1812Y5000223MXTE03

Overview

The Knowles Syfer 1812Y5000223MXTE03 is a high-reliability multilayer ceramic capacitor (MLCC) from the FlexiCap series. It features an X7R dielectric with a capacitance of 0.022 µF and a DC voltage rating of 500 VDC. The component utilizes a flexible termination design to withstand board flexing and thermal cycling. It operates within a temperature range of -55°C to +125°C and carries an AEC-Q200 qualification for automotive applications.

Feature Summary

• Flexible Soft Termination technology accommodates significant board bending without cracking
• High reliability construction qualified for space applications and harsh environments
• AEC-Q200 certified for automotive grade performance and durability

Applications

• Automotive electronics requiring board-flex sensitivity tolerance
• Spacecraft electronic systems demanding high mechanical reliability
• High-voltage circuits in industrial equipment subject to thermal cycling

Procurement Notes

Verify the specific suffix MXTE03 indicates the feed-through configuration, as standard FlexiCap parts may differ. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the procurement channel provides traceability documentation required for automotive or aerospace supply chains.

Selection Notes

Select this component when standard MLCCs fail due to mechanical stress during assembly or operation. The flexible termination allows use in rigid PCB layouts where warping occurs. Verify that the 500V rating meets circuit requirements and that the X7R characteristics suit the signal stability needs.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, distinguished by proprietary soft terminations. Unlike standard rigid-termination capacitors, these are engineered to survive extreme mechanical strain. The series includes various voltage ratings and capacitance values optimized for high-reliability sectors.

Replacement Considerations

Standard 1812 X7R capacitors lack the flexible termination and will likely crack under similar mechanical stress. Direct substitutes must match the 500V rating, 0.022 µF value, and specifically feature FlexiCap or equivalent flexible termination technology to ensure mechanical compatibility.
