MFBW1V3216-221-R

Overview

The Eaton MFBW1V3216-221-R is a single-line multilayer chip ferrite bead in a 1206 (3216 metric) surface-mount package. It provides an impedance of 220 Ohms at 100 MHz with a maximum DC current rating of 2.5 A and a maximum DC resistance of 120 mOhms. The component operates within a temperature range of -40°C to +85°C and features a shielded design.

Feature Summary

• Multi-normal curve characteristic for stable performance across varying current loads
• Shielded construction to minimize electromagnetic interference coupling
• Compact 1206 footprint suitable for high-density PCB layouts

Applications

• High-speed data line filtering
• Power supply noise suppression
• RF circuit protection

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the impedance tolerance is ±25% against schematic requirements. Ensure the 2.5A current rating meets the application's peak load demands. Check RoHS compliance status if required by regulatory standards. Validate the 1206 package dimensions fit the designated footprint.

Selection Notes

Select this component when 220 Ohms attenuation at 100 MHz is required. The 2.5A rating suits moderate current applications. Consider the 120mOhm DCR for voltage drop calculations. The shielded type reduces crosstalk compared to unshielded variants. Verify thermal stability up to 85°C for the operating environment.

Part Context

This part belongs to the Eaton MFBW1V series of multilayer chip ferrite beads. The series offers various impedance values in standardized SMD packages. The 3216 designation refers to the 1206 inch-based package size. These components are designed for EMI suppression in electronic circuits.

Replacement Considerations

Cross-reference other MFBW1V3216 variants with matching 220 Ohm impedance and 2.5A current ratings. Verify identical package dimensions and pin configurations before substitution. Ensure replacement parts meet the same temperature and shielding specifications.
