Overview
The Knowles Syfer 1812Y0500332MJTE03 is a Class 1 multilayer ceramic capacitor (MLCC) in an 1812 surface-mount package. It features a C0G/NP0 dielectric with a capacitance of 3.3 nF, a DC voltage rating of 50 VDC, and a tolerance of ±20%. The component utilizes FlexiCap™ technology with nickel barrier and tin terminations for enhanced mechanical reliability. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- FlexiCap™ flexible termination technology accommodates board bending and thermal cycling stress
- C0G/NP0 dielectric ensures stable capacitance characteristics over temperature variations
- Nickel barrier and tin plating provides reliable solderability and corrosion resistance
Applications
- Automotive electronics requiring AEC-Q200 qualification
- Applications sensitive to board flexing and mechanical stress
- High-reliability circuits demanding stable Class 1 performance
Procurement Notes
Verify the specific suffix codes against official datasheets to confirm termination material and tolerance specifications. Ensure compatibility with assembly processes regarding the FlexiCap™ flexible terminations. Confirm RoHS compliance status through manufacturer documentation before integration into regulated products.
Selection Notes
Select this component when high mechanical reliability under board flexure is required alongside precise Class 1 stability. The FlexiCap™ design offers superior crack resistance compared to standard terminations. Verify that the 1812 footprint and 50V rating align with the target circuit constraints and thermal environment requirements.
Part Context
This part belongs to the Knowles Syfer FlexiCap™ series, designed for applications requiring increased tolerance to mechanical stress. The series is qualified for automotive use under AEC-Q200 standards. It addresses reliability issues in rigid MLCCs by incorporating proprietary flexible termination materials.
Replacement Considerations
Direct substitutes must match the 1812 footprint, 50V rating, 3.3nF capacitance, C0G dielectric, and FlexiCap™ termination type. Verify equivalent AEC-Q200 qualification if used in automotive contexts.
