Procurement Notes
This component is officially listed as discontinued by the manufacturer. Availability is restricted to existing stock or secondary market sources. Verify end-of-life status and last-time buy dates through authorized distributors before integration into new designs. Ensure supply chain stability for maintenance or replacement cycles given the obsolete production status.
Selection Notes
Select this part for applications requiring small form factor EMI filtering with specific 47 pF capacitance. Consider the 1806 footprint constraints and 100 VDC rating. Evaluate thermal performance within the specified temperature range. Confirm compatibility with surface-mount reflow soldering profiles and verify that the three-terminal grounding scheme fits the PCB layout requirements.
Part Context
Part of the Murata EMIFIL NFM41C series of three-terminal feedthrough capacitors. These components are designed for high-performance noise suppression in space-constrained environments. The series offers various capacitance values within the same physical package dimensions, allowing for standardized board layouts across different filtering requirements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative sourcing requires verification of equivalent electrical parameters and mechanical dimensions from other manufacturers.
