0805J0500392MJTE07

Overview

The Knowles Syfer 0805J0500392MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) housed in an 0805 (2012 metric) package. It features a capacitance of 3900 pF with a tolerance of ±20% and a rated DC voltage of 50V. The component utilizes X7R dielectric material, providing stable performance across a wide operating temperature range from -55°C to +125°C. This specific part number denotes the X2Y three-terminal architecture, which integrates internal shielding for enhanced electromagnetic interference suppression.

Feature Summary

• X2Y three-terminal architecture provides integrated common-mode noise filtering within a standard two-terminal footprint
• Internal electrode shielding design offers superior electromagnetic interference suppression compared to conventional MLCCs
• High-temperature stability ensured by X7R dielectric characteristics suitable for demanding thermal environments

Applications

• High-reliability automotive electronics requiring AEC-Q200 compliance
• Data communication interfaces needing effective common-mode noise reduction
• Sensitive analog circuitry requiring compact EMI filtering solutions

Procurement Notes

Verify the complete part number including the suffix to confirm the specific termination plating and reel packaging configuration. Ensure compatibility with automated pick-and-place equipment regarding tape and reel dimensions. Cross-reference official manufacturer documentation for current lifecycle status and recommended soldering profiles to guarantee assembly integrity.

Selection Notes

Select this component when space-constrained designs require simultaneous decoupling and noise filtering capabilities. The X2Y structure allows designers to replace separate filter components, reducing board area. Confirm that the 50V rating exceeds the maximum circuit voltage under all operating conditions, including transients.

Part Context

This component belongs to the Knowles Syfer 0805J series, specialized for high-reliability applications. The series is widely utilized in industries where failure rates must be minimized, such as aerospace and medical devices. The X2Y technology represents a distinct product line within the broader MLCC portfolio, focusing on signal integrity rather than simple energy storage.

Replacement Considerations

Direct substitutes include other X2Y capacitors from Knowles Syfer with identical capacitance and voltage ratings but different tolerances or terminations. Generic MLCCs cannot replicate the internal shielding and common-mode filtering performance of the X2Y architecture without altering the circuit layout.
