Procurement Notes

Verify the current lifecycle status before procurement, as this specific part number may be marked as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors, noting that shipping restrictions or limited stock may apply. Ensure the selected variant matches the required 680 pF capacitance and 100 VDC rating for your specific circuit application.

Selection Notes

Select this component when a low-profile, three-terminal feed-through capacitor is required for high-frequency noise reduction. The 2.54mm pitch compatibility simplifies integration into existing through-hole designs. Consider the X7R dielectric stability and 100 VDC rating to ensure reliable operation under expected electrical loads and temperature conditions.

Part Context

This component belongs to the Murata DSS1 series, which specializes in compact, high-performance lead-type capacitors. The series is engineered to provide efficient electromagnetic interference filtering while maintaining a small footprint suitable for dense electronic assemblies. The three-terminal architecture distinguishes it from standard two-terminal capacitors by offering superior grounding and signal path isolation.

Replacement Considerations

Check for direct substitutes within the DSS1 series that match the 680 pF value and Q55B package. Verify that any replacement maintains the 2.54mm pitch and 100 VDC rating. Consult official Murata documentation for cross-reference lists to ensure functional equivalence.
