The component is rated for a maximum DC voltage of 100 V and supports a current rating of 6 A. Designed for through-hole mounting, it operates within a temperature range of -40°C to +85°C. The package dimensions are 8.5 mm in length, 3.5 mm in width, and 7.5 mm in height.

Feature Summary

• Integrates a built-in bead for enhanced high-frequency noise suppression
• Provides low-impedance grounding via three-terminal radial configuration
• Supports high-current applications up to 6 A

Applications

• General EMI/RFI filtering
• Power line noise suppression
• Signal line protection

Procurement Notes

Verify component authenticity against official Murata documentation due to End-of-Life status. Confirm RoHS compliance and specific lot codes during acquisition. Ensure sourcing channels provide valid traceability records. Check for alternative availability as discontinuation may affect long-term supply stability.

Selection Notes

Select this component for circuits requiring compact, high-current EMI filtration. The 47 pF value targets high-frequency interference. Verify that the 100 VDC rating meets circuit voltage requirements. Ensure mechanical fit within the 8.5 x 3.5 x 7.5 mm footprint constraints.

Part Context

This part belongs to the Murata EMIFIL DSS1 series of leaded three-terminal capacitors. These components utilize LC(T) filter technology to combine capacitance with an integrated ferrite bead. The series is designed for effective attenuation of electromagnetic interference in space-constrained electronic assemblies.

Replacement Considerations

Official sources indicate this model is scheduled for obsolescence. Consult Murata for confirmed substitute part numbers within the same series or functional equivalents before finalizing design implementations.
