1206J0500563MXTE07

Overview

The Knowles Syfer 1206J0500563MXTE07 is a three-terminal multilayer ceramic capacitor (MLCC) designed as an EMI filter. It features a capacitance of 56 nF with a tolerance of ±20% and utilizes X7R dielectric material. The component is rated for a DC voltage of 50V and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 surface-mount package, it incorporates a nickel barrier electrode structure terminated with 100% tin. This configuration provides effective electromagnetic interference suppression for high-frequency circuits.

Feature Summary

• Three-terminal architecture enables efficient common-mode noise attenuation
• Nickel barrier internal electrodes ensure robust solderability and reliability
• X7R dielectric maintains stable capacitance across wide temperature variations
• Surface-mount design facilitates automated assembly in compact layouts

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF circuit noise suppression
• Data bus protection against EMI

Procurement Notes

Verify the complete part number including suffixes to confirm specific termination and packaging details. Ensure compatibility with RoHS directives if required by your manufacturing standards. Cross-reference official datasheets for precise mechanical dimensions and recommended reflow soldering profiles to prevent thermal damage during assembly processes.

Selection Notes

Select this component when space-constrained designs require integrated filtering capabilities without additional discrete components. The 1206 footprint offers a balance between current handling capacity and board area efficiency. Consider the X7R characteristics for applications where moderate capacitance stability over temperature is sufficient compared to C0G/NP0 alternatives.

Part Context

This component belongs to the Knowles Syfer FlexiCap series of feedthrough capacitors. These devices are engineered specifically for high-frequency noise reduction in sensitive electronic systems. The series leverages advanced ceramic processing to achieve consistent performance in demanding environments, supporting modern miniaturization trends in consumer and industrial electronics.

Replacement Considerations

Consult manufacturer documentation for direct pin-compatible substitutes within the same series. Verify that alternative parts match the 50V rating, 56 nF capacitance, and 1206 package dimensions. Ensure any replacement maintains the three-terminal EMI filter topology to preserve circuit noise immunity specifications.
