Procurement Notes

Verify the specific suffix codes against official Murata documentation to ensure correct voltage and capacitance ratings. Confirm that the 1206 package dimensions align with your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Ensure the 10 A current rating meets your circuit's operational requirements to prevent thermal issues.

Selection Notes

Select this component when high current handling capability is required alongside EMI filtering. The 100 VDC rating makes it suitable for various power rail applications. Consider the 1.5 mOhm resistance for minimal voltage drop across the filter. The 1206 footprint offers a balance between performance and board space compared to larger packages.

Part Context

This part belongs to Murata's NFM series of feed-through capacitors, which are engineered for superior high-frequency noise suppression. These components integrate ceramic dielectric technology with a unique internal structure to minimize parasitic inductance. The series is widely used in consumer electronics, automotive systems, and industrial equipment requiring robust EMI protection.

Replacement Considerations

Consult official Murata substitution guides for compatible alternatives. Verify that any substitute matches the 1206 footprint, 100 VDC rating, and 10 A current capacity. Ensure equivalent capacitance and impedance characteristics to maintain circuit performance.
