SFJEL2K00472MX0

Overview

The Knowles Syfer SFJEL2K00472MX0 is a feedthrough capacitor with a capacitance of 4700 pF and a DC voltage rating of 2 kV. It utilizes X7R dielectric material and offers a tolerance of ±20%. Designed for axial mounting, this component operates within a temperature range of -55°C to +125°C. The device functions as an EMI filter, providing signal integrity in high-voltage environments through its robust axial bushing construction.

Feature Summary

• Axial feedthrough configuration for direct cable or panel mounting
• High voltage insulation capability rated at 2 kVDC
• X7R ceramic dielectric for stable performance across wide temperature ranges

Applications

• Electromagnetic interference filtering in high-voltage power lines
• Signal conditioning in aerospace and defense electronic systems
• Industrial equipment requiring robust EMI suppression

Procurement Notes

Verify the specific suffix and marking codes against the manufacturer's latest datasheet to ensure exact electrical compatibility. Confirm that the axial bushing package dimensions match the mechanical constraints of the target assembly. Check for any recent design changes or obsolescence notices from Knowles Syfer before finalizing procurement plans.

Selection Notes

Select this component when a high-voltage feedthrough solution is required for EMI suppression. The 2 kV rating distinguishes it from lower-voltage series like SFSWG. Ensure the application can accommodate the axial form factor and that the X7R temperature characteristics meet the operational thermal requirements.

Part Context

This part belongs to the Knowles Syfer feedthrough capacitor portfolio, specialized for EMI filtering. Unlike surface-mount MLCCs, these components are designed for axial integration into cables or chassis panels. The SFJEL series specifically targets higher voltage applications compared to standard low-voltage feedthrough options.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify mechanical fit and electrical ratings carefully if considering alternative axial feedthrough capacitors from other manufacturers.
