Overview
The Knowles Syfer 1812Y0500562MJTE03 is a multilayer ceramic capacitor (MLCC) in an 1812 surface-mount package. It features a capacitance of 5.60 nF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material and is certified to AEC-Q200 standards for automotive applications. It incorporates FlexiCap technology with a nickel barrier to enhance mechanical reliability under board flex conditions.
Feature Summary
- X2Y architecture providing integrated common-mode noise suppression
- FlexiCap soft termination design for board flex sensitivity
- Nickel barrier electrode structure for enhanced durability
Applications
- Automotive electronics requiring AEC-Q200 compliance
- High-density circuit boards susceptible to mechanical stress
- Signal lines requiring integrated EMI filtering
Procurement Notes
Verify the specific suffix 'MJTE03' against official datasheets to confirm the X2Y configuration, as standard Y-series parts may differ. Ensure compatibility with reflow soldering profiles specified by Knowles Syfer for FlexiCap terminations. Confirm RoHS compliance status through current manufacturer documentation before integration.
Selection Notes
Select this component when space-constrained designs require combined decoupling and filtering functions. The X2Y topology reduces external component count compared to discrete solutions. Evaluate board flex requirements to justify the FlexiCap termination over standard rigid terminations for improved lifecycle reliability.
Part Context
This part belongs to the Knowles Syfer 1812Y series, which focuses on high-reliability capacitors for automotive and industrial sectors. The series emphasizes mechanical robustness through specialized termination technologies like FlexiCap, addressing failure modes associated with PCB warping during assembly or operation.
Replacement Considerations
Direct substitutes must match the 1812 footprint, 5.6 nF value, 50V rating, and X2Y functionality. Generic X7R MLCCs lack the integrated filtering capability. Verify pinout compatibility if replacing with other X2Y variants from different manufacturers.
