SFJEC2K00103MX1

Overview

The Knowles Syfer SFJEC2K00103MX1 is a feedthrough capacitor designed for electromagnetic interference (EMI) filtering. It features a capacitance of 10,000 pF with a ±20% tolerance and an X7R dielectric material. The component supports a maximum DC voltage rating of 2 kV and handles a maximum DC current of 15 A. It utilizes an axial bushing package configuration suitable for panel mounting. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides EMI suppression through high-voltage feedthrough capacitor architecture
• Utilizes axial bushing design for secure panel mounting integration
• Maintains stable electrical performance across wide industrial temperature ranges

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for the SFJEC2K00103MX1 before procurement, as some distributor listings indicate this part number may be obsolete or superseded by newer revisions. Confirm mechanical dimensions and terminal compatibility with your panel cutout requirements. Ensure the 2 kV rating aligns with your system's peak voltage stresses. Cross-reference the manufacturer's official documentation for any recent lifecycle changes or recommended alternative part numbers.

Selection Notes

Select this component when a robust, high-current feedthrough solution is required for 2 kV systems. The 10 nF capacitance offers effective noise attenuation for mid-frequency interference. Consider the physical size of the axial bushing mount during PCB or chassis layout planning. Verify that the 15 A current handling capability meets the load requirements without excessive thermal rise.

Part Context

This component belongs to the SFJE series of EMI feedthrough filters from Knowles Syfer. These parts are engineered for demanding environments requiring reliable noise suppression in high-voltage applications. The series typically includes various capacitance values and voltage ratings to suit different circuit protection needs.

Replacement Considerations

Check if the SFBDT5000103MX1 is a viable alternative if lower voltage (500 V) and higher current (10 A) specifications are acceptable. Verify mechanical fitment differences between the axial bushing style and threaded panel mount options.
