Overview
The Knowles Syfer 1812Y0500563MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in an 1812 package. It features X7R dielectric with a capacitance of 56 nF and a voltage rating of 50 VDC. The component offers ±20% tolerance and operates between -55°C and +125°C. It utilizes FlexiCap technology with a nickel barrier for enhanced reliability.
Feature Summary
- FlexiCap flexible termination design reduces stress on the component during board flexing
- Nickel barrier electrode structure provides improved resistance to cracking
- X7R temperature coefficient ensures stable capacitance across operating range
Applications
- Automotive electronics requiring AEC-Q200 qualification
- Circuit boards susceptible to mechanical flexing
- General purpose decoupling applications
Procurement Notes
Verify the specific suffix MSTE03 against official datasheets to confirm FlexiCap and nickel barrier specifications. Ensure compatibility with automated pick-and-place equipment due to the reel packaging format. Confirm RoHS compliance status through manufacturer documentation prior to integration.
Selection Notes
Select this component when board flex resilience is critical. The 1812 footprint allows higher capacitance density compared to smaller packages. Verify that the 50V rating meets circuit requirements. Consider thermal management within the specified -55°C to +125°C operational window.
Part Context
This part belongs to the Knowles Syfer 1812Y series, designed for high-reliability applications. The series emphasizes durability in harsh environments through specialized termination technologies. It serves as a robust alternative to standard MLCCs in automotive and industrial sectors where mechanical integrity is paramount.
Replacement Considerations
Check for direct substitutes within the same series offering identical FlexiCap characteristics. Verify package dimensions and terminal configurations match existing footprints. Ensure electrical parameters align with circuit design constraints before substitution.
