Procurement Notes

Verify the specific package dimensions and electrical parameters against the official Eaton Electronics datasheet before integration. Confirm RoHS compliance status and lead-free characteristics as required by your manufacturing standards. Ensure the selected supplier provides authentic components with traceable documentation to maintain supply chain integrity and product reliability.

Selection Notes

Select this component when a 70 Ohm impedance at 100 MHz is required for EMI suppression in space-constrained designs. The 0805 footprint offers a balance between performance and board area. Consider the 2.5 A current rating to ensure adequate headroom for the application's peak load requirements without saturation or excessive heating.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite beads designed for high-current applications. Eaton Electronics produces this series to provide reliable EMI suppression solutions in compact surface-mount packages. The MFBW1V series is widely used in consumer electronics and industrial equipment where noise reduction on power lines is critical.

Replacement Considerations

Cross-reference with other 0805 ferrite beads offering 70 Ohms impedance and similar current ratings. Verify that any substitute matches the 80 mOhms DC resistance and operating temperature range. Consult Eaton Electronics for approved alternative part numbers if availability is constrained.
