1206J0500682MXTE01

Overview

The Knowles Syfer 1206J0500682MXTE01 is a three-terminal EMI filter capacitor in a 1206 (3216 metric) surface-mount package. It features a capacitance of 6.8 nF with a ±20% tolerance and an X7R dielectric. The device has a DC voltage rating of 50 VDC and operates within a temperature range of -55°C to +125°C. It utilizes a nickel barrier with 100% tin termination for soldering.

Feature Summary

• Three-terminal feedthrough architecture provides superior high-frequency electromagnetic interference suppression compared to standard two-terminal capacitors.
• Nickel barrier end-termination system ensures reliable solderability and mechanical stability during surface-mount assembly processes.

Applications

• High-density printed circuit board layouts requiring effective noise filtering in limited space
• Power supply input and output stages for decoupling and transient suppression
• Signal lines in sensitive electronic equipment requiring EMI mitigation

Procurement Notes

Verify the complete part number including the suffix to confirm the specific termination material and tolerance class. Ensure the procurement documentation explicitly states the three-terminal configuration, as this distinguishes it from standard MLCCs. Confirm RoHS compliance status through official manufacturer declarations prior to finalizing orders.

Selection Notes

Select this component when high-frequency noise attenuation is critical in compact designs. The three-terminal structure offers lower parasitic inductance than conventional capacitors. Verify that the 50V DC rating meets the circuit's peak voltage requirements and that the X7R dielectric characteristics align with the operating temperature stability needs.

Part Context

This component belongs to the Knowles Syfer family of multilayer ceramic capacitors designed for surface-mount technology. It represents a specialized category of EMI filters that integrate shielding properties directly into the capacitor structure, providing enhanced performance in noise-sensitive applications without requiring additional external components.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 6.8 nF capacitance, 50V rating, and three-terminal feedthrough design. Standard two-terminal capacitors are not functionally equivalent due to differences in parasitic inductance and filtering efficiency.
