Overview
The SFJNC5000104MX0 is an EMI feedthrough filter manufactured by Knowles Syfer. It features a C-filter circuit topology with a capacitance of 0.1 uF (100 nF) and a voltage rating of 500 VDC. The component utilizes X7R dielectric material with a 20% tolerance. It supports a maximum DC current of 10 A and operates within a temperature range of -55°C to +125°C. The package is threaded panel mount with M6 x 0.75 thread size, measuring 9.4 mm in length and 9.8 mm in diameter.
Feature Summary
- Provides electromagnetic interference suppression through axial feedthrough capacitor design
- Enables secure installation via threaded panel mount configuration
- Maintains stable electrical performance across wide industrial temperature ranges
Applications
- Power supply input filtering for electronic equipment
- Signal line noise reduction in control systems
- EMI mitigation in aerospace and defense electronics
Procurement Notes
Verify the exact capacitance value against official datasheets, as similar part numbers may differ significantly. Confirm thread specifications and mounting requirements match the application panel. Check RoHS compliance status and lead-free certification if required by project standards. Ensure the voltage rating meets or exceeds the system operating conditions.
Selection Notes
Select this component when high-current handling and robust mechanical mounting are required. The threaded design offers superior grounding compared to solder-only variants. Consider the physical dimensions for panel cutout compatibility. Evaluate the thermal stability provided by the X7R dielectric for the specific operating environment.
Part Context
This part belongs to the SFJN series of EMI feedthrough filters from Knowles Syfer. These components are designed for high-reliability applications requiring effective noise filtration. The series typically includes various capacitance values and voltage ratings to suit different circuit requirements.
Replacement Considerations
SFJNC5000103MX0 is a related variant with 10 nF capacitance. Verify that the lower capacitance value meets the filtering requirements before substitution.
