SFJEL1K00333MX0

Overview

The Knowles Syfer SFJEL1K00333MX0 is a feedthrough capacitor from the SFJE series, designed for electromagnetic interference suppression. It features an axial bushing configuration with silver-plated terminals. The component has a capacitance of 0.033 µF and a DC voltage rating of 1000 V. It supports a continuous current of 15 A and operates within a temperature range of -55 °C to +125 °C. The physical dimensions are 9.80 mm in diameter and 9.40 mm in length.

Feature Summary

• Provides effective electromagnetic interference filtering through axial bushing construction
• Capable of handling high continuous current loads up to 15 amperes
• Rated for high DC voltage applications at 1000 volts

Applications

• Power supply input filtering
• High-voltage electronic equipment noise suppression
• Industrial control system EMI mitigation

Procurement Notes

Verify the specific suffix MX0 against official datasheets to confirm terminal finish and packaging details. Ensure the 1000V rating and 15A current capacity align with circuit requirements. Confirm compatibility with panel mounting holes given the 9.80mm diameter specification. Cross-reference the 0.033µF capacitance value with design schematics to prevent mismatched filtering characteristics.

Selection Notes

Select this component when high voltage isolation and significant current carrying capability are required in a compact axial form factor. The 1000V rating distinguishes it from lower voltage variants in the SFJE family. Consider the 9.80mm diameter for panel cutout constraints. The silver plating offers reliable solderability and corrosion resistance for long-term industrial deployments.

Part Context

This part belongs to the Knowles Syfer SFJE series of feedthrough capacitors. These components utilize ceramic dielectric technology for stable performance across wide temperature ranges. The series is engineered for robust EMI suppression in demanding environments where standard surface mount or through-hole capacitors may fail under high voltage stress.

Replacement Considerations

Direct substitutes include other SFJE series parts with matching 1000V ratings and similar capacitance values. Verify that alternative feedthrough capacitors maintain the same 15A current rating and axial bushing footprint to ensure mechanical fit without panel modification.
