Procurement Notes
Verify part status carefully as this specific suffix variant may be obsolete or discontinued compared to active equivalents like the MX1 version. Confirm thread compatibility and electrical ratings against current design requirements before procurement. Check manufacturer documentation for availability and lead times associated with legacy components.
Selection Notes
Select this component when a 2 kV rated feedthrough capacitor with 2200 pF capacitance is required for panel mounting. Ensure the application environment stays within the specified -55°C to +125°C operating range. Verify that the 1/4-28 UNF thread matches the chassis interface. Consider active alternatives if obsolescence is a concern.
Part Context
This component belongs to the SFJE series of EMI feedthrough filters from Knowles Syfer. These devices are designed to attenuate high-frequency noise on power and signal lines while maintaining structural integrity in harsh environments. The series typically offers various voltage ratings and capacitance values to suit different filtering needs.
Replacement Considerations
Public confirmed substitute: SFJEL2K00222MX1. This variant shares identical electrical specifications including 2 kV rating, 2200 pF capacitance, and 15 A current handling. Verify package and thread compatibility before substitution.
