BBGK00201209121Y00

Overview

The BBGK00201209121Y00 is a shielded multilayer ferrite chip bead manufactured by Pulse Electronics. It features an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 800 mA and has a maximum DC resistance (DCR) of 150 mOhms. Designed for surface mount technology, it utilizes the 0805 (2012 metric) package with physical dimensions of 2 mm length, 1.25 mm width, and 0.9 mm height. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated shielding structure to minimize electromagnetic interference coupling
• Multilayer ceramic construction for compact surface-mount integration
• High-temperature stability suitable for demanding operational environments

Applications

• Signal line filtering in high-frequency circuits
• Noise suppression on data transmission lines
• EMI reduction in portable electronic devices

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 0805 footprint matches the target PCB layout. Ensure the operating temperature range aligns with the final assembly environment requirements.

Selection Notes

Select this component when a shielded ferrite bead is required for 0805 space-constrained designs. The 120 Ohm impedance at 100 MHz targets specific noise frequencies. The 800 mA current rating must exceed the signal line's peak DC bias to prevent saturation.

Part Context

This part belongs to the BBGK series of shielded ferrite beads from Pulse Electronics. The series offers various impedance and current combinations within standard SMD packages. The BBGK designation indicates a shielded multilayer chip bead designed for EMI suppression.

Replacement Considerations

Cross-reference with other BBGK series parts for different impedance values. Verify compatibility with alternative shielded ferrite beads from other manufacturers if supply constraints exist.
