1812J2000273MXTE03

Overview

The Knowles Syfer 1812J2000273MXTE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring an X7R dielectric and a capacitance of 27 nF. It operates at a DC voltage rating of 200 V with a tolerance of ±20%. The component utilizes a 1812 (4532 metric) case size and incorporates X2Y architecture for enhanced electromagnetic interference suppression. Termination consists of nickel barrier plating with 100% tin, ensuring compatibility with standard soldering processes.

Feature Summary

• X2Y architecture provides integrated common-mode filtering within the passive component structure
• Nickel barrier termination with 100% tin finish ensures reliable solderability and corrosion resistance
• X7R dielectric offers stable capacitance performance across a wide operating temperature range

Applications

• Electromagnetic interference (EMI) suppression in high-speed digital circuits
• Common-mode noise filtering in data transmission lines
• Power supply input/output decoupling in sensitive electronic equipment

Procurement Notes

Verify the complete part number including the suffix to confirm specific termination and packaging configurations. Ensure compatibility with existing PCB footprint designs due to the specific terminal arrangement inherent to X2Y components. Cross-reference manufacturer documentation for handling precautions related to the ceramic body and metallization layers during assembly.

Selection Notes

Select this component when integrated EMI filtering is required without occupying additional board space for discrete filters. The X2Y design simplifies circuit topology by combining capacitive coupling paths. Evaluate thermal stability requirements against the X7R characteristics and ensure the 200 VDC rating exceeds peak circuit voltages with adequate margin.

Part Context

This component belongs to the Knowles Syfer MLCC portfolio, specifically utilizing proprietary X2Y technology. The series integrates three internal electrodes to create two independent capacitive paths between terminals, enabling effective noise suppression in compact surface-mount packages suitable for modern high-density electronics.

Replacement Considerations

Direct substitutes must match the X2Y pin configuration and electrical ratings. Verify that alternative components maintain the same terminal layout to prevent PCB redesign. Standard MLCCs cannot replace this part due to the unique internal electrode structure.
