MFBW1V2012-190-R

Overview

The MFBW1V2012-190-R is a shielded multilayer ferrite bead manufactured by Eaton Electronics, designed for surface-mount technology (SMT) applications. It features an 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.2 mm width, and 0.8 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 rating of 3 A and has a maximum DC resistance of 30 mOhms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Shielded multilayer construction minimizes electromagnetic interference coupling.
• High current handling capability suitable for power line filtering.
• Compact SMD footprint optimized for space-constrained PCB layouts.

Applications

• EMI suppression in portable electronic devices
• Signal integrity protection in high-speed data lines
• Power distribution network filtering in consumer electronics

Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation to confirm reel packaging specifications and tape-and-reel parameters. Ensure that the requested quantity aligns with standard factory pack sizes or cut-tape availability requirements. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when a 19 Ohm impedance at 100 MHz is required for EMI suppression in circuits carrying up to 3 Amperes. The 0805 package size offers a balance between current capacity and board space efficiency compared to smaller footprints. Consider the low DC resistance value to minimize voltage drop and power loss in power-sensitive applications.

Part Context

This part belongs to the MFBW1V series of multilayer chip beads from Eaton Electronics. The series utilizes proprietary materials to provide effective noise attenuation across a broad frequency spectrum while maintaining stability under varying thermal conditions. The MFBW1V designation indicates a specific formulation optimized for shielding and high-current performance in modern electronic assemblies.

Replacement Considerations

MFBM1V2012-110-R is a related variant within the same package family but differs significantly in impedance and current rating. Verify electrical compatibility carefully before substitution, as the 11 Ohm impedance and 6A rating are not interchangeable with the 19 Ohm/3A specifications of the target part.
