1812Y1000124MSTE03

Overview

The Knowles Syfer 1812Y1000124MSTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 0.12 µF with a voltage rating of 100 VDC and a current rating of 50 mA. The component utilizes an X7R dielectric material housed in a standard 1812 (4532 metric) package. This device incorporates a three-pad configuration to facilitate integrated filtering capabilities within compact circuit layouts.

Feature Summary

• Integrates feed-through architecture for combined decoupling and filtering functions
• Utilizes X7R dielectric for stable capacitance performance across operating temperatures
• Features a specialized three-pad footprint design for enhanced board integration

Applications

• High-frequency signal line filtering
• Power supply decoupling in sensitive circuits
• Automotive electronics requiring AEC-Q200 compliance

Procurement Notes

Verify the specific three-pad footprint requirements against your PCB layout, as this component differs from standard two-terminal MLCCs. Confirm that the 50 mA current rating meets your application's peak load demands. Ensure compatibility with the 1812 package dimensions during the assembly process planning phase.

Selection Notes

Select this component when space constraints require integrated filtering without additional discrete inductors or capacitors. The X7R dielectric offers a balance of capacitance density and temperature stability suitable for general-purpose applications. Consider the three-terminal topology if electromagnetic interference suppression is critical in the design.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which emphasizes reliability in automotive and industrial sectors. The 'Y' prefix typically denotes the 1812 case size, while the suffix indicates the specific termination and packaging configuration. It represents a specialized variant within the broader MLCC portfolio focused on high-reliability filtering solutions.

Replacement Considerations

Direct substitutes must match the 0.12 µF capacitance, 100 V rating, and specifically the feed-through three-terminal structure. Standard two-terminal MLCCs are not functionally equivalent due to the lack of integrated filtering capability. Verify mechanical footprint compatibility before considering alternative manufacturers.
