SFJEL2K00331MC1

Overview

The Knowles Syfer SFJEL2K00331MC1 is a feedthrough capacitor with a capacitance of 330 pF and a voltage rating of 2 kV. It features an axial, bushing package with a diameter of 9.80 mm and length of 9.40 mm. The component utilizes C0G (NP0) dielectric material, offering a tolerance of ±20%. It supports a current rating of 15 A and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high-frequency noise suppression through feedthrough architecture
• Maintains stable electrical characteristics via C0G/NP0 dielectric construction
• Supports high current loads up to 15 A for robust circuit protection

Applications

• High-voltage power supply filtering
• RF signal line noise suppression
• Medical equipment power conditioning

Procurement Notes

Verify the specific suffix MC1 against official datasheets to confirm terminal configuration and sealing type. Ensure the axial bushing dimensions match the panel cutout requirements. Confirm RoHS compliance status for the specific manufacturing batch before integration into regulated assemblies.

Selection Notes

Select this component when high-frequency attenuation is required in high-voltage environments. The C0G dielectric ensures minimal capacitance drift over temperature variations. Verify that the 15 A current rating exceeds the maximum expected load current to prevent thermal failure during operation.

Part Context

This part belongs to the SFJE series of EMI feedthrough filters manufactured by Knowles Syfer. These components are designed for applications requiring effective electromagnetic interference reduction in compact axial packages. The series is commonly used in aerospace, defense, and industrial electronics where reliability under harsh conditions is critical.

Replacement Considerations

Check for direct cross-references from other manufacturers offering identical 330 pF, 2 kV axial feedthrough capacitors. Ensure any substitute matches the 9.80 mm diameter and 1/4-28 thread specification if applicable. Verify that the replacement maintains the same C0G dielectric class and 15 A current handling capability.
