SFJEL3000474MX1

Overview

The Knowles Syfer SFJEL3000474MX1 is an axial feedthrough capacitor designed for electromagnetic interference (EMI) filtering. It features a capacitance of 0.47 µF with a voltage rating of 300 VDC. The component utilizes an axial bushing package configuration, enabling direct mounting onto panel holes or chassis openings. This design facilitates efficient grounding and signal path separation in high-noise environments.

Feature Summary

• Axial bushing package allows direct panel mounting for secure mechanical attachment
• Feedthrough architecture provides effective EMI suppression by separating input and output paths
• Capacitive filtering action attenuates high-frequency noise across the conductive axis

Applications

• Panel-mounted EMI filters for electronic enclosures
• Chassis penetration points for signal and power lines
• High-noise industrial equipment filtering applications

Procurement Notes

Verify the specific voltage rating and capacitance tolerance against system requirements before integration. Confirm that the axial bushing dimensions match the available panel cutouts. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the manufacturer's datasheet for precise mechanical drawings and mounting torque specifications to guarantee reliable performance.

Selection Notes

Select this component when a robust, panel-mountable filter is required for significant noise attenuation. The axial bushing style offers superior mechanical stability compared to surface-mount alternatives in vibration-prone settings. Consider the 300 VDC rating and 0.47 µF capacitance value to ensure compatibility with the circuit's electrical parameters and noise spectrum characteristics.

Part Context

This part belongs to the Knowles Syfer feedthrough capacitor family, which specializes in high-reliability EMI filtering solutions. These components are engineered for demanding applications where space constraints and noise immunity are critical. The axial bushing design distinguishes it from flange-sealed or three-terminal variants, offering a unique mounting topology for panel integration.
