SFJEC1K00683MX1

Overview

The Knowles Syfer SFJEC1K00683MX1 is an axial lead feedthrough capacitor designed for electromagnetic interference (EMI) filtering. It features a capacitance of 0.068 µF with a tolerance of ±20%. The component has a DC voltage rating of 1 kV and utilizes a C0G/NP0 dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. The device employs a flange end seal construction with solder termination, providing robust mechanical integrity and effective shielding in high-frequency applications.

Feature Summary

• Axial lead configuration with flange end seal for secure panel mounting
• C0G/NP0 dielectric material for high stability and low loss
• High voltage rating of 1 kVDC suitable for demanding environments

Applications

• Electromagnetic interference (EMI) filtering in power supplies
• Signal conditioning in aerospace and defense systems
• High-voltage circuit protection in industrial equipment

Procurement Notes

Verify the specific suffix MX1 against the manufacturer's current datasheet to confirm terminal plating and sealing specifications. Ensure the selected variant matches the required axial lead dimensions and flange geometry for your enclosure design. Confirm RoHS compliance status through official documentation before integration into regulated assemblies.

Selection Notes

Select this component when high voltage isolation and superior EMI attenuation are required in a compact axial form factor. The C0G dielectric ensures minimal capacitance drift under varying thermal conditions. Evaluate the physical footprint requirements against available panel space, as the flange mount necessitates specific hole patterns for proper installation and grounding.

Part Context

This part belongs to the SFJN series of feedthrough capacitors from Knowles Syfer. These components are engineered for high-reliability applications where traditional surface-mount or through-hole capacitors may fail due to environmental stress or frequency limitations. The series emphasizes robust construction and consistent electrical performance in harsh operating conditions.
