SFJEL2K00332MX0

Overview

The Knowles Syfer SFJEL2K00332MX0 is an axial feedthrough capacitor designed for high-voltage EMI filtering applications. It features a capacitance of 3300 pF with a DC voltage rating of 2 kVDC. The component utilizes C0G dielectric material, ensuring stable performance across its operating temperature range of -55°C to +125°C. It has a tolerance of ±20% and is housed in an axial bushing package suitable for panel mounting.

Feature Summary

• Provides effective electromagnetic interference (EMI) filtering through feedthrough architecture
• Utilizes C0G dielectric for consistent capacitance stability over temperature variations
• Features axial bushing construction for secure panel or chassis mounting

Applications

• High-voltage power supply input filtering
• Industrial control system EMI suppression
• Medical equipment signal line protection

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Knowles Syfer before procurement. Confirm that the axial bushing dimensions match the mechanical constraints of the target enclosure. Ensure the 2 kVDC rating exceeds the maximum circuit voltage including transients. Check for any specific handling requirements due to the ceramic construction.

Selection Notes

Select this component when board-mounted MLCCs cannot provide sufficient isolation or when panel-mount filtering is required. The axial form factor allows direct integration into cable assemblies or chassis holes. Consider the physical size of the bushing against available panel space. Verify that the current rating meets the application's load requirements without excessive heating.

Part Context

This part belongs to the Knowles Syfer SFJEL series of feedthrough capacitors. These components are engineered for environments requiring robust noise suppression where traditional surface-mount devices may fail due to voltage stress or mechanical vibration. The series offers various capacitance and voltage ratings to suit different filtering needs.

Replacement Considerations

Direct substitutes must match the 3300 pF capacitance, 2 kVDC rating, and axial bushing package. Verify that alternative feedthrough capacitors maintain similar C0G dielectric characteristics and physical mounting hole dimensions to ensure compatibility with existing PCB or panel layouts.
