SFJNL3000474MX0

Overview

The SFJNL3000474MX0 is an EMI feedthrough filter manufactured by Knowles Syfer, belonging to the SFJN series. It functions as a C-filter with a capacitance of 47 nF and a voltage rating of 500 VDC. The component utilizes X7R dielectric material and offers a tolerance of 20%. It supports a maximum DC current of 10 A and operates within a temperature range of -55°C to +125°C. Physical dimensions include a diameter of 6.35 mm, a length of 11.8 mm, and a lead diameter of 0.7 mm. The unit features M6 x 0.75 threading and is supplied in bulk packaging.

Feature Summary

• Provides electromagnetic interference suppression through axial feedthrough capacitor design
• Utilizes X7R dielectric for stable performance across specified temperature ranges
• Features threaded mounting interface for secure panel installation

Applications

• Power supply filtering
• Voltage regulation circuits
• Battery charger systems

Procurement Notes

Verify the specific datasheet version for the SFJNL3000474MX0 to confirm exact mechanical tolerances and electrical characteristics prior to integration. Ensure that the M6 x 0.75 threading requirements align with the target chassis or panel design. Cross-reference the 500 VDC rating and 10 A current capacity against the actual circuit load conditions to prevent derating issues during operation.

Selection Notes

Select this component when high-current DC line filtering is required in compact spaces. The 500 VDC rating distinguishes it from lower-voltage variants within the same series. Consider the physical size constraints relative to the 6.35 mm diameter and 11.8 mm length. Verify compatibility with the operating temperature environment, as the X7R dielectric defines the thermal stability limits of the capacitance value.

Part Context

This part belongs to the Knowles Syfer SFJN series of EMI feedthrough filters. These components are designed for direct wire-to-panel or wire-to-wire connections. The series typically includes various capacitance values and voltage ratings to suit different power electronics applications. The SFJNL3000474MX0 represents a specific configuration within this family, optimized for 500 VDC applications.

Replacement Considerations

Check for other SFJN series parts with similar capacitance and voltage ratings. Verify that any substitute maintains the M6 x 0.75 thread size and compatible physical footprint. Ensure the replacement component meets the same X7R dielectric and temperature specifications.
