MFBW1V2012-800-R

Overview

The MFBW1V2012-800-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features an impedance of 80 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current rating of 2.5 A and has a maximum DC resistance of 80 mOhms. Designed for surface mount technology, it utilizes the 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.25 mm width, and 1.0 mm height. The operating temperature range spans from -40°C to +85°C.

Feature Summary

• Multilayer construction provides effective high-frequency noise suppression in compact form factors
• Shielded design minimizes electromagnetic interference coupling to adjacent circuit traces
• Robust current handling capability suitable for power line filtering applications

Applications

• High-speed data line filtering in portable electronic devices
• Power supply output filtering for integrated circuits
• Noise suppression in automotive infotainment systems

Procurement Notes

Verify the specific suffix code to confirm impedance value and current rating, as variations exist within the MFBW1V series. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure storage conditions align with moisture sensitivity levels specified in the datasheet to maintain solderability and electrical performance during assembly processes.

Selection Notes

Select this component when an 80 Ohm impedance at 100 MHz is required for noise attenuation on lines carrying up to 2.5 Amperes. The 0805 footprint offers a balance between current capacity and board space efficiency compared to smaller packages. Evaluate thermal dissipation requirements under continuous load conditions to ensure operation remains within the specified temperature limits.

Part Context

This part belongs to the MFBW1V series of multilayer chip beads from Eaton Electronics. The series is engineered for general-purpose EMI suppression in consumer electronics and industrial equipment. The 2012 case size allows for higher current ratings than smaller 0402 or 0603 variants while maintaining low profile characteristics suitable for modern surface mount assembly techniques.

Replacement Considerations

Cross-reference with MFBW1V2012-101-R if a 100 Ohm impedance is acceptable. Verify that substitute components match the 0805 footprint and meet the 2.5 A current rating requirement. Ensure equivalent shielding characteristics to prevent signal integrity issues in dense PCB layouts.
