1206J0250223MJTE07

Overview

The Knowles Syfer 1206J0250223MJTE07 is a three-terminal EMI filter capacitor in a 1206 (3216 metric) surface-mount package. It features an X7R dielectric with a capacitance of 22 nF and a DC voltage rating of 25 VDC. The component offers a tolerance of ±20% and operates within a temperature range of -55°C to +125°C. It utilizes FlexiCap technology with a nickel barrier termination, designed for high-reliability applications requiring effective electromagnetic interference suppression.

Feature Summary

• Three-terminal architecture provides enhanced high-frequency noise attenuation compared to standard two-terminal capacitors.
• FlexiCap construction with nickel barrier terminations ensures robust mechanical integrity and reliable soldering performance.
• X7R dielectric material maintains stable capacitance characteristics across the specified operating temperature range.

Applications

• High-frequency noise filtering in sensitive electronic circuits
• Power supply input/output decoupling for EMI suppression
• Signal line protection in communication equipment

Procurement Notes

Verify the complete part number including the suffix to confirm the specific termination style and packaging configuration. Ensure compatibility with automated pick-and-place equipment regarding the reel specifications. Confirm that the three-terminal footprint matches the design layout, as pin spacing differs from standard MLCCs. Check for any specific handling requirements related to the nickel barrier plating during assembly processes.

Selection Notes

Select this component when superior high-frequency EMI performance is required over standard capacitors in a compact 1206 footprint. The three-terminal design is critical for applications where parasitic inductance must be minimized. Consider the 25V rating and 22nF value against circuit requirements. Verify that the PCB land pattern supports the specific terminal arrangement of this EMI filter type rather than a conventional capacitor.

Part Context

This component belongs to the Knowles Syfer FlexiCap series of ceramic EMI filters. These parts integrate capacitor functionality with shielding properties inherent to the three-terminal structure. The series targets automotive and industrial sectors demanding high reliability. The 1206 size allows for dense board layouts while providing better noise suppression than equivalent two-terminal devices.

Replacement Considerations

Direct substitutes require matching the three-terminal configuration and 1206 footprint. Standard two-terminal capacitors will not provide equivalent EMI filtering performance. Verify that alternative parts support the same voltage rating and capacitance tolerance. Ensure the replacement also utilizes compatible termination materials for the intended soldering process.
