0805J0250123MJTE07

Overview

The Knowles Syfer 0805J0250123MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a 0.012 µF capacitance with ±20% tolerance and a 25 VDC voltage rating. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Packaged in the standard 0805 (2012 metric) case size, it integrates a central conductor structure optimized for EMI filtering applications.

Feature Summary

• Integrates a central conductor architecture to provide effective electromagnetic interference filtering within a compact footprint.
• Utilizes C0G (NP0) ceramic dielectric technology to maintain consistent electrical characteristics under varying thermal conditions.
• Designed for surface-mount assembly processes, facilitating automated placement on printed circuit boards.

Applications

• High-frequency noise suppression in signal lines
• Electromagnetic interference (EMI) filtering in communication modules
• Power distribution network decoupling

Procurement Notes

Verify that the specific ordering suffix matches the required termination and packaging configuration. Confirm the component is identified as a feed-through type rather than a standard multilayer ceramic capacitor to ensure correct circuit topology. Check RoHS compliance status against current regulatory requirements before finalizing procurement specifications.

Selection Notes

Select this component when space-constrained EMI filtering is required in low-voltage signal paths. The 0805 package offers a balance between current handling capability and board area efficiency. Ensure the application voltage remains below the 25 VDC rating to maintain reliability and prevent dielectric breakdown during operation.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor family, distinct from their general-purpose MLCC series. These components are engineered specifically for noise suppression, combining capacitive coupling with a grounded center pin to shunt high-frequency interference effectively while passing desired signals.

Replacement Considerations

Direct substitutes include the 0805Y0250123MJTE07 variant, which shares identical electrical parameters and form factor. Verify compatibility regarding terminal finish and reel packaging specifications when cross-referencing alternative sources or distributors.
