MFBM1V1608-121-R

Overview

The Eaton MFBM1V1608-121-R is a multilayer chip ferrite bead designed for surface-mount applications. It operates within a temperature range of -40°C to +85°C and features a 0603 (1608 metric) package measuring 1.6 mm in length, 0.8 mm in width, and 0.8 mm in 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 of 2.0 A and has a maximum DC resistance of 65 mOhms. This single-channel device is shielded and complies with RoHS standards.

Feature Summary

• Multilayer construction enables effective electromagnetic interference suppression in compact designs
• Shielded architecture minimizes external magnetic field radiation
• High saturation current capability supports power line filtering applications

Applications

• Power line noise suppression
• Electromagnetic interference filtering
• Surface-mount circuit integration

Procurement Notes

Verify the specific part number against official Eaton Electronics documentation to confirm impedance and current ratings. Ensure compatibility with surface-mount assembly processes. Check for RoHS compliance status in the latest datasheet. Confirm packaging options such as reel or cut tape availability through authorized distributors. Validate that the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when a 0603 footprint is required for high-current EMI suppression. The 120 Ohm impedance at 100 MHz suits general-purpose noise attenuation. The 2.0 A current rating allows use in power delivery paths where lower impedance beads would saturate. Consider the 65 mOhms DC resistance for voltage drop calculations. Ensure the operating temperature range meets system requirements.

Part Context

This component belongs to the MFBM1V series of multilayer ferrite beads from Eaton Electronics. The series offers various impedance values within the same 0603 package form factor. These parts are engineered for automated surface-mount placement. The product line targets consumer electronics and industrial equipment requiring reliable noise control.

Replacement Considerations

Consult Eaton's official substitution guide for verified equivalents. Cross-reference impedance curves and current ratings carefully. Generic replacements may not match the specific multilayer construction or shielding characteristics.
