MFBW1V2012-181-R

Overview

The Eaton MFBW1V2012-181-R is a multilayer chip ferrite bead in an 0805 (2012 metric) surface-mount package. It provides 180 Ohms impedance at 100 MHz with a maximum DC current rating of 2 Amperes. The component features a maximum DC resistance of 150 mOhms and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer construction for compact high-frequency noise suppression
• Shielded design to minimize electromagnetic interference
• High thermal stability across extended industrial temperature ranges

Applications

• High-speed data line filtering
• Power supply output decoupling
• Clock signal noise attenuation

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the 0805 footprint matches the target PCB layout constraints. Validate that the 2A current rating meets the circuit's peak operational requirements without saturation.

Selection Notes

Select this component when space-constrained designs require effective broadband noise reduction. The 180 Ohm impedance value targets specific frequency bands around 100 MHz. The 2A current handling capability supports moderate power applications. Compare against alternative impedances if the target noise spectrum differs significantly from the specified characteristic.

Part Context

This part belongs to the Eaton MFBW1V series of multilayer chip beads. The series offers various impedance values and current ratings in standard SMT packages. The MFBW1V2012 variant specifically addresses needs for balanced performance between size and current capacity in consumer and industrial electronics.

Replacement Considerations

Cross-reference with other 0805 ferrite beads offering 180 Ohms at 100 MHz and 2A current. Verify equivalent DC resistance and temperature coefficients. Ensure physical dimensions match exactly for direct replacement without PCB modification.
