1812J5000823MXTE03

Overview

The Knowles Syfer 1812J5000823MXTE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring an X7R dielectric and a capacitance of 82 nF. It operates at a DC voltage rating of 500 V with a tolerance of ±20%. The component utilizes a 1812 (4532 metric) case size and incorporates a nickel barrier electrode structure with 100% tin terminations. This configuration supports high-voltage applications requiring stable performance across the specified temperature range.

Feature Summary

• X2Y integrated circuit topology for enhanced electromagnetic interference suppression
• Nickel barrier internal electrode construction for robust high-voltage reliability
• 100% tin external termination finish ensuring solderability and environmental compliance

Applications

• High-voltage power supply filtering circuits
• Electromagnetic interference suppression in sensitive electronic systems
• Automotive electronics requiring X2Y noise reduction capabilities

Procurement Notes

Verify the specific suffix MXTE03 against the manufacturer datasheet to confirm the presence of the nickel barrier and X2Y topology, as standard variants may differ. Ensure compatibility with automated pick-and-place equipment regarding the 1812 package dimensions and terminal type. Confirm RoHS compliance status through official documentation prior to integration.

Selection Notes

Select this component when both high voltage handling and common-mode noise suppression are required within a single compact footprint. The X2Y architecture provides superior EMI performance compared to discrete capacitors. Evaluate the 500V rating against peak transient voltages in the target circuit to ensure adequate safety margins during operation.

Part Context

This part belongs to the Knowles Syfer MLCC portfolio, specifically designed for demanding industrial and automotive environments. The 1812J series designation indicates a general-purpose high-voltage line with specialized internal structures. The inclusion of the nickel barrier distinguishes it from standard silver-based electrodes, offering improved resistance to cracking and higher breakdown voltage stability.

Replacement Considerations

Direct substitutes must match the 82 nF capacitance, 500V rating, X7R dielectric, and 1812 package. Verify if the replacement offers identical X2Y functionality and nickel barrier construction. Generic X7R MLCCs without the X2Y topology will not provide equivalent noise suppression performance.
