0805J0250391MCTE01

Overview

The Knowles Syfer 0805J0250391MCTE01 is a surface-mount multilayer ceramic capacitor (MLCC) designed for general electronic applications. It features a capacitance of 390 pF with a tolerance of ±20% and a DC voltage rating of 25 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range from -55°C to +125°C. Housed in a standard 0805 (2012 metric) package, it employs SMD/SMT terminations for automated assembly.

Feature Summary

• Utilizes C0G (NP0) dielectric for high stability and low loss characteristics
• Designed for surface mount technology (SMD/SMT) integration
• Operates reliably within extended industrial temperature ranges

Applications

• General purpose circuit filtering
• High-frequency signal coupling
• Resonant tank circuits

Procurement Notes

Verify the specific suffix 'TE01' against official manufacturer documentation to confirm packaging configuration and terminal specifications. Ensure compatibility with existing PCB footprint dimensions and reflow soldering profiles. Cross-reference the Mouser part number 843-0805J0250391MC1 for availability status and updated datasheet revisions before finalizing procurement plans.

Selection Notes

Select this component when a compact 0805 form factor is required for low-capacitance applications. The C0G dielectric ensures minimal capacitance drift with voltage and temperature changes, making it suitable for precision timing or RF circuits. Confirm that the 25V rating provides adequate margin for the specific application's peak voltage stresses.

Part Context

This component belongs to the Knowles Syfer MLCC portfolio, which specializes in high-reliability ceramic capacitors. The 0805J series indicates a standard commercial grade device within the 0805 footprint family. These components are widely used in consumer electronics, telecommunications, and industrial control systems where space constraints and reliability are critical design factors.

Replacement Considerations

Official substitutes include other Knowles Syfer parts with matching 0805 footprints and C0G dielectrics. Verify equivalent capacitance, voltage rating, and tolerance before substitution. Generic equivalents from other manufacturers require careful evaluation of physical dimensions and electrical characteristics.
