SFJEC2K00681MC0

Overview

The SFJEC2K00681MC0 is an EMI feedthrough capacitor from the Knowles Syfer SFJE series. It features a capacitance of 680 pF with a tolerance of ±20%. The component has a DC voltage rating of 2 kVDC and supports a maximum DC current of 15 A. It utilizes C0G (NP0) dielectric material for stable performance across a temperature range of -55°C to +125°C. The package is axial with a bushing mount style, measuring 9.4 mm in length and 9.8 mm in diameter.

Feature Summary

• Provides electromagnetic interference suppression through high-current feedthrough filtering
• Features a robust bushing mounting style for secure panel installation
• Utilizes C0G dielectric for consistent capacitance stability over wide temperature variations

Applications

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

Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm mechanical dimensions and termination details. Ensure the selected variant matches the required bushing thread size and current handling capabilities for the target application environment.

Selection Notes

Select this component when high current capacity and high voltage isolation are required in a single feedthrough structure. The C0G dielectric ensures minimal capacitance drift under varying thermal conditions compared to other ceramic types.

Part Context

This part belongs to the SFJE series of feedthrough capacitors designed for harsh environments. It integrates filtering and insulation functions into a compact axial bushing package, suitable for applications requiring reliable EMI reduction without additional discrete components.

Replacement Considerations

Consult the manufacturer's cross-reference guide for direct replacements. Verify that any substitute maintains the same 2 kVDC rating, 15 A current capacity, and compatible physical mounting dimensions.
