BBBK00160808121Y00

Overview

The BBBK00160808121Y00 is a multilayer ferrite chip bead manufactured by Pulse Electronics, designed for surface-mount technology applications. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current rating of 400 mA and has a maximum DC resistance of 250 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer construction for compact surface-mount integration
• Shielded design to minimize electromagnetic interference
• High current handling capability relative to package size

Applications

• Noise suppression in high-speed digital signal lines
• Power supply filtering for integrated circuits
• EMI reduction in portable electronic devices

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 0603 package footprint matches the target PCB layout. Ensure the 400 mA current rating meets the circuit requirements under expected operating temperatures. Check for any recent product change notices regarding assembly origin or material composition.

Selection Notes

Select this component when a 120 Ohm impedance at 100 MHz is required for noise attenuation in space-constrained designs. The 0603 package allows for dense board layouts compared to larger ferrite beads. The 400 mA current rating makes it suitable for moderate power lines where lower DC resistance is critical to prevent voltage drop. Consider the -55°C to +125°C operating range for industrial or automotive environments.

Part Context

This part belongs to the BBGK/BBSJ/BBBK series of shielded ferrite beads from Pulse Electronics. These components are engineered for EMI suppression in consumer electronics and telecommunications equipment. The series offers various impedance values and current ratings within standardized packages like 0603 and 0402, providing designers with options for balancing noise performance and physical space constraints.

Replacement Considerations

Direct substitutes must match the 120 Ohm impedance, 400 mA current rating, and 0603 package dimensions. Verify compatibility with existing PCB footprints and soldering profiles. Alternative parts from other manufacturers should be evaluated for similar impedance-frequency characteristics and thermal stability.
