SFCMC0500334MX0

Overview

The Knowles Syfer SFCMC0500334MX0 is an EMI feedthrough filter capacitor designed for surface-mount applications. It features a capacitance of 0.33 µF with a ±20% tolerance and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material, ensuring stable performance across a wide temperature range from -55°C to +125°C. Packaged in a compact 1812 (4532 metric) case size, it employs flexible SMD/SMT terminations to enhance mechanical reliability during soldering and thermal cycling.

Feature Summary

• Integrated EMI filtering capability within a compact surface-mount footprint
• Flexible termination design for improved mechanical stress resistance
• X7R dielectric construction for consistent electrical characteristics over temperature variations

Applications

• High-density PCB layouts requiring integrated EMI suppression
• Power supply input/output filtering stages
• Signal line protection in sensitive electronic circuits

Procurement Notes

Verify the exact suffix configuration against official manufacturer documentation to ensure correct termination and packaging specifications. Confirm RoHS compliance status and environmental declarations prior to integration. Cross-reference the full part number with authorized distributor catalogs to validate current availability and lead times for production planning.

Selection Notes

Select this component when space constraints necessitate a small 1812 footprint combined with significant capacitance values. Ensure the operating environment remains within the specified -55°C to +125°C range to maintain X7R dielectric stability. Evaluate the 50V DC rating against peak transient voltages to prevent breakdown. Consider the flexible termination benefits if board flex or thermal shock resistance is critical.

Part Context

This component belongs to the Knowles Syfer EMI feedthrough filter series, which specializes in combining filtering functions with standard passive footprints. These devices are engineered to replace traditional discrete components by integrating capacitance directly into the mounting structure, thereby reducing board space and simplifying assembly processes for modern electronics.

Replacement Considerations

Consult official substitution guides for compatible alternatives within the same series. Verify that any substitute matches the 1812 dimensions, 50V rating, and 0.33µF capacitance while maintaining compatible termination styles.
