1812Y5000683MSTE03

Overview

The Knowles Syfer 1812Y5000683MSTE03 is a feed-through multilayer ceramic capacitor (MLCC) in an 1812 surface-mount package. It features a capacitance of 0.068 µF with a DC voltage rating of 500 V and a current rating of 50 mA. The component utilizes X7R dielectric material and incorporates FlexiCap technology with a nickel barrier for enhanced mechanical reliability.

Feature Summary

• Integrated feed-through architecture providing combined capacitance and shielding functionality
• FlexiCap flexible termination design to mitigate board flex stress
• Nickel barrier layer integrated within the termination structure

Applications

• High-voltage power supply filtering
• EMI suppression in sensitive electronic circuits
• Board-flex sensitive applications requiring robust terminations

Procurement Notes

Verify the specific suffix MSTE03 against official datasheets to confirm the feed-through configuration and nickel barrier inclusion, as standard MLCCs lack these features. Ensure compatibility with high-voltage PCB layouts and thermal profiles during assembly.

Selection Notes

Select this component when both high-voltage filtering and structural integrity under mechanical stress are required. The feed-through design simplifies layout by integrating shielding, while the flexible terminations protect against solder joint failure in dynamic environments.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability capacitors for demanding environments. The 1812Y series typically offers high voltage ratings and robust construction suitable for industrial and automotive applications where standard MLCCs might fail due to mechanical strain.

Replacement Considerations
