MFBW1V3216-260-R

Overview

The Eaton MFBW1V3216-260-R is a multilayer chip ferrite bead designed for surface-mount technology (SMT) applications. It operates within a temperature range of -40°C to +85°C and features a 1206 package size measuring 3.2 mm in length, 1.6 mm in width, and 0.9 mm in height. The component provides an impedance of 26 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 3.0 A and has a maximum DC resistance of 50 mOhms.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Shielded design to contain magnetic fields
• High current handling capability suitable for power line filtering

Applications

• Power supply output filtering
• DC-DC converter noise suppression
• General-purpose EMI suppression in electronic circuits

Procurement Notes

Verify the specific impedance value and current rating against circuit requirements before ordering. Confirm that the 1206 package dimensions align with the PCB footprint. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when low impedance at high frequencies is needed alongside significant DC current capacity. The 26 Ohm impedance offers moderate attenuation for broadband noise. Consider the 50 mOhms DC resistance impact on voltage drop. The shielded type minimizes inductive coupling to nearby components compared to unshielded variants.

Part Context

This part belongs to the Eaton MFBW1V series of multilayer ferrite beads. These components are engineered for compact SMT layouts. The series offers various impedance values tailored for different noise profiles. The 1206 form factor balances performance with space constraints in modern electronics.

Replacement Considerations

Direct substitutes include other Eaton MFBW1V3216 variants with similar impedance, such as MFBW1V3216-280-R. Cross-brand replacements must match the 1206 package, 26 Ohm impedance, and 3A current rating. Verify thermal characteristics and shielding properties during substitution.
