MFBW1V2012-102-R

Overview

The MFBW1V2012-102-R is a multilayer chip ferrite bead from Eaton Electronics, designed for high-frequency noise suppression. It features an impedance of 1000 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 800 mA. The component has a maximum DC resistance of 300 mOhms and operates within a temperature range of -40°C to +85°C. Housed in a compact 0805 (2012 metric) surface-mount package with dimensions of 2.0 mm x 1.2 mm x 1.0 mm, it provides effective electromagnetic interference filtering for portable electronic devices.

Feature Summary

• Multilayer chip construction for reliable high-frequency noise attenuation
• Compact 0805 surface-mount footprint suitable for space-constrained designs
• Capable of handling up to 800 mA DC current without saturation

Applications

• Noise suppression in portable consumer electronics
• Signal line filtering in mobile communication devices
• EMI reduction in compact digital circuits

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official Eaton datasheet prior to integration. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Ensure the surface-mount package dimensions align with the PCB land pattern design to guarantee proper soldering and mechanical stability during operation.

Selection Notes

Select this component when a 1 kOhm impedance at 100 MHz is required for EMI suppression in low-profile applications. The 800 mA current rating makes it suitable for power lines or signal paths carrying moderate currents. Consider the 0805 package size if board real estate is limited but higher current capacity than smaller packages is needed.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics. The series offers various impedance and current ratings in standard SMD packages. These components are engineered to provide broadband noise absorption while maintaining low DC resistance, making them essential for maintaining signal integrity in modern high-speed digital systems.

Replacement Considerations

Cross-reference with other Eaton MFBW1V series parts for different impedance levels. Verify equivalent performance from other manufacturers offering 0805 ferrite beads with similar 1000 Ohm @ 100 MHz specifications and 800 mA current ratings.
