1206Y0250154MJTE07

Overview

The Knowles Syfer 1206Y0250154MJTE07 is a three-terminal EMI filter capacitor housed in a 1206 (3216 metric) surface-mount package. It features an X7R dielectric with a capacitance of 0.15 µF and a voltage rating of 25 VDC. The component includes a nickel barrier termination structure designed for enhanced reliability. It supports a current rating of 2 A and is intended for high-reliability applications requiring effective electromagnetic interference suppression.

Feature Summary

• Three-terminal architecture providing superior high-frequency noise attenuation compared to standard two-terminal capacitors
• Integrated nickel barrier termination structure to improve mechanical robustness and solder joint integrity
• X7R dielectric material offering stable capacitance performance across a wide operating temperature range

Applications

• Electromagnetic interference filtering in sensitive electronic circuits
• Power supply input and output stages for noise suppression
• Signal line protection in high-reliability communication equipment

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and dielectric specifications. Confirm availability status through authorized distributors as stock levels fluctuate. Ensure compliance with RoHS directives and check for specific environmental certifications required by your project standards before finalizing procurement orders.

Selection Notes

Select this component when high-frequency EMI suppression is critical within a constrained 1206 footprint. The three-terminal design offers better isolation than standard MLCCs. Verify that the 25 VDC rating and 2 A current handling meet circuit requirements. Consider the nickel barrier termination if mechanical stress resistance during assembly or operation is a priority for the application.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability multilayer ceramic capacitors. The series is engineered for demanding environments where standard components may fail due to mechanical stress or thermal cycling. The 1206Y prefix indicates a specific form factor within the broader Syfer portfolio focused on robust surface-mount solutions.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 0.15 µF capacitance, 25 V rating, and three-terminal EMI filter configuration. Verify that alternative parts support the same X7R dielectric characteristics and current handling capabilities. Ensure compatible termination materials for reliable soldering processes.
