1812J5000273MJTE03

Overview

The Knowles Syfer 1812J5000273MJTE03 is a feed-through capacitor with a capacitance of 0.027 µF and a voltage rating of 500V. It utilizes C0G/NP0 dielectric material for stability. The component operates within a temperature range of -55°C to +125°C. It features a 1812 (4532 metric) package size and includes a nickel barrier termination system. The device supports a maximum current of 50 mA.

Feature Summary

• Feed-through architecture providing integrated filtering capabilities
• High-reliability construction suitable for demanding environments
• Nickel barrier termination ensuring robust solder joint integrity

Applications

• High-frequency signal filtering in sensitive circuits
• Power supply input/output decoupling
• EMI suppression in aerospace or military systems

Procurement Notes

Verify the specific suffix 'MJTE03' against official datasheets to confirm the feed-through configuration and termination type. Ensure compatibility with high-current requirements up to 50 mA. Confirm RoHS compliance status through manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when a surface-mount feed-through solution is required for EMI reduction. The 1812 package offers a balance between current handling and board space. Verify that the 500V rating exceeds circuit peak voltages. Consider the nickel barrier terminations for applications requiring enhanced mechanical strength during thermal cycling.

Part Context

This part belongs to the Knowles Syfer high-reliability MLCC family. These components are designed for harsh environments where standard capacitors may fail. The feed-through design integrates shielding directly into the component body, reducing the need for external shielding cans.

Replacement Considerations

Direct substitutes must match the 0.027 µF value, 500V rating, and feed-through form factor. Verify termination compatibility. Generic MLCCs lack the internal feed-through structure and shielding properties.
