1812Y0500332MSTE03

Overview

The Knowles Syfer 1812Y0500332MSTE03 is a multilayer ceramic capacitor (MLCC) in the FlexiCap series. It features an X7R dielectric with a capacitance of 3300 pF and a tolerance of ±20%. Rated for 50 VDC, it utilizes flexible terminations to withstand board bending and thermal cycling from -55°C to +125°C. The component meets AEC-Q200 standards and incorporates an X2Y architecture for enhanced noise suppression.

Feature Summary

• Flexible termination technology accommodates significant PCB bending without cracking
• X2Y architecture provides integrated common-mode noise filtering
• AEC-Q200 qualified for automotive reliability requirements

Applications

• Automotive electronic systems requiring high mechanical reliability
• Noise suppression circuits utilizing X2Y topology
• Applications subject to severe thermal cycling environments

Procurement Notes

Verify the specific suffix MSTE03 against official datasheets to confirm the X2Y configuration and AEC-Q200 qualification status. Ensure the flexible termination specifications align with the target PCB assembly stress profiles. Cross-reference the manufacturer's latest documentation to validate compliance details before finalizing procurement.

Selection Notes

Select this component when standard MLCCs fail under mechanical stress or when integrated noise filtering is required. The X2Y design reduces component count by combining capacitance and filtering functions. Verify that the 50V rating and X7R temperature characteristics meet the circuit's operational voltage and environmental constraints.
