MFBM1V2012-102-R

Overview

The Eaton MFBM1V2012-102-R is a multilayer chip ferrite bead in the MFBM1V series, designed for surface-mount technology. It features a 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.25 mm width, and 1.2 mm height. The component provides an impedance of 1 kOhm at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 1.5 A and has a maximum DC resistance of 120 mOhms. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Multilayer construction for high-density PCB integration
• Shielded design to minimize electromagnetic interference
• Single-channel configuration for power line filtering

Applications

• Power line noise suppression in electronic circuits
• EMI filtering for portable devices
• Signal integrity enhancement in consumer electronics

Procurement Notes

Verify the specific impedance value and current rating against the official Eaton datasheet before procurement. Confirm that the 0805 footprint matches the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a 1 kOhm impedance at 100 MHz is required for power lines carrying up to 1.5 A. The 0805 package size offers a balance between performance and board space. Consider the low DC resistance to minimize voltage drop and power loss in high-current applications compared to higher-resistance alternatives.
