Overview
The Knowles Syfer 1812Y0500474MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features an X7R dielectric with a capacitance of 470 nF and a DC voltage rating of 50V. The component utilizes the FlexiCap termination technology, which incorporates a proprietary flexible material to withstand board bending and thermal cycling stress. It is housed in a standard 1812 (4532 metric) case size and includes a nickel barrier layer within the termination structure.
Feature Summary
- FlexiCap flexible termination technology enhances mechanical reliability under board flexing and thermal cycling conditions
- Integrated nickel barrier layer provides robust protection against solder wicking during assembly
- X7R dielectric ensures stable capacitance performance across the specified operating temperature range
Applications
- Automotive electronics requiring AEC-Q200 qualification
- Space-qualified electronic systems
- Board-flex sensitive circuit designs
Procurement Notes
Verify the specific suffix E07 indicates the 3-terminal EMI filter configuration when sourcing. Confirm RoHS compliance status and REACH registration details directly from the manufacturer's current documentation. Ensure the procurement channel provides valid traceability records for high-reliability components.
Selection Notes
Select this component for applications demanding superior mechanical durability compared to standard MLCCs. The FlexiCap design mitigates cracking risks associated with PCB warpage. Verify that the 50V rating and 470 nF capacitance align with the circuit requirements before integration.
