MFBM1V2012-190-R

Overview

The Eaton MFBM1V2012-190-R is a multilayer chip ferrite bead designed for EMI suppression in surface-mount applications. It features an 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.25 mm width, and 1.2 mm height. The component provides an impedance of 19 Ohms at a test frequency of 100 MHz, with a tolerance range of 12 to 25 Ohms. It supports a maximum DC current of 6.0 A and has a maximum DC resistance of 10 mOhms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer construction for effective high-frequency noise attenuation
• Shielded design to minimize electromagnetic interference coupling
• High current handling capability suitable for power line filtering

Applications

• EMI suppression on high-current DC power lines
• Noise filtering in automotive electronic systems
• Signal integrity protection in industrial control circuits

Procurement Notes

Verify the specific impedance tolerance and DC current rating against the official Eaton datasheet before integration. Confirm that the 0805 footprint matches the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a compact 0805 form factor is required for high-current applications up to 6.0 A. The 19 Ohm impedance at 100 MHz targets specific noise frequencies. Compare the low DC resistance of 10 mOhms against voltage drop constraints. Evaluate the thermal performance under continuous load conditions relative to the ambient environment.

Part Context

This part belongs to the MFBM1V series of multilayer chip ferrite beads from Eaton Electronics Division. The series offers various impedance values and current ratings in standard SMD packages. These components are engineered for reliable EMI suppression in space-constrained electronics requiring robust current handling capabilities.

Replacement Considerations

Direct substitutes include other Eaton MFBM1V series parts with matching 0805 footprints and similar electrical characteristics. Verify impedance curves and saturation currents when considering alternatives from different manufacturers to ensure equivalent noise suppression performance.
