MFBM1V1005-070-R

Overview

The Eaton MFBM1V1005-070-R is a multilayer ferrite chip bead designed for EMI suppression in power line applications. It features a 0402 (1005 Metric) surface-mount package with dimensions of 1.00mm x 0.50mm and a maximum height of 0.65mm. The component provides an impedance of 7 Ohms at 100 MHz, with a DC resistance of 50 mOhms maximum. It supports a rated current of 1.8A and operates within a temperature range of -40°C to 85°C.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Single-line power line filtering capability
• Compact 0402 surface-mount footprint for space-constrained designs

Applications

• Power supply input filtering
• DC/DC converter output noise reduction
• General EMI suppression on power lines

Procurement Notes

Verify the specific ordering suffix matches the required impedance value, as variations exist within the MFBM1V1005 series. Confirm that the 0402 package size aligns with the PCB land pattern requirements. Ensure the 1.8A current rating meets the circuit's operational demands without saturation. Check RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a low-profile solution is needed for high-frequency noise attenuation on power traces. The 7 Ohm impedance at 100 MHz targets specific EMI frequencies common in digital circuits. The 1.8A current handling capacity suits moderate-power applications. Consider the 50 mOhm DCR to minimize voltage drop and power loss in the signal path.

Part Context

This part belongs to the Eaton MFB Series of multilayer ferrite chip beads. These components are engineered specifically for EMI suppression in compact electronic devices. The series offers various impedance values and current ratings within standardized packages like 0402, allowing designers to tailor filtering performance to specific circuit requirements while maintaining small form factors.

Replacement Considerations

Direct substitutes include other Eaton MFBM1V1005 variants with matching electrical characteristics. Verify that any replacement maintains the same 0402 package dimensions and 1.8A current rating. Cross-reference impedance curves to ensure equivalent noise suppression performance at target frequencies.
