1206J0500683MXTE07

Overview

The Knowles Syfer 1206J0500683MXTE07 is a surface-mount multilayer ceramic capacitor designed as a three-terminal EMI filter. It features a 1206 (3216 metric) package with a capacitance of 68 nF, a DC voltage rating of 50 V, and an X7R dielectric offering ±20% tolerance. The component utilizes a nickel barrier termination system with 100% tin plating to ensure reliable soldering. Rated for operation between -55°C and +125°C, it provides effective electromagnetic interference suppression in compact electronic assemblies.

Feature Summary

• Three-terminal architecture functions as an integrated EMI filter within the capacitor structure
• Nickel barrier termination system ensures robust mechanical stability and solderability
• X7R dielectric material maintains stable capacitance characteristics across the operating temperature range

Applications

• High-frequency noise suppression in power supply input lines
• Electromagnetic interference filtering in telecommunications equipment
• Signal integrity protection in automotive electronics modules

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to confirm specific termination and packaging details. Ensure compatibility with standard reflow soldering profiles for nickel-barrier components. Confirm that the selected variant meets all required environmental compliance standards for the intended application before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require simultaneous decoupling and high-frequency noise attenuation. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors due to reduced parasitic inductance. Consider the 1206 footprint availability and ensure the 50V rating exceeds the maximum circuit voltage with appropriate derating margins.

Part Context

This component belongs to the Knowles Syfer series of specialized multilayer ceramic capacitors engineered for demanding environments. The product line emphasizes reliability and consistent electrical performance for critical applications. These filters integrate passive filtering capabilities directly into the mounting footprint, simplifying board layout while maintaining signal quality in sensitive electronic circuits.

Replacement Considerations

Cross-reference alternative three-terminal EMI filters from other manufacturers only if they match the 1206 footprint, 68 nF capacitance, 50V rating, and X7R dielectric type. Verify that substitute components maintain equivalent parasitic inductance specifications and termination metallurgy to ensure identical thermal and mechanical behavior during assembly.
