Overview
The Knowles Syfer SFJEL5000223MX0 is an EMI feedthrough filter capacitor from the SFJE series. It features a capacitance of 0.022 µF (22 nF) with a ±20% tolerance and a rated voltage of 500 VDC. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range of -55°C to +125°C. Designed for panel mounting, it incorporates a threaded connection interface. The unit is currently classified as obsolete by the manufacturer.
Feature Summary
- Provides electromagnetic interference suppression through axial feedthrough architecture
- Utilizes robust X7R ceramic dielectric for thermal stability
- Features threaded mechanical interface for secure panel integration
Applications
- Electromagnetic interference filtering in electronic enclosures
- Power line conditioning within industrial control systems
- Signal integrity protection in sensitive instrumentation panels
Procurement Notes
This component is officially listed as obsolete by Knowles Syfer. Availability is restricted to existing stock or secondary market channels. Verify manufacturing date codes and physical condition carefully. Confirm compatibility with replacement components before finalizing procurement decisions due to discontinued status.
Selection Notes
Select this part only if legacy system compatibility requires the specific SFJE series form factor and electrical characteristics. Evaluate alternative current production feedthrough capacitors from the same manufacturer family that match the required capacitance, voltage rating, and mounting thread specifications to ensure long-term supply chain stability.
Part Context
The SFJEL5000223MX0 belongs to the SFJE series of feedthrough capacitors manufactured by Knowles Syfer. This series is designed for high-reliability applications requiring effective noise attenuation. The component represents a specialized passive filter solution intended for direct panel mounting rather than standard printed circuit board assembly.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official manufacturer catalogs for equivalent active components matching the 500V rating, 0.022µF capacitance, and M5 thread specification.
