Overview
The SFJNC1000105MX1 is an electromagnetic interference (EMI) feedthrough filter manufactured by Knowles Syfer. It features a C-filter circuit topology with a capacitance of 1 uF and a voltage rating of 100 VDC. The component utilizes X7R dielectric material with a tolerance of 20%. Designed for threaded panel mount installation, it includes M6 threading. The device supports a maximum DC current of 15 A and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides EMI suppression through integrated feedthrough capacitor design
- Enables secure mechanical attachment via threaded panel mount configuration
- Maintains stable electrical performance across wide industrial temperature ranges
Applications
- Power supply input filtering in electronic equipment
- Signal line noise reduction in control panels
- Electromagnetic compatibility enhancement in industrial machinery
Procurement Notes
Verify the specific suffix MX1 against official datasheets to confirm exact termination and sealing characteristics. Confirm that the M6 thread size matches the mounting aperture requirements. Ensure the 15 A current rating aligns with the operational load. Validate compliance with relevant environmental directives before integration into final assemblies.
Selection Notes
Select this component when high capacitance is required for low-frequency noise attenuation in power lines. The threaded mounting style offers superior mechanical stability compared to solder-only variants. Consider the physical dimensions and thermal limits to ensure compatibility with the enclosure design and operating environment constraints.
Part Context
This part belongs to the SFJN series of EMI feedthrough filters from Knowles Syfer. These components are designed to replace traditional discrete capacitor installations by integrating the filtering element directly into the mounting hardware. The series provides robust shielding and reliable performance in demanding environments.
Replacement Considerations
Direct substitutes include SFJNC1000155MX1 for higher capacitance or SFJNC1000104MX1 for lower capacitance values within the same series. Verify thread compatibility and current ratings when considering alternative models.
