Overview
The Eaton MFBW1V2012-070-R is a multilayer chip ferrite bead designed for surface mount technology. It operates within a temperature range of -40°C to +85°C and features an impedance of 7 Ohms at a test frequency of 100 MHz. The component has a maximum DC current rating of 1 Ampere and a maximum DC resistance of 30 milliohms. Its physical dimensions are 2.0 mm in length, 1.2 mm in width, and 0.9 mm in height, conforming to the 0805 (2012 metric) package standard.
Feature Summary
- Multilayer construction provides effective high-frequency noise suppression
- Shielded design minimizes electromagnetic interference
- Compact SMD form factor suitable for space-constrained PCB layouts
Applications
- High-speed data line filtering
- Power supply noise attenuation
- Signal integrity enhancement in digital circuits
Procurement Notes
Verify the manufacturer part number against official Eaton documentation to ensure authenticity. Confirm that the specific suffix matches the required impedance and current ratings. Check RoHS compliance status through authorized channels. Ensure storage conditions align with manufacturer guidelines to maintain component integrity prior to assembly.
Selection Notes
Select this component when a low impedance value of 7 Ohms is required for noise filtering at 100 MHz. The 1A current rating suits moderate power applications. The 0805 package allows for automated placement. Verify that the 30mOhm DCR meets the voltage drop constraints of the target circuit design.
Part Context
This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics Division. The series offers various impedance values and current ratings in standardized packages. This specific model represents the 0805 footprint variant optimized for general-purpose EMI suppression in consumer and industrial electronics.
Replacement Considerations
Compatible substitutes include MFBW1V2012-090-R and MFBW1V2012-310-R from the same Eaton series. Cross-reference impedance and current ratings before substitution.
