MFBM1V2012-500-R

Overview

The MFBM1V2012-500-R is a multilayer chip ferrite bead from Eaton Electronics, designed for EMI suppression in single-line power applications. It features an impedance of 50 Ohms at 100 MHz and supports a maximum DC current of 3.5 A. The component has a maximum DC resistance of 40 mOhms and operates within a temperature range of -40°C to +85°C. Housed in an 0805 (2012 metric) surface-mount package with dimensions of 2.0 mm length, 1.2 mm width, and 1.0 mm height, it provides effective noise filtering for compact electronic designs.

Feature Summary

• Multilayer construction for high-current handling capabilities
• Single-line configuration for power supply noise suppression
• Surface-mount design for automated assembly integration

Applications

• Power line filtering in portable electronics
• EMI suppression in automotive infotainment systems
• Noise reduction in industrial control circuits

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official Eaton datasheet prior to procurement. Confirm that the 0805 package dimensions align with the target PCB footprint. Ensure the selected supplier provides components compliant with RoHS3 standards and appropriate moisture sensitivity level classifications for storage and reflow soldering processes.

Selection Notes

Select this component when a 50 Ohm impedance at 100 MHz is required for single-line power filtering. The 3.5 A current rating makes it suitable for higher-power applications compared to smaller packages. Consider the 40 mOhm DCR for voltage drop calculations in low-voltage circuits. Verify thermal performance under continuous load conditions within the specified operating temperature range.

Part Context

This part belongs to the MFBM1V series of multilayer ferrite beads from Eaton Electronics. The series offers various impedance and current ratings across different package sizes, including 0402, 0603, and 0805. The MFBM1V2012 variant specifically targets applications requiring robust current handling in a compact surface-mount form factor.

Replacement Considerations

Cross-reference with other Eaton MFBM1V2012 variants such as MFBM1V2012-600-R for different impedance requirements. Verify compatibility with alternative manufacturers' 0805 ferrite beads offering similar 50 Ohm impedance and 3.5 A current ratings.
