Overview
The Knowles Syfer 1812Y1000273MSTE03 is a multilayer ceramic capacitor (MLCC) in an 1812 surface-mount package. It features a capacitance of 27 nF with a ±20% tolerance and a DC voltage rating of 100 VDC. The component utilizes X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. It incorporates FlexiCap technology with nickel barrier end terminations for enhanced mechanical reliability. The device is AEC-Q200 qualified and supplied in reel packaging.
Feature Summary
- FlexiCap soft termination design reduces stress on the ceramic body during board flexing
- AEC-Q200 qualification ensures suitability for automotive electronic applications
- X7R dielectric provides reliable capacitance stability over wide operating temperatures
Applications
- Automotive electronics requiring high reliability under mechanical stress
- Circuit boards susceptible to flex-induced cracking
- General-purpose decoupling and filtering in automotive-grade systems
Procurement Notes
Verify the complete part number including the suffix MSTE03 to ensure correct FlexiCap and termination specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet revisions to validate electrical parameters against current production batches.
Selection Notes
Select this component when board flex resistance is critical for long-term reliability. The FlexiCap feature addresses common failure modes associated with rigid terminations in dynamic environments. Ensure the 100V rating and 27nF value align with circuit requirements before finalizing the bill of materials.
Part Context
This part belongs to the Knowles Syfer 1812Y series, which specializes in automotive-grade capacitors. The series integrates proprietary FlexiCap technology to enhance durability. It is designed specifically for applications where standard MLCCs may fail due to mechanical strain during assembly or operation.
Replacement Considerations
Substitutes must match the 1812 footprint, 100V rating, 27nF capacitance, X7R dielectric, and FlexiCap termination style. Verify that any alternative component also holds AEC-Q200 certification if automotive usage is required.
