Overview
The Knowles Syfer 0805Y0500821MXTE01 is a surface-mount multilayer ceramic capacitor (MLCC) designed for board-flex sensitive applications. It features an X7R dielectric with a capacitance of 820 pF and a DC voltage rating of 50 VDC. The component utilizes the FlexiCap™ technology, incorporating flexible nickel barrier terminations to enhance mechanical reliability under stress. It operates within a temperature range of -55°C to +125°C and is housed in a standard 0805 (2012 metric) package.
Feature Summary
- FlexiCap™ flexible termination technology reduces stress on internal electrodes during board flexing
- Nickel barrier construction provides enhanced durability and solderability
- X7R dielectric ensures stable capacitance performance across a wide operating temperature range
Applications
- Board-flex sensitive electronic assemblies
- Automotive electronics requiring AEC-Q200 qualification
- High-reliability industrial equipment
Procurement Notes
Verify the specific suffix E01 against official documentation to confirm the exact termination configuration and packaging details. Ensure compatibility with PCB designs requiring flexible terminations. Confirm RoHS compliance status through the manufacturer's current environmental declarations before final procurement integration.
Selection Notes
Select this component when mechanical robustness against substrate warpage or vibration is critical. The FlexiCap™ design addresses common failure modes associated with rigid terminations in high-stress environments. Verify that the 50V rating and 820pF value align with circuit requirements without necessitating higher voltage derating.
Part Context
This part belongs to the Knowles Syfer FlexiCap™ series, which specializes in capacitors engineered for mechanical resilience. The 0805Y prefix indicates the 0805 footprint and 50V class. This series is widely utilized in automotive and industrial sectors where standard MLCCs may fail due to mechanical strain.
Replacement Considerations
Direct substitutes include other FlexiCap™ variants such as 0805Y0500821MXT if packaging differences are acceptable. Cross-reference termination materials and tolerance specifications to ensure functional equivalence in board-flex applications.
