BBFJ00100505601Y00

Overview

The BBFJ00100505601Y00 is a shielded multilayer ferrite bead manufactured by Pulse Electronics in an SMD/SMT 0402 (1005 metric) package. It provides an impedance of 600 Ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 300 mA and features a maximum DC resistance of 850 mOhms. It 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

• RF signal line filtering
• Power supply noise suppression
• High-speed data line protection

Procurement Notes

Verify the specific impedance value and DC resistance against the official datasheet before procurement, as distributor listings may contain conflicting specifications. Confirm the package dimensions match the target footprint. Ensure the operating temperature range meets the environmental requirements of the final application.

Selection Notes

Select this component when a low-profile 0402 ferrite bead is required for high-impedance noise attenuation. The 300 mA current rating suits moderate power lines. Verify that the 850 mOhm DCR does not cause excessive voltage drop in the circuit design compared to lower resistance alternatives.

Part Context

This part belongs to the BBSJ/BBSY/BBFJ series of shielded ferrite beads from Pulse Electronics. These components are designed for EMI suppression in portable electronics and communication devices where space is limited. The shielded variant reduces magnetic field leakage compared to unshielded types.

Replacement Considerations

Cross-reference with other 0402 shielded ferrite beads offering similar 600 Ohm impedance and 300 mA ratings. Verify pin compatibility and thermal characteristics before substitution.
