SFJNC3K00101MC0

Overview

The Knowles Syfer SFJNC3K00101MC0 is a feedthrough capacitor rated at 3000 VDC with a capacitance of 100 pF and a tolerance of ±20%. It utilizes C0G (NP0) dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. The component features an axial bushing package design for panel mounting applications.

Feature Summary

• High voltage insulation capability up to 3000 VDC
• Stable C0G (NP0) dielectric for precision filtering
• Axial bushing mechanical structure for secure panel integration

Applications

• High voltage power supply EMI filtering
• Medical equipment signal conditioning
• Industrial control system noise suppression

Procurement Notes

Verify the specific voltage rating and mechanical dimensions against the official datasheet before integration. Confirm that the axial bushing mounting style aligns with the chassis design requirements. Ensure the operating environment remains within the specified temperature limits to maintain dielectric stability and prevent premature failure.

Selection Notes

Select this component when high DC blocking voltage and low capacitance are required in a single-stage filter configuration. The C0G dielectric offers minimal capacitance variation with temperature and voltage, making it suitable for precision analog circuits. Compare physical dimensions against available panel cutouts to ensure proper fit during assembly.

Part Context

This part belongs to the SFJNC series of feedthrough capacitors from Knowles Syfer. These components are designed for electromagnetic interference suppression in high-voltage environments. The series provides various capacitance values and voltage ratings to suit different filtering needs while maintaining compact form factors for dense packaging.

Replacement Considerations

Check for direct substitutes within the SFJNC series or equivalent axial feedthrough capacitors from other manufacturers. Verify that any replacement matches the 3000 VDC rating, 100 pF capacitance, and C0G dielectric characteristics to ensure circuit compatibility.
