1206J0250334MXTE07

Overview

The Knowles Syfer 1206J0250334MXTE07 is a three-terminal feed-through multilayer ceramic capacitor designed for surface-mount applications. It features a capacitance of 0.33 µF with a tolerance of ±20% and a DC voltage rating of 25 VDC. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range of -55°C to +125°C. Constructed in a 1206 (3216 metric) package, it incorporates a nickel barrier termination system with 100% tin plating. This configuration provides effective electromagnetic interference filtering capabilities within compact circuit layouts.

Feature Summary

• Three-terminal feed-through architecture for enhanced high-frequency noise suppression
• Nickel barrier termination structure combined with 100% tin plating for reliable solderability
• X7R dielectric composition providing stable capacitance characteristics over wide temperature variations

Applications

• Electromagnetic interference filtering in sensitive electronic circuits
• Power supply line conditioning for noise reduction
• Signal integrity protection in high-speed digital systems

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and dielectric specifications. Confirm RoHS compliance status through current datasheets as regulatory requirements may evolve. Cross-reference distributor listings with original manufacturer data to validate authenticity and avoid counterfeit components during sourcing processes.

Selection Notes

Select this component when integrated EMI filtering is required without additional discrete inductors. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Ensure the PCB layout supports the specific pad geometry required for feed-through configurations to maximize shielding effectiveness and minimize parasitic inductance in the signal path.

Part Context

This component belongs to the Knowles Syfer MLCC series, specifically engineered for demanding environments requiring robust noise suppression. The 1206J series denotes general-purpose reliability with specialized filtering capabilities. It represents a solution for designers needing to manage conducted emissions while maintaining small form factors in modern electronic assemblies.

Replacement Considerations

Direct substitutes must match the three-terminal feed-through topology and 1206 footprint. Verify that alternative parts maintain equivalent capacitance, voltage rating, and termination materials to ensure compatibility with existing thermal profiles and soldering processes.
