1812J1000474MXTE07

Overview

The Knowles Syfer 1812J1000474MXTE07 is a multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features an X7R dielectric with a capacitance of 470 nF and a DC voltage rating of 100 VDC. The component utilizes a flexible termination system to enhance mechanical reliability under thermal cycling conditions. It operates within a temperature range of -55°C to +125°C and is housed in a standard 1812 (4532 metric) surface-mount package.

Feature Summary

• Three-terminal architecture for effective electromagnetic interference filtering
• Flexible termination technology to withstand board bending and thermal stress
• X7R dielectric material providing stable capacitance characteristics

Applications

• High-frequency noise suppression in electronic circuits
• Power supply input/output filtering stages
• Signal line protection against electromagnetic interference

Procurement Notes

Verify the specific suffix 'E07' against official manufacturer documentation to confirm packaging configuration and terminal plating specifications. Ensure that the flexible termination requirements align with the target assembly process, as these components may require distinct handling protocols compared to standard rigid-termination MLCCs during placement.

Selection Notes

Select this component when integrated EMI filtering and high mechanical robustness are required in a compact footprint. The three-terminal design offers superior noise attenuation compared to two-terminal capacitors. Consider the 100V rating and 470nF value to ensure compatibility with the circuit's operating voltage and impedance matching requirements without exceeding thermal limits.

Part Context

This part belongs to the Syfer Flexicap series, which incorporates proprietary flexible termination materials to improve reliability in harsh environments. The series has been qualified for space applications and recognized for innovation. The 1812J1000474MXTE07 specifically integrates filtering capabilities into the standard MLCC form factor, combining decoupling and noise suppression functions.

Replacement Considerations

Direct substitutes must match the three-terminal EMI filter topology, 1812 package size, 100V rating, and X7R dielectric. Verify that alternative parts support flexible terminations if mechanical stress resistance is critical. Standard two-terminal MLCCs cannot replace this component due to the lack of integrated filtering functionality.
