Overview
The MFBW1V2012-101-R is a multilayer ferrite chip bead manufactured by Eaton Electronics Division, designed for electromagnetic interference (EMI) suppression. It features an impedance of 100 Ohms measured at a test frequency of 100 MHz and supports a maximum DC current rating of 2.5 Amperes. The component exhibits a maximum DC resistance of 100 milliohms and operates within a temperature range of -40°C to +85°C. Housed in a standard 0805 (2012 Metric) surface-mount package, it provides effective noise filtering for high-current applications.
Feature Summary
- Multilayer ferrite construction optimized for EMI suppression
- High current handling capability up to 2.5A
- Standard 0805 surface-mount footprint
Applications
- Power supply line filtering
- Signal line noise suppression
- Automotive electronics protection
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official Eaton datasheet prior to integration. Confirm that the selected package size aligns with the PCB land pattern requirements. Ensure the operating current does not exceed the rated 2.5A limit to maintain performance integrity. Cross-reference the RoHS compliance status with project specifications.
Selection Notes
Select this component when a 100 Ohm impedance at 100 MHz is required for noise attenuation in circuits carrying up to 2.5 Amperes. The 0805 package offers a balance between current capacity and board space efficiency. Consider thermal dissipation capabilities if the ambient temperature approaches the upper operational limit of 85°C.
Part Context
This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics Division. The series is engineered for general-purpose EMI suppression in compact electronic designs. The '101' suffix denotes the specific impedance characteristic, while '2012' indicates the metric package dimensions.
Replacement Considerations
Direct substitutes include other 0805 ferrite beads with similar 100 Ohm impedance and current ratings. Verify equivalent impedance curves and saturation characteristics before substitution.
