MFBM1V3216-070-R

Overview

The Eaton MFBM1V3216-070-R is a multilayer ferrite chip bead designed for electromagnetic interference (EMI) suppression in surface-mount applications. It features a shielded construction within a 1206 (3216 metric) package, measuring 3.2 mm in length, 1.6 mm in width, and 0.9 mm in height. The component provides an impedance of 7 Ohms at a test frequency of 100 MHz, with a tolerance range of 0 to 11 Ohms. It supports a maximum DC current of 4 A and exhibits a maximum DC resistance of 40 mOhms. The device operates reliably within a temperature range of -40°C to +85°C.

Feature Summary

• Shielded multilayer construction minimizes external magnetic field radiation.
• High current handling capability suitable for power line filtering.
• Low DC resistance reduces power loss in signal paths.

Applications

• Electromagnetic interference suppression on high-current data lines
• Power supply input filtering for portable electronics
• Signal integrity protection in industrial control systems

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm impedance tolerance and current ratings. Ensure the procurement channel sources components directly from authorized distributors to guarantee authenticity. Confirm RoHS compliance status and environmental certifications prior to finalizing orders, as regulatory requirements may vary by region and production batch.

Selection Notes

Select this component when shielding is required to prevent magnetic coupling with adjacent circuitry. The 4 A current rating makes it appropriate for power distribution networks rather than low-power signal lines. Compare the 7 Ohm impedance specification against target noise frequencies to ensure effective attenuation. Consider the 1206 footprint compatibility with existing PCB layouts during the design phase.

Part Context

This part belongs to the MFBM1V series of multilayer ferrite beads manufactured by Eaton Electronics Division. The series is engineered for EMI suppression in compact electronic devices. The MFBM1V3216-070-R specifically utilizes a shielded architecture to contain magnetic fields, distinguishing it from unshielded variants within the broader ferrite bead product family.
