1812J5000104MXTE03

Overview

The Knowles Syfer 1812J5000104MXTE03 is a surface-mount feed-through multilayer ceramic capacitor. It features a capacitance of 0.1 µF with an X7R dielectric and a DC voltage rating of 500 V. The component operates within a temperature range of -55°C to +125°C. It utilizes a 1812 (4532 metric) package size and includes a 50 mA current rating for its feed-through architecture.

Feature Summary

• Integrates feed-through functionality for enhanced electromagnetic interference suppression in compact designs.
• Utilizes X7R dielectric material to maintain stable capacitance characteristics across the operating temperature range.
• Supports high-voltage applications through a 500 VDC rating while maintaining a low-profile surface-mount form factor.

Applications

• High-frequency signal filtering in electronic circuits
• Power supply input/output noise reduction
• Electromagnetic interference suppression in sensitive instrumentation

Procurement Notes

Verify the specific suffix E03 confirms the feed-through variant, as standard MLCCs lack this feature. Confirm the 50 mA current rating aligns with circuit requirements. Check RoHS compliance status via official datasheets. Ensure the 1812 footprint matches PCB layout constraints. Validate manufacturer authenticity through authorized channels.

Selection Notes

Select this component when integrated EMI filtering is required without additional discrete components. The 500V rating provides headroom for transient voltages. The X7R dielectric offers higher capacitance density than Class 1 alternatives. Verify that the 50 mA current handling meets the application's peak load demands. Consider the 1812 package dimensions for spatial limitations.

Part Context

This part belongs to the Knowles Syfer 1812J series of general-purpose and specialized MLCCs. The J designation typically indicates a 500V rating within this family. The E03 suffix distinguishes it as a feed-through type, differing from standard parallel-plate capacitors like the 1812J5000104KXT.

Replacement Considerations

Standard 1812J5000104 variants lack feed-through capabilities and cannot replace this part directly. Substitutes must match the 500V rating, 0.1µF value, and 1812 footprint. Verify if alternative manufacturers offer equivalent feed-through MLCCs with compatible current ratings.
