SFCDC5000473MX1

Overview

The Knowles Syfer SFCDC5000473MX1 is an EMI feedthrough filter capacitor belonging to the SFCD series. It features a C-filter circuit topology with a capacitance of 47 nF and a voltage rating of 500 VDC. The component utilizes X7R dielectric material with a tolerance of ±20%. It supports a maximum DC current of 10 A and operates within a temperature range of -55°C to +125°C. The physical package includes a bulk configuration with a diameter of 6.35 mm, length of 11.8 mm, lead diameter of 0.7 mm, and a thread size of 12-32.

Feature Summary

• Provides electromagnetic interference suppression through integrated feedthrough filtering architecture
• Utilizes robust X7R ceramic dielectric for stable performance across wide temperature variations
• Designed for high-current applications with a rated capacity of 10 A DC

Applications

• Electromagnetic interference filtering in electronic circuits
• Power supply line conditioning for high-voltage systems
• Industrial equipment requiring reliable signal integrity under thermal stress

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm exact packaging and terminal configurations. Ensure compatibility with existing panel mounting requirements given the threaded design. Cross-reference the 12-32 thread specification with mating hardware. Confirm RoHS and REACH compliance status via official datasheets before integration into regulated assemblies.

Selection Notes

Select this component when a feedthrough capacitor with 47 nF capacitance and 500 VDC rating is required. The 10 A current handling capability suits power distribution lines. The X7R temperature coefficient ensures stability in environments ranging from -55°C to +125°C. The threaded mechanical interface dictates panel-mount installation rather than surface mount or standard through-hole PCB assembly.
