Overview
The MFBW1V1005-310-R is a surface-mount ferrite bead manufactured by Eaton Electronics Division. It features an impedance of 31 ohms at 100 MHz and supports a maximum current rating of 700 mA. The component utilizes a 0402 (1005 Metric) package size with a low DC resistance of 80 milliohms. This single-line device is designed for high-frequency noise suppression in compact electronic circuits.
Feature Summary
- Provides multi-noise curve performance for effective signal integrity management
- Utilizes a compact 0402 surface-mount footprint for space-constrained designs
- Offers low DC resistance to minimize power loss in the circuit path
Applications
- High-speed data line filtering
- Power supply noise suppression
- RF circuit interference reduction
Procurement Notes
Verify the complete part number including the suffix -R, which indicates reel packaging, against official Eaton documentation. Confirm the specific impedance tolerance and current ratings match the design requirements before ordering. Ensure the supplier provides valid traceability documents consistent with the manufacturer's standards for this electronic component series.
Selection Notes
Select this component when a 31-ohm impedance at 100 MHz is required within a 0402 package. The 700 mA current rating must align with the operational load of the target circuit. Consider the low DC resistance value to ensure minimal voltage drop across the filter element during normal operation.
Part Context
This ferrite bead belongs to the MFBW1V1005 series from Eaton Electronics Division. The series offers various impedance values within the same 0402 form factor, allowing designers to customize noise suppression characteristics without altering the board layout dimensions significantly.
Replacement Considerations
Cross-reference with other Eaton MFBW1V1005 variants such as MFBW1V1005-190-R or MFBW1V1005-301-R if different impedance or current specifications are needed. Verify pin compatibility and thermal characteristics before substituting.
