SFJEC1K00333MX1

Overview

The SFJEC1K00333MX1 is a Knowles Syfer EMI feedthrough filter from the SFJE series. It features a capacitance of 0.033 µF with a voltage rating of 1000 V (1 kV). The component supports a maximum DC current of 15 A and utilizes an axial bushing configuration for panel mounting.

Feature Summary

• Provides electromagnetic interference suppression via feedthrough filtering architecture
• Engineered for high-voltage direct current circuit protection
• Designed for secure threaded panel mounting applications

Applications

• High-voltage power supply input filtering
• Industrial control system signal conditioning
• Medical equipment power interface protection

Procurement Notes

Verify the specific datasheet version for the SFJEC1K00333MX1 to confirm mechanical dimensions and terminal specifications. Ensure the mounting hole diameter matches the bushing requirements. Confirm insulation resistance ratings align with the target application environment before finalizing procurement.

Selection Notes

Select this component when high-voltage isolation and low-pass filtering are required in a single package. The 15 A current rating suits moderate power applications. Verify that the axial bushing form factor fits the available panel space compared to flange-mounted alternatives.

Part Context

This part belongs to the Knowles Syfer SFJE series of ceramic feedthrough capacitors. These components are designed to replace traditional discrete LC filters by integrating capacitance and grounding into a single hermetically sealed unit, reducing board space and improving high-frequency performance.

Replacement Considerations
