SFJNL2K00682MX1

Overview

The SFJNL2K00682MX1 is an EMI feedthrough capacitor manufactured by Knowles Syfer, belonging to the SFJN series. It features a capacitance of 6800 pF with a tolerance of ±20% and a DC voltage rating of 2 kVDC. The component utilizes X7R dielectric material and supports a maximum DC current of 5 A. Designed for axial mounting via a bushing package, it operates within a temperature range of -55°C to +125°C. Key physical dimensions include a diameter of 9.8 mm and a length of 9.4 mm, with M6 x 0.75 threading.

Feature Summary

• Provides electromagnetic interference suppression through high-voltage feedthrough filtering capabilities
• Features robust axial construction with integrated bushing for secure panel or chassis mounting
• Utilizes stable X7R ceramic dielectric to maintain performance across wide industrial temperature ranges

Applications

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

Procurement Notes

Verify the specific suffix MX1 against official datasheets to confirm terminal configuration and sealing type. Ensure compatibility with M6 x 0.75 mounting threads during mechanical integration. Confirm RoHS compliance status directly from the manufacturer's documentation before procurement. Cross-reference the 2 kVDC rating with actual circuit operating conditions to ensure adequate safety margins.

Selection Notes

Select this component when high-voltage isolation and compact axial form factors are required. The 2 kVDC rating suits applications exceeding standard low-voltage filter limits. Consider the 5 A current capacity for moderate power lines. The X7R dielectric offers a balance of capacitance stability and cost-effectiveness compared to C0G types, suitable for general-purpose EMI reduction in harsh environments.
