MFBM1V3216-190-R

Overview

The Eaton MFBM1V3216-190-R is a multilayer chip ferrite bead designed for electromagnetic interference (EMI) suppression in surface-mount applications. It features a 1206 package with dimensions of 3.2 mm length, 1.6 mm width, and 0.9 mm height. The component provides an impedance of 19 Ohms at a test frequency of 100 MHz, with a tolerance range of 12 to 25 Ohms. It supports a maximum DC current of 6 A and has a maximum DC resistance of 15 mOhms. Operating temperatures range from -40°C to +85°C.

Feature Summary

• High current handling capability suitable for power line filtering
• Shielded construction to minimize magnetic field radiation
• Multilayer ceramic technology for compact SMT integration

Applications

• Power supply output filtering
• DC-DC converter noise suppression
• High-speed digital signal line protection

Procurement Notes

Verify the specific impedance value and current rating against the official Eaton datasheet before procurement. Confirm that the 1206 footprint matches the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when high DC current capacity is required alongside EMI suppression. The 19 Ohm impedance offers moderate attenuation at 100 MHz. Compare the 6 A rating against circuit load requirements to prevent saturation. Consider the low DC resistance to minimize voltage drop and power loss in the signal path.

Part Context

This part belongs to the MFBM1V series of multilayer ferrite beads from Eaton Electronics. The series is characterized by shielded designs and high current ratings. It complements other variants in the family that offer different impedance values or current capacities within the same 1206 package form factor.

Replacement Considerations

Check for direct substitutes within the MFBM1V series with matching impedance and current ratings. Verify pin compatibility and thermal characteristics before substituting with components from other manufacturers.
