MFBM1V2012-300-R

Overview

The MFBM1V2012-300-R is a single-line ferrite bead from Eaton's MFBM1V series, designed for surface-mount applications in the 0805 (2012 metric) package. It provides an impedance of 30 Ohms at 100 MHz with a maximum DC resistance of 0.01 Ohms and a rated current of 3A. The component operates within a temperature range of -40°C to +85°C and features a maximum height of 0.047 inches (1.20 mm).

Feature Summary

• Provides effective high-frequency noise attenuation through a 30 Ohm impedance characteristic at 100 MHz.
• Supports continuous currents up to 3 Amperes with low insertion loss due to a minimal 0.01 Ohm DC resistance.
• Utilizes a compact 0805 surface-mount footprint suitable for space-constrained printed circuit board layouts.

Applications

• Power line filtering in portable electronic devices
• Signal integrity enhancement in consumer electronics
• Noise suppression on data lines within industrial control systems

Procurement Notes

Verify that the specific order matches the Eaton part number MFBM1V2012-300-R to ensure correct impedance and current ratings. Confirm compliance with RoHS directives and check moisture sensitivity levels prior to assembly. Ensure storage conditions align with manufacturer guidelines to maintain component reliability before soldering.

Selection Notes

Select this component when a 30 Ohm impedance at 100 MHz is required for noise suppression in power or signal lines. The 3A current rating makes it suitable for moderate current applications where low DC resistance is critical. Consider the 0805 package size for compatibility with existing board footprints and automated placement equipment.

Part Context

This ferrite bead belongs to Eaton's MFBM1V series, which offers various impedance values in standard SMD packages. The 2012 designation indicates the physical dimensions, while the suffix specifies the electrical characteristics. It serves as a passive filter element to suppress electromagnetic interference in modern electronic circuits.

Replacement Considerations

Direct substitutes include other Eaton MFBM1V series beads with identical 30 Ohm impedance and 0805 packaging, such as MFBM1V2012-301-R if higher impedance is acceptable. Cross-reference with other manufacturers' 0805 ferrite beads ensuring matching current ratings and impedance profiles.
