MFBM1V2012-800-R

Overview

The MFBM1V2012-800-R is a multilayer chip ferrite bead manufactured by Eaton Electronics Division, designed for electromagnetic interference (EMI) suppression in single-line power applications. Housed in a compact 0805 (2012 metric) surface-mount package, this component provides an impedance of 80 Ohms at a test frequency of 100 MHz. It supports a maximum DC current rating of 3.0 A with a maximum DC resistance (DCR) of 40 mOhms. The device operates within a temperature range of -40°C to +85°C and features a tolerance of ±25% on its impedance value.

Feature Summary

• Multilayer construction for effective high-frequency noise attenuation
• High current handling capability suitable for power line filtering
• Low DC resistance minimizes voltage drop and power loss
• Compact surface-mount footprint for dense PCB layouts

Applications

• Power supply output filtering
• Data line EMI suppression
• General-purpose noise reduction in electronic circuits

Procurement Notes

Verify the specific impedance value and current rating against the target circuit requirements before ordering. Confirm that the 0805 package dimensions align with the PCB land pattern. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check for RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when a balance between high current capacity and moderate impedance is required in a small form factor. The 80 Ohm impedance at 100 MHz targets common noise frequencies. Consider the 40 mOhm DCR to ensure minimal impact on signal integrity or power delivery efficiency. Compare with other series members if higher current or different impedance characteristics are needed.

Part Context

This part belongs to the MFBM1V series of multilayer ferrite beads from Eaton Electronics. The series offers various impedance values and current ratings across standard packages like 0402, 0603, and 0805. These components are engineered for reliable EMI suppression in consumer electronics, industrial equipment, and automotive applications where space is limited.

Replacement Considerations

Direct substitutes include other Eaton MFBM1V series parts with similar impedance and current ratings, such as MFBM1V2012-101-R for higher impedance. Cross-brand equivalents should match the 0805 package, 80 Ohm @ 100 MHz impedance, and 3.0 A current rating.
