1812J1000123MJTE03

Overview

The Knowles Syfer 1812J1000123MJTE03 is a surface-mount feed-through capacitor with a capacitance of 0.012 µF and a voltage rating of 100 VDC. It utilizes X7R dielectric material, offering ±20% tolerance within an operating temperature range of -55°C to +125°C. The component features a 1812 (4532 metric) package size and incorporates a nickel barrier with 100% tin termination. Designed as an X2Y device, it integrates filtering capabilities directly into the passive component structure.

Feature Summary

• Integrates feed-through filtering functionality within a standard surface-mount footprint
• Utilizes X2Y architecture for enhanced electromagnetic interference suppression
• Features nickel barrier terminations with 100% tin plating for reliable soldering

Applications

• High-density circuit boards requiring integrated EMI filtering
• Automotive electronics systems
• Boardflex sensitive applications

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct termination and dielectric specifications. Confirm availability through authorized distributors as lead times may vary. Ensure compatibility with automated pick-and-place equipment regarding the 1812 package dimensions.

Selection Notes

Select this component when space constraints require combining decoupling and filtering functions in a single surface-mount device. The X2Y topology provides superior noise reduction compared to standard capacitors. Verify that the 100V rating meets the circuit's peak voltage requirements and that the X7R characteristics align with the thermal environment.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, designed for automotive and industrial applications. It represents a specialized category of MLCCs that combine passive energy storage with active signal conditioning. The 1812J series indicates high-reliability construction suitable for demanding environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Direct replacements must match the X2Y feed-through topology and 1812 package dimensions.
