1206J2000393MJTE07

Overview

The Knowles Syfer 1206J2000393MJTE07 is a three-terminal EMI filter capacitor in a 1206 surface-mount package. It features a capacitance of 0.039 µF with a tolerance of ±20% and an X7R dielectric. The rated voltage is 200 V DC, and it utilizes a nickel barrier with 100% tin terminations.

Feature Summary

• Three-terminal architecture for enhanced electromagnetic interference filtering
• Nickel barrier termination system ensuring reliable solderability
• X7R ceramic dielectric providing stable capacitance over temperature

Applications

• High-frequency noise suppression in electronic circuits
• Power line filtering for sensitive components
• EMI mitigation in compact surface-mount designs

Procurement Notes

Verify the specific revision level and termination finish against the official datasheet before integration. Confirm that the three-terminal configuration aligns with the PCB footprint requirements. Ensure the 200 V DC rating meets the circuit's maximum operating voltage under all conditions.

Selection Notes

Select this component when high-density EMI filtering is required in a standard 1206 footprint. The three-terminal design offers superior attenuation compared to two-terminal capacitors. Verify compatibility with automated assembly processes given the nickel barrier termination style.

Part Context

This part belongs to the Knowles Syfer MLCC series designed for robust performance in demanding environments. The 1206J prefix indicates the case size and voltage class within the manufacturer's portfolio. It is distinct from standard two-terminal capacitors due to its integrated filtering structure.

Replacement Considerations

Direct substitutes must match the 1206J2000393MJTE07 designation exactly to ensure pinout and electrical compatibility. Alternative three-terminal filters may require footprint modification if dimensions differ.
