Overview
The MFBW1V2012-202-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features an impedance of 2000 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 300 mA. The component has a maximum DC resistance of 500 mOhms and operates within a temperature range of -40°C to +85°C. It utilizes a shielded SMD/SMT construction in an 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.2 mm width, and 1.2 mm height.
Feature Summary
- Multilayer chip construction for high-frequency noise suppression
- Shielded design to minimize electromagnetic interference
- Surface-mount technology compatible termination
Applications
- High-speed data line filtering
- Power supply noise attenuation
- RF circuit signal integrity maintenance
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official Eaton datasheet prior to integration. Confirm that the 300 mA current rating aligns with the target circuit's operational requirements. Ensure the 0805 footprint matches the PCB layout specifications. Check for RoHS compliance status if required by project standards.
Selection Notes
Select this component when a 2000 Ohm impedance at 100 MHz is required for noise suppression in space-constrained designs. The 0805 package offers a balance between current handling capability and board real estate efficiency compared to smaller footprints. Consider the 500 mOhms DC resistance impact on voltage drop for low-voltage applications.
Part Context
This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics. The series provides various impedance and current ratings across different standard packages. The MFBW1V2012-202-R specifically addresses needs for moderate current handling with high impedance characteristics in compact electronic assemblies.
Replacement Considerations
Cross-reference with other Eaton MFBW1V series parts or equivalent ferrite beads from other manufacturers offering 2000 Ohms @ 100 MHz in an 0805 package. Verify identical impedance curves, current ratings, and physical dimensions before substitution.
