MFBA3V1608K-121-R

Overview

The MFBA3V1608K-121-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features an impedance of 120 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 0.6 A. The component has a maximum DC resistance of 250 mOhms and operates within a temperature range of -55°C to +150°C. It utilizes a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height.

Feature Summary

• Multilayer chip construction for compact high-frequency noise suppression
• High thermal stability rated for operation up to +150°C
• Shielded design to minimize electromagnetic interference

Applications

• High-frequency EMI suppression in automotive electronics
• Signal line filtering in consumer devices
• Power supply noise attenuation in industrial equipment

Procurement Notes

Verify the specific suffix K against official Eaton documentation to confirm packaging or tolerance variations. Confirm RoHS compliance status directly from the manufacturer datasheet before integration. Ensure the selected variant matches the required 0.6A current rating and 120 Ohm impedance specifications for the target circuit application.

Selection Notes

Select this component when high-temperature performance exceeding standard limits is required. The 0603 footprint allows for dense PCB layouts while maintaining adequate current handling. Verify that the 250 mOhm DC resistance meets the voltage drop requirements of the specific power rail being filtered.

Part Context

This part belongs to the MFBA3V series of shielded ferrite beads designed for robust electronic environments. The series offers various impedance values within the same 0603 form factor, allowing designers to customize noise suppression characteristics without altering the physical board layout constraints.

Replacement Considerations

Cross-reference with other Eaton MFBA3V series variants for different impedance levels. Verify mechanical compatibility with existing footprints when substituting.
