SFAAC1000223MX0

Overview

The Knowles Syfer SFAAC1000223MX0 is an EMI feedthrough filter capacitor designed for surface-mount applications. It features a capacitance of 0.022 µF with a tolerance of ±20%, utilizing X7R dielectric material. The component is rated for a DC voltage of 100 V and operates within a temperature range of -55 °C to +125 °C. It employs a flange end seal construction with a 4-40 UNC thread size, ensuring secure mechanical mounting and effective electromagnetic interference suppression in compact electronic assemblies.

Feature Summary

• Flange end seal construction provides robust mechanical stability and reliable grounding for high-frequency noise attenuation.
• X7R dielectric material ensures stable capacitance performance across the specified operating temperature range.
• Integrated 4-40 UNC threaded interface facilitates direct panel or chassis mounting without additional hardware.

Applications

• Electromagnetic interference (EMI) filtering in sensitive communication equipment
• Power supply input/output stages requiring high-frequency noise suppression
• Automotive electronics systems demanding reliable component mounting
• Industrial control panels needing robust ground reference connections

Procurement Notes

Verify the specific package variant and manufacturing date code against project requirements before ordering. Confirm that the 4-40 UNC thread specification aligns with the intended mounting infrastructure. Ensure the X7R dielectric characteristics meet the thermal and electrical demands of the target application environment. Cross-reference the datasheet for any recent design changes or compliance updates prior to final procurement decisions.

Selection Notes

Select this component when a surface-mount EMI filter requires a fixed mechanical anchor point via threading. The 100 VDC rating and 0.022 µF value suit general-purpose noise suppression tasks. Consider the ±20% tolerance if precise capacitance tuning is not critical. Evaluate the physical dimensions and thread engagement depth to ensure compatibility with the host board or panel layout constraints.

Part Context

This part belongs to the Knowles Syfer SFAA series of EMI feedthrough filters. These components are engineered for high-reliability applications where both electrical filtering performance and mechanical integrity are paramount. The series offers various capacitance values and voltage ratings to accommodate diverse circuit protection needs while maintaining consistent form factors for standardized mounting solutions.

Replacement Considerations

No public confirmed substitute part numbers are available for this specific model. Direct replacement requires matching the 4-40 UNC thread, 100 VDC rating, 0.022 µF capacitance, and X7R dielectric type. Verify dimensional compatibility and thermal specifications before considering alternative suppliers or generic equivalents.
