MFBM1V3216-280-R

Overview

The MFBM1V3216-280-R is a single-line multilayer ferrite chip bead from Eaton Electronics Division, designed for EMI suppression in surface-mount applications. It features a 1206 (3216 metric) package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.10mm. The component provides an impedance of 28 Ohms at 100 MHz with a tolerance of ±25%. It supports a maximum current rating of 6A and has a maximum DC resistance (DCR) of 15 mOhm. The device operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Multilayer construction for effective high-frequency noise attenuation
• High current handling capability suitable for power line filtering
• Compact surface-mount footprint for dense PCB layouts

Applications

• Power supply output filtering
• Battery charger circuits
• Portable electronic devices
• Energy-efficient system power lines

Procurement Notes

Verify the specific impedance value and current rating against the latest official datasheet before integration. Confirm that the 1206 package dimensions align with the target PCB land pattern. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check for RoHS3 compliance documentation if required by regulatory standards.

Selection Notes

Select this component when a low DC resistance is critical to minimize voltage drop in high-current paths. The 28 Ohm impedance at 100 MHz targets specific noise frequencies common in switching regulators. Compare against alternative ferrite beads with similar current ratings but different impedance profiles to ensure optimal noise suppression without affecting signal integrity or power efficiency.

Part Context

This part belongs to the MFBM1V3216 series of multilayer ferrite chips. The series offers various impedance values while maintaining consistent physical dimensions and current handling capabilities. It is manufactured by Eaton Electronics Division, a provider of electronic components for industrial and consumer markets.

Replacement Considerations

Direct substitutes include other MFBM1V3216 variants with different impedance values, such as MFBM1V3216-221-R or MFBM1V3216-700-R, if the noise profile differs. Cross-brand replacements must match the 1206 package, 6A current rating, and 28 Ohm @ 100 MHz impedance specifications.
