0805J0500333MXTE07

Overview

The Knowles Syfer 0805J0500333MXTE07 is a three-terminal EMI filter capacitor housed in an 0805 (2012 metric) surface-mount package. It features a capacitance of 0.033 µF with a ±20% tolerance 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. End terminations consist of a nickel barrier with 100% tin plating, 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 designs
• Nickel barrier and 100% tin end terminations ensure robust solderability and corrosion resistance
• X7R dielectric formulation maintains stable capacitance characteristics across the specified industrial temperature range

Applications

• High-reliability electronic systems requiring stringent EMI filtering
• Automotive grade circuits compliant with AEC-Q200 standards
• Power supply input/output stages for noise suppression

Procurement Notes

Verify the complete part number including the suffix MXTE07 to confirm the three-terminal EMI filter configuration. Standard MLCCs may share similar base codes but lack the specific shielding structure. Confirm RoHS compliance and REACH status through official manufacturer documentation prior to integration.

Selection Notes

Select this component when superior common-mode noise rejection is required in space-constrained designs. The three-terminal structure offers lower parasitic inductance than conventional capacitors. Ensure the PCB footprint accommodates the center ground terminal distinct from the signal path terminals.

Part Context

This component belongs to the Knowles Syfer XT series of high-reliability multilayer ceramic capacitors. The series is engineered for demanding environments where long-term stability and EMI performance are critical. The 0805 form factor allows for compact board layouts while maintaining the electrical integrity required for sensitive signal lines.

Replacement Considerations

Public confirmed substitute part numbers include 0805J0630333JDT and 0805J1000333JDT. Verify that any replacement maintains the three-terminal EMI filter topology and compatible termination materials.
