MFBW1V3216-801-R

Overview

The Eaton MFBW1V3216-801-R is a single-line multilayer ferrite chip bead designed for surface mount applications. It features an impedance of 800 Ohms at 100 MHz and supports a maximum current rating of 2A. The component has a maximum DC resistance (DCR) of 250 milliohms. It is housed in a 1206 (3216 Metric) package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.10mm. The device operates within a temperature range of -40°C to 85°C.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• High current handling capability suitable for power line filtering
• Compact surface mount footprint for dense circuit board layouts

Applications

• EMI suppression on high-speed digital signal lines
• Power supply input/output filtering
• Noise reduction in portable electronic devices

Procurement Notes

Verify the specific impedance tolerance, which is typically ±25% for this series, against design requirements. Confirm that the 2A current rating aligns with peak operational loads to prevent saturation. Ensure the 1206 package dimensions fit the designated PCB land pattern. Check RoHS3 compliance status if required by project specifications.

Selection Notes

Select this component when high impedance at 100 MHz is required for noise attenuation. The 2A rating distinguishes it from lower-current variants in the MFBW1V3216 series. Consider the 250mOhm DCR impact on voltage drop in low-voltage circuits. Compare with other ferrite beads if higher current or different impedance profiles are needed.

Part Context

This part belongs to the Eaton MFBW1V3216 series of multilayer ferrite chip beads. The series offers various impedance values while maintaining consistent physical dimensions and current ratings. These components are engineered for EMI suppression in compact electronic designs requiring reliable performance across industrial temperature ranges.

Replacement Considerations

Compatible substitutes include other 1206 ferrite beads with 800 Ohms @ 100 MHz impedance and ≥2A current ratings. Verify pin compatibility and thermal characteristics before substitution.
