprint to prevent crosstalk. The 220 Ohm impedance at 100 MHz suits high-frequency noise attenuation. The 400 mA current rating must exceed the signal line's DC bias. Verify that the 400 mOhm DCR does not introduce excessive voltage drop. The wide temperature range ensures reliability in harsh environments.

Part Context

This part belongs to the BBSJ series of shielded ferrite beads from Pulse Electronics. It is distinct from the BBSY series, which typically uses larger packages like 0603. The BBSJ series is designed for applications requiring compact size and magnetic shielding. It serves as a specialized solution for EMI control in space-constrained designs compared to unshielded alternatives.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching impedance, current rating, and shielding characteristics with other manufacturers' 0402 shielded ferrite beads.
