SFJEC5000473MX0

Overview

The Knowles Syfer SFJEC5000473MX0 is an electromagnetic interference (EMI) feedthrough capacitor designed for axial lead mounting. It features a capacitance of 47 nF with a tolerance of ±20% and a DC voltage rating of 500 VDC. The component utilizes X7R dielectric material, ensuring stable performance across a wide operating temperature range from -55°C to +125°C. It supports a maximum DC current of 10 A and is housed in a bulk package configuration.

Feature Summary

• Provides effective EMI suppression through dedicated feedthrough filter architecture
• Supports high current handling capabilities suitable for power line applications
• Maintains electrical stability under extreme thermal conditions using X7R dielectric

Applications

• Power supply input filtering
• Industrial control system noise reduction
• Medical equipment signal integrity protection

Procurement Notes

Verify the specific axial lead configuration and terminal plating requirements against your assembly specifications. Confirm that the 500 VDC rating and 10 A current capacity align with your circuit design parameters. Ensure compatibility with your existing PCB or panel mounting infrastructure before finalizing procurement decisions.

Selection Notes

Select this component when axial lead termination is required for robust mechanical connection in high-voltage environments. The 47 nF value offers a balance between low-frequency attenuation and physical size constraints. Consider the X7R temperature coefficient if the application involves significant thermal fluctuations during operation.
