0805J0250333MXTE01

Overview

The Knowles Syfer 0805J0250333MXTE01 is a three-terminal feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.033 µF with a voltage rating of 25V DC and a current rating of 300 mA. The component utilizes an X7R dielectric material housed in an 0805 (2012 metric) surface-mount package. It operates within a temperature range of -55°C to +125°C and provides effective electromagnetic interference filtering through its integrated ground terminal.

Feature Summary

• Three-terminal architecture integrates signal, ground, and power paths for superior high-frequency attenuation
• Feed-through design minimizes parasitic inductance compared to standard two-terminal capacitors
• X7R dielectric ensures stable capacitance performance across the specified operating temperature range

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF circuit noise suppression

Procurement Notes

Verify the specific suffix MXTE01 against official datasheets to confirm the exact termination plating and packaging configuration. Ensure compatibility with automated pick-and-place equipment regarding the 0805 footprint dimensions. Confirm that the 300 mA current rating meets the application requirements without derating issues at elevated temperatures.

Selection Notes

Select this component when low parasitic inductance is critical for EMI reduction. The three-terminal structure offers better performance than standard MLCCs at high frequencies. Verify that the 25V DC rating exceeds the maximum circuit voltage including transients. Consider the 0805 size constraints relative to available PCB real estate.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which specializes in compact EMI filtering solutions. These components are engineered to replace traditional discrete filter networks, saving board space while maintaining signal integrity in dense electronic assemblies.

Replacement Considerations

Direct substitutes must match the 0805 footprint, 0.033 µF capacitance, 25V rating, and three-terminal feed-through topology. Verify equivalent current handling capabilities and thermal stability.
