1206Y0500204MJTE07

Overview

The Knowles Syfer 1206Y0500204MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a 50V DC voltage rating and a capacitance of 200nF with a ±20% tolerance, utilizing X7R dielectric material. The component operates within a temperature range of -55°C to +125°C. It employs a FlexiCap™ nickel barrier termination system with 100% tin plating to enhance mechanical reliability under board flex conditions. The device is housed in a standard 1206 (3216 metric) package.

Feature Summary

• Three-terminal architecture provides effective electromagnetic interference filtering for high-frequency noise suppression.
• FlexiCap™ nickel barrier terminations offer superior resistance to mechanical stress and board flex-induced cracking.
• X7R dielectric ensures stable capacitance performance across the specified industrial operating temperature range.

Applications

• Electromagnetic interference filtering in automotive electronic control units
• Power supply input/output decoupling in flexible circuit assemblies
• Noise suppression in sensitive signal lines for board-flex applications

Procurement Notes

Verify the complete part number including the suffix MJTE07 to ensure correct termination and tolerance specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet electrical characteristics against specific circuit requirements to validate performance under operational loads.

Selection Notes

Select this component when board flex reliability is critical due to its specialized termination structure. The three-terminal design is preferred over standard two-terminal MLCCs for superior high-frequency attenuation. Ensure the 1206 footprint aligns with existing PCB layout constraints and that the 50V rating exceeds the maximum circuit voltage with adequate margin.
