1812Y1000153MJTE03

Overview

The Knowles Syfer 1812Y1000153MJTE03 is a feed-through multilayer ceramic capacitor in an 1812 (4532 metric) package. It features a capacitance of 0.015 µF with a rated DC voltage of 100V and a maximum current rating of 50 mA. The component utilizes X7R dielectric material, offering a tolerance of ±20%. Designed for surface mount installation, it operates within a temperature range of -55°C to +125°C. This part integrates three PCB pads for its feed-through architecture.

Feature Summary

• Integrates feed-through architecture utilizing three PCB pads for direct signal path connection
• Provides electromagnetic interference suppression through integrated capacitive filtering
• Features flexible terminal construction to enhance reliability under board flex conditions

Applications

• High-frequency signal line filtering in automotive electronics
• EMI suppression in sensitive communication interfaces
• Power distribution networks requiring integrated decoupling

Procurement Notes

Verify the specific suffix JTE03 against official datasheets to confirm the feed-through configuration and three-pad footprint. Ensure design compatibility with the required 50 mA current rating and 100V DC operating voltage. Confirm that the X7R dielectric characteristics meet the thermal stability requirements for the intended application environment.

Selection Notes

Select this component when a combined filtering and mounting solution is required to save board space. The feed-through design eliminates the need for separate discrete components. Verify that the 1812 package dimensions fit the available layout area and that the 50 mA current handling capability exceeds the peak operational currents of the protected circuit lines.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability capacitors with flexible terminations. The 1812Y prefix indicates the 1812 case size and Y-series classification. As a feed-through device, it differs from standard MLCCs by integrating the termination structure into the conductive path, providing superior noise attenuation in compact form factors.

Replacement Considerations

Direct substitutes must match the 1812 feed-through footprint and 0.015 µF value. Standard MLCCs cannot replace this part due to the distinct three-pad configuration and integrated filtering function. Consult manufacturer catalogs for equivalent feed-through models with compatible voltage and current ratings.
