Procurement Notes
Verify the specific suffix MX0 against official datasheets to confirm terminal configuration and sealing type. Ensure the 500V DC rating and 5A current capacity align with circuit requirements. Confirm RoHS compliance status through manufacturer documentation before integration.
Selection Notes
Select this component when a compact, high-voltage feedthrough solution is required for noise reduction. The 10 nF value suits general-purpose filtering. Verify that the 3.25 mm diameter fits the panel or chassis aperture constraints. Ensure the operating environment remains within the specified -55 C to +125 C range for optimal reliability.
Part Context
This part belongs to the SFSWR series of feedthrough capacitors from Knowles Syfer. The series offers various capacitance values and voltage ratings for EMI suppression. These components are categorized as single-terminal filters designed for direct board or panel mounting.
Replacement Considerations
Consult official substitution guides for equivalent SFSWR variants with matching capacitance and voltage ratings. Cross-reference physical dimensions to ensure mechanical compatibility.
