1812J0500154MJTE03

Overview

The Knowles Syfer 1812J0500154MJTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 150 nF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range from -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it incorporates a nickel barrier termination system with 100% tin plating. This part functions as an X2Y capacitor, providing integrated filtering capabilities within a compact form factor suitable for high-density circuit board layouts.

Feature Summary

• Integrates feed-through architecture with X2Y topology for enhanced electromagnetic interference suppression
• Utilizes nickel barrier termination structure combined with 100% tin plating for reliable soldering
• Employs X7R dielectric material to maintain capacitance stability under varying thermal conditions

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in automotive electronics
• Electromagnetic compatibility (EMC) mitigation in sensitive digital circuits

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal materials and dielectric type. Ensure design compatibility with the 1812 footprint dimensions. Confirm that the X7R characteristics align with the thermal requirements of the target application environment before finalizing procurement specifications.

Selection Notes

Select this component when integrated EMI filtering is required without occupying additional board space. The X2Y configuration offers superior noise reduction compared to standard capacitors. Consider the nickel barrier terminations for applications requiring robust solder joint integrity. Evaluate the 50V rating against peak transient voltages to ensure adequate safety margins in the operational circuit.

Part Context

This component belongs to the Knowles Syfer MLCC portfolio, specifically engineered for surface mount applications. The 1812J series designation indicates a Class 1 or specialized construction variant within the broader capacitor family. As a feed-through device, it differs from conventional two-terminal capacitors by routing signals through the center electrode, thereby minimizing parasitic inductance and improving high-frequency performance.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameters if considering alternative manufacturers. Ensure any replacement maintains the X2Y functionality and nickel barrier termination specifications.
