BBBK00201209102Y00

Overview

The BBBK00201209102Y00 is a multilayer ferrite chip bead from the BBBK series, manufactured by Pulse Electronics. It features an 0805 (2012 metric) surface-mount package with dimensions of 2.0 mm length, 1.2 mm width, and 0.9 mm height. The component provides an impedance of 1000 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current rating of 200 mA and has a maximum DC resistance of 0.5 Ohms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer ferrite construction for effective high-frequency noise suppression
• Shielded design to minimize electromagnetic interference coupling
• Automotive-grade qualification compliant with AEC-Q200 standards

Applications

• General signal line filtering under 1 GHz
• Automotive electronic circuit protection
• High-density PCB layouts requiring compact shielding

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Pulse Electronics or authorized distributors before integration. Confirm that the 0805 footprint matches your PCB layout constraints. Ensure the 200 mA current rating meets your circuit's operational requirements to prevent saturation or excessive heating during normal use.

Selection Notes

Select this component when high impedance at 100 MHz is required in a compact shielded form factor. The AEC-Q200 qualification makes it suitable for automotive applications where reliability is critical. Compare the 0.5 Ohm DCR against other options if low voltage drop is a primary constraint, noting that higher impedance typically correlates with increased resistance.

Part Context

This part belongs to the BBBK series of multilayer ferrite beads designed for RF and digital signal lines. It shares the 0805 package family with variants like BBBK00201209600Y00 but differs significantly in impedance and current handling. The series emphasizes shielded performance to reduce crosstalk in dense electronic assemblies.

Replacement Considerations

ABPY00201209102Y00 offers identical 1 kOhm impedance and 0805 packaging but supports a higher current of 1.5 A. Verify if the increased current capacity aligns with your thermal management strategy.
