MFBM1V1005-700-R

Overview

The MFBM1V1005-700-R is a single-line power line ferrite bead manufactured by Eaton - Electronics Division. 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 70 Ohms at 100 MHz and has a maximum DC resistance of 150 milliohms. It supports a rated current of 800mA and operates within a temperature range of -40°C to 85°C.

Feature Summary

• Multilayer chip construction for effective electromagnetic interference suppression
• Designed specifically for power line noise filtering applications
• RoHS3 compliant and lead-free manufacturing process

Applications

• Power supply input filtering
• DC/DC converter output noise reduction
• High-speed digital circuit EMI suppression

Procurement Notes

Verify the specific impedance value and current rating against the official Eaton datasheet before integration, as suffixes may indicate variations. Confirm that the 0402 footprint matches the PCB layout requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check for RoHS3 compliance if required by regional regulations.

Selection Notes

Select this component when a compact 0402 form factor is required for power line filtering. The 70 Ohm impedance at 100 MHz targets specific high-frequency noise profiles. The 800mA current rating must exceed the maximum continuous current of the protected circuit to prevent saturation or excessive heating. Compare DCR values to ensure minimal voltage drop in the power path.

Part Context

This part belongs to the MFBM1V1005 series of multilayer ferrite chip beads from Eaton. The series offers various impedance options within the same 0402 package size, allowing designers to tailor noise suppression characteristics without changing the physical footprint. These components are widely used in portable electronics and industrial equipment requiring reliable EMI control.

Replacement Considerations

Cross-reference with other Eaton MFBM1V1005 variants such as MFBM1V1005-300-R or MFBM1V1005-800-R for different impedance levels. Verify that substitute parts maintain the same 0402 dimensions and 800mA current handling capability to ensure mechanical and electrical compatibility.
