Overview
The Knowles Syfer SFSWR2000223MX0 is a feedthrough capacitor designed for electromagnetic interference (EMI) filtering. It features a capacitance of 22 nF with a tolerance of ±20%. The component has a DC voltage rating of 200 VDC and utilizes an X7R dielectric material. It is housed in a cylindrical package with dimensions of 3.29 mm in length and 3.25 mm in diameter. The device supports a current rating of 5 A and operates within a temperature range of -55°C to +125°C. It employs solder termination and offers an insulation resistance of 10 GOhms.
Feature Summary
- Provides effective EMI suppression through feedthrough capacitor architecture
- Utilizes X7R ceramic dielectric for stable performance across operating temperatures
- Features bottom end seal construction for secure mounting
Applications
- Electromagnetic interference filtering in electronic circuits
- Power supply line conditioning
- Signal integrity protection in sensitive equipment
Procurement Notes
Verify the specific suffix MX0 against official manufacturer documentation to confirm exact packaging and terminal specifications. Ensure compatibility with existing board layouts regarding the 3.29 mm length and 3.25 mm diameter footprint. Confirm that the 200 VDC rating and 5 A current handling meet the system requirements before integration.
Selection Notes
Select this component when a compact feedthrough solution is required for 200 VDC applications. The 22 nF capacitance value suits general EMI filtering needs. Consider the X7R dielectric characteristics for temperature stability. Verify that the bottom end seal configuration aligns with the mechanical assembly constraints of the target design.
Part Context
This part belongs to the SFSWR series of feedthrough capacitors from Knowles Syfer. The series is characterized by cylindrical packages and solder terminations. These components are categorized as EMI filters and are distinct from standard multilayer ceramic capacitors due to their specialized feedthrough structure.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult official manufacturer cross-reference lists for verified alternatives.
