1206Y0500102MJTE03

Overview

The Knowles Syfer 1206Y0500102MJTE03 is a three-terminal feed-through multilayer ceramic capacitor (MLCC) in a 1206 surface-mount package. It features a capacitance of 1000 pF with a ±20% tolerance and an X7R dielectric. The component has a DC voltage rating of 50 V and operates within a temperature range of -55°C to +125°C. Designed for EMI suppression, it includes a nickel barrier and flexible soft terminals.

Feature Summary

• Three-terminal feed-through architecture provides superior high-frequency EMI filtering performance compared to standard two-terminal capacitors.
• Flexible soft terminal construction enhances mechanical reliability by absorbing board flex stress and preventing solder joint cracking.
• Nickel barrier electrode structure ensures robust termination integrity and compatibility with standard reflow soldering processes.

Applications

• High-frequency electromagnetic interference (EMI) suppression in sensitive electronic circuits
• Power line filtering for noise reduction in automotive and industrial control systems
• Signal integrity protection in communication equipment requiring stable high-frequency performance

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct terminal configuration and material specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference datasheet electrical parameters with design constraints to validate suitability for specific thermal and electrical operating conditions.

Selection Notes

Select this component when high-frequency noise attenuation is critical and board flexibility may compromise standard MLCC joints. The three-terminal design offers lower parasitic inductance than conventional packages. Ensure the application environment remains within the specified -55°C to +125°C operational range to maintain X7R dielectric stability and long-term reliability.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability MLCCs featuring soft terminations. The 1206Y prefix indicates a 1206 metric footprint with specific internal construction optimized for durability. As a feed-through type, it integrates filtering directly into the circuit path, distinguishing it from standard decoupling capacitors.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with any alternative components by matching capacitance, voltage rating, package dimensions, and three-terminal feed-through topology.
