SFJEL2K00103MX1

Overview

The Knowles Syfer SFJEL2K00103MX1 is a discontinued EMI feedthrough capacitor featuring a 2 kVDC voltage rating and 10 nF capacitance. It utilizes X7R dielectric material with a ±20% tolerance. The component supports a maximum DC current of 15 A and operates within a temperature range of -55°C to +125°C. It provides 43 dB attenuation at 100 MHz and employs an axial bushing mounting style.

Feature Summary

• High-voltage insulation capability for robust electrical isolation
• Effective electromagnetic interference suppression through certified attenuation levels
• Thermal stability maintained across extended industrial operating temperatures

Applications

• Power supply input filtering in high-voltage systems
• Electromagnetic compatibility enhancement in industrial control panels
• Signal integrity protection in sensitive electronic instrumentation

Procurement Notes

This component is officially discontinued and no longer manufactured by Knowles Syfer. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Confirm end-of-life status and substitute part numbers before finalizing procurement plans to ensure long-term supply chain stability.

Selection Notes

Designers requiring equivalent performance must identify alternative feedthrough capacitors with matching 2 kVDC ratings and 10 nF capacitance. Verify that replacement components maintain similar physical dimensions for bushing mounts and meet the same thermal and current specifications. Cross-reference datasheets to ensure compatible attenuation characteristics for the target application frequency.

Part Context

The SFJEL series represents Knowles Syfer's line of high-voltage feedthrough filters designed for rigorous environments. This specific model belongs to the discontinued product portfolio, indicating it has been superseded by newer generations or phased out due to manufacturing updates. Understanding its historical context aids in selecting modern equivalents with improved reliability metrics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users must consult official Knowles Syfer obsolescence notices or distributor cross-reference tools to identify valid replacements. Ensure any substitute maintains identical voltage, capacitance, and mounting requirements.
