Overview
The Knowles Syfer 1812Y0500272MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in the FlexiCap series. It features an X7R dielectric with a capacitance of 2700 pF and a DC voltage rating of 50 VDC. The component offers a tolerance of ±20% and operates within a temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it utilizes a nickel barrier electrode structure. This part is AEC-Q200 qualified for automotive applications.
Feature Summary
- FlexiCap technology provides flexible terminations to enhance resistance against board flex-induced cracking.
- Nickel barrier internal electrodes ensure reliability in high-reliability environments.
- AEC-Q200 qualification confirms suitability for demanding automotive electronic applications.
Applications
- Automotive electronics requiring board-flex sensitivity mitigation
- High-reliability surface mount circuits
- General purpose decoupling in automotive-grade systems
Procurement Notes
Verify the complete part number including the suffix MSTE03 to confirm the specific termination and packaging configuration. Ensure compatibility with the target PCB's mechanical stress profile due to the FlexiCap design. Confirm RoHS compliance status through official manufacturer documentation prior to integration.
Selection Notes
Select this component when board flex resilience is critical in automotive or industrial designs. The X7R dielectric provides stable performance across the specified temperature range. Consider the 1812 footprint constraints and the 50V rating relative to circuit requirements.
Part Context
This part belongs to the Knowles Syfer 1812Y series, which specializes in high-reliability MLCCs. The series integrates FlexiCap technology to address mechanical failure modes common in rigid ceramic capacitors during assembly or operation on flexible substrates.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify cross-reference data directly from the manufacturer before substitution.
