SFJEC2K00682MX1

Overview

The Knowles Syfer SFJEC2K00682MX1 is a high-voltage multilayer ceramic capacitor (MLCC) designed for demanding industrial and power electronics applications. It features a capacitance of 6800 pF with a tolerance of ±20% and a rated DC voltage of 2000 V. The component utilizes X7R dielectric material, providing stable performance across a wide temperature range from -55°C to +125°C. Housed in a robust 2220 (5650 Metric) surface-mount package, it offers high reliability and mechanical strength suitable for harsh environments.

Feature Summary

• High voltage capability up to 2000 V DC for power circuit isolation
• X7R dielectric ensures stable capacitance over extended temperature ranges
• Robust 2220 surface-mount package for enhanced mechanical durability

Applications

• Industrial motor drives and inverters
• High-voltage power supply filtering
• Medical imaging equipment power stages

Procurement Notes

Verify the complete part number including suffixes against official Knowles Syfer documentation to ensure correct voltage rating, termination finish, and packaging configuration. Confirm RoHS compliance status and specific reel quantities if ordering in tape-and-reel format. Cross-reference manufacturer datasheets for storage and soldering recommendations to maintain component integrity.

Selection Notes

Select this component when high voltage isolation and compact footprint are required in surface-mount designs. Ensure the operating voltage remains below the 2000 V DC rating with appropriate derating factors. Consider the X7R temperature coefficient for circuits requiring moderate stability under thermal variation. Verify PCB land pattern compatibility with the 2220 package dimensions.

Part Context

This MLCC belongs to the Knowles Syfer SFJE series, engineered for high-voltage industrial applications. The series emphasizes reliability in power conversion systems where space constraints and electrical stress are critical design factors. Components in this line typically feature specialized electrode structures to withstand high electric fields without breakdown.

Replacement Considerations

Consult official substitution guides for equivalent high-voltage MLCCs with matching 2000 V ratings and 2220 footprints. Verify that alternative parts meet the same X7R temperature characteristics and physical dimensions. Ensure any substitute maintains comparable surge current handling capabilities.
