MFBW1V1005-050-R

Overview

The MFBW1V1005-050-R is a multilayer ferrite chip bead manufactured by Eaton Electronics Division, designed for electromagnetic interference (EMI) suppression in electronic circuits. Housed in a compact 0402 (1005 metric) surface-mount package, this component provides an impedance of 5 ohms at a frequency of 100 MHz. It features a maximum DC resistance of 40 milliohms and supports a rated current of up to 800 mA. The device operates reliably within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Multilayer construction enables effective high-frequency noise attenuation in compact form factors
• Low DC resistance minimizes power loss and voltage drop in signal paths
• Surface-mount design facilitates automated assembly and space-constrained PCB layouts

Applications

• High-speed data line filtering in portable electronics
• Power supply output decoupling for integrated circuits
• RF circuit noise suppression in communication modules

Procurement Notes

Verify the specific impedance value of 5 ohms at 100 MHz against circuit requirements. Confirm the 800 mA current rating suffices for the application's peak load. Ensure the 0402 footprint matches the PCB layout. Check RoHS3 compliance status if required by regional regulations. Validate supplier authenticity through authorized distribution channels.

Selection Notes

Select this component when low inductance and minimal insertion loss are critical alongside moderate EMI suppression. The 0402 size suits dense board designs where larger beads cannot fit. Consider the 800 mA limit for power integrity; higher current applications may require parallel configurations or larger packages. Evaluate thermal performance under continuous load conditions.

Part Context

This part belongs to the MFBW1V1005 series of multilayer ferrite beads from Eaton Electronics. The series offers various impedance values tailored for different filtering needs while maintaining consistent physical dimensions. These components are engineered for general-purpose EMI suppression in consumer, industrial, and automotive electronics requiring reliable noise control.

Replacement Considerations

Cross-reference with other 0402 ferrite beads offering 5 ohms impedance at 100 MHz. Verify equivalent current ratings and DC resistance specifications. Ensure mechanical compatibility with existing footprints. Confirm material composition meets environmental compliance standards.
