SFJEL3000474MX0

Overview

The Knowles Syfer SFJEL3000474MX0 is an axial lead EMI feedthrough capacitor designed for high-performance noise suppression. It features a capacitance of 0.47 µF with a tolerance of ±20%. The component is rated for a maximum DC voltage of 300 VDC and can handle a continuous current of up to 10 A. Constructed with X7R dielectric material, it operates reliably within a temperature range of -55°C to +125°C. The unit utilizes a flange end seal construction to ensure environmental protection and mechanical stability in demanding applications.

Feature Summary

• Flange end seal construction provides robust environmental sealing and mechanical integrity
• Axial lead configuration facilitates straightforward integration into existing wiring harnesses
• X7R ceramic dielectric ensures stable capacitance performance across the specified operating temperature range

Applications

• Electromagnetic interference filtering in industrial control systems
• Noise suppression in aerospace and defense electronic assemblies
• Power supply input/output filtering in medical equipment
• Signal conditioning in automotive electronics

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact electrical tolerances and termination specifications. Ensure that the selected variant matches the required voltage rating and current handling capabilities for the target application environment. Cross-reference the package dimensions with the design layout to guarantee proper fitment within the enclosure constraints.

Selection Notes

Select this component when high current handling and moderate capacitance are required in an axial form factor. The 300 VDC rating suits applications with significant DC bias voltages. Consider the thermal management requirements given the 10 A current capacity and the operational temperature limits defined by the X7R dielectric characteristics.

Part Context

This part belongs to the SFJEL series of feedthrough capacitors from Knowles Syfer. The series is engineered for high-reliability environments where compact size and effective EMI attenuation are critical. These components typically replace traditional discrete filter networks with a single, integrated solution that simplifies PCB or panel mounting processes.

Replacement Considerations

Consult the official Knowles Syfer substitution guide for verified equivalents. Direct replacements must match the 0.47 µF capacitance, 300 VDC rating, and axial flange-end seal physical dimensions to maintain circuit integrity.
