1812Y5000103MJTE03

Overview

The Knowles Syfer 1812Y5000103MJTE03 is a multilayer ceramic capacitor (MLCC) in an 1812 surface-mount package. It features a capacitance of 10 nF with a ±20% tolerance and a DC voltage rating of 50 V. The component utilizes X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. It incorporates a nickel barrier electrode structure with 100% tin terminations for reliable soldering. This part belongs to the FlexiCap series, designed for applications requiring board flexibility.

Feature Summary

• X2Y architecture providing integrated common-mode noise suppression
• FlexiCap flexible termination design to reduce mechanical stress on the PCB
• Nickel barrier electrode construction for enhanced reliability

Applications

• High-reliability circuits requiring board flexibility
• Noise filtering in sensitive electronic systems
• Applications subject to mechanical vibration or thermal cycling

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal plating and dielectric characteristics. Ensure compatibility with automated placement equipment regarding the flexible termination style. Cross-reference RoHS compliance status with current manufacturer declarations prior to integration into regulated products.

Selection Notes

Select this component when space constraints require an 1812 footprint combined with integrated EMI filtering capabilities. The X7R dielectric offers a balance of capacitance density and temperature stability suitable for general-purpose decoupling. Consider the flexible terminations if the application involves significant PCB flexing or high-vibration environments.

Part Context

This capacitor is part of the Knowles Syfer FlexiCap family, which specializes in components with compliant terminations. The Y-series designation typically indicates X7R dielectric characteristics within this product line. The 1812 case size provides a higher capacitance volume compared to smaller footprints while maintaining standard SMT mounting profiles.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 50V rating, 10nF value, and X2Y topology. Generic MLCCs lack the integrated filtering function. Verify that alternative parts support flexible terminations if mechanical stress relief is required.
