MFBW1V2012-801-R

Overview

The MFBW1V2012-801-R is a multilayer chip ferrite bead from Eaton Electronics, designed for EMI suppression in surface-mount applications. It features an impedance of 800 Ohms at 100 MHz and supports a maximum DC current rating of 800 mA. The component has a maximum DC resistance (DCR) of 300 mOhms and operates within a temperature range of -40°C to +85°C. Housed in a standard 0805 (2012 Metric) package, it provides effective noise filtering for high-density circuit designs.

Feature Summary

• Multilayer construction for compact EMI suppression
• High current handling capability up to 800 mA
• Shielded design to minimize electromagnetic interference

Applications

• Portable electronic devices
• Automotive electronics systems
• Industrial control equipment

Procurement Notes

Verify the specific suffix '801' corresponds to the required 800 Ohm impedance value at 100 MHz. Confirm that the 800 mA current rating and 300 mOhm DCR meet the target circuit requirements. Ensure the 0805 footprint aligns with the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a 0805 package but higher current capacity than smaller footprints allows. The 800 Ohm impedance is suitable for suppressing noise in digital signal lines or power rails where moderate attenuation is needed without excessive voltage drop under load conditions.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics. These components are engineered for high reliability in demanding environments, offering consistent performance across automotive and industrial sectors while maintaining small form factors for modern miniaturized electronics.

Replacement Considerations

Check for direct substitutes within the same Eaton MFBW1V series with identical 0805 dimensions and electrical characteristics. Verify compatibility with other manufacturers' 0805 ferrite beads rated at 800 Ohms @ 100 MHz and 800 mA, ensuring equivalent DCR and temperature stability.
