Overview
The Knowles Syfer 1812Y1000103MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) from the FlexiCap series. It features a 10 nF capacitance with a ±20% tolerance and a DC voltage rating of 100 VDC. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) case size, it employs flexible soft termination technology for enhanced mechanical reliability.
Feature Summary
- Flexible soft termination design reduces stress on pads during board flexing
- X7R dielectric provides stable capacitance across wide temperature ranges
- Surface mount construction suitable for automated assembly processes
Applications
- Board-flex sensitive circuit designs
- General purpose decoupling applications
- High-reliability industrial electronics
Procurement Notes
Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination style and tolerance specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to align with assembly process constraints.
Selection Notes
Select this component when board flex resistance is critical due to its flexible termination structure. Ensure the 100V DC rating and X7R temperature characteristics meet the specific circuit requirements. Verify that the 1812 footprint matches the PCB layout design constraints.
Part Context
This component belongs to the Knowles Syfer FlexiCap family, which specializes in MLCCs with compliant terminations. These capacitors are engineered to mitigate cracking risks associated with mechanical stress in rigid printed circuit boards, offering improved durability compared to standard rigid-termination counterparts.
Replacement Considerations
Substitutes must match the 1812 package, 10nF capacitance, 100V rating, and X7R dielectric. Flexible termination compatibility is essential for maintaining mechanical integrity in flex-sensitive applications.
