SFSWR5000332MX0

Overview

The Knowles Syfer SFSWR5000332MX0 is a hermetic feedthrough capacitor designed for EMI filtering applications. It features a capacitance of 3.3 nF with a tolerance of ±20%. The component is rated for a DC voltage of 500 VDC and supports a continuous current rating of 5 A. Constructed with X7R dielectric material, it operates within a temperature range of -55°C to +125°C. The physical dimensions are 3.29 mm in length and 3.25 mm in diameter. It utilizes solder termination and employs a bottom end seal configuration.

Feature Summary

• Hermetic bottom end seal construction ensures environmental protection and reliability.
• X7R dielectric material provides stable capacitance characteristics across the operating temperature range.
• Solder mount termination facilitates integration into printed circuit board assemblies.

Applications

• Electromagnetic interference (EMI) filtering in electronic circuits
• Power supply input/output stages requiring high-voltage isolation
• Military and aerospace systems demanding hermetic sealing

Procurement Notes

Verify the specific suffix MX0 against official datasheets to confirm the bottom end seal configuration and bulk packaging details. Ensure compatibility with the required 500V DC rating and 5A current handling capacity for the target application environment. Cross-reference the X7R dielectric specification to validate thermal stability requirements.

Selection Notes

Select this component when a hermetic feedthrough solution is required for high-frequency noise suppression. The bottom end seal design distinguishes it from flange-mounted alternatives. Consider the 3.3 nF value and 500V rating to ensure adequate performance for the specific circuit impedance and voltage levels involved.

Part Context

This part belongs to the SFSWR series of feedthrough capacitors manufactured by Knowles Syfer. The series offers various capacitance values and voltage ratings, all sharing similar hermetic construction methods. The SFSWR designation specifically indicates the bottom end seal variant within the broader product family.

Replacement Considerations

Direct substitutes include other SFSWR series parts with identical electrical parameters but different capacitance values. Flange-mounted equivalents like the SFSWG series may require mechanical adaptation due to differing seal configurations.
