1812J1000334MXTE07

Overview

The Knowles Syfer 1812J1000334MXTE07 is a feedthrough multilayer ceramic capacitor (MLCC) in the FlexiCap series. It features a 0.33 µF capacitance with ±20% tolerance and a 100 V DC voltage rating. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) surface-mount package, it incorporates flexible terminals designed to mitigate stress during board flexing.

Feature Summary

• Feedthrough architecture providing integrated EMI filtering capabilities within the component structure
• Flexible terminal design engineered to withstand mechanical stress associated with board flex applications
• X7R dielectric composition offering stable capacitance performance across wide industrial temperature ranges

Applications

• Automotive electronics requiring AEC-Q200 qualification standards
• Boardflex-sensitive circuit assemblies demanding enhanced mechanical durability
