1812Y0500204MSTE03

Overview

The Knowles Syfer 1812Y0500204MSTE03 is a surface-mount X2Y capacitor featuring a 1812 (4532 metric) package. It provides a capacitance of 0.2 µF with a voltage rating of 50 VDC and a tolerance of ±20%. The component utilizes X7R dielectric material and is certified to the AEC-Q200 standard for automotive reliability. It incorporates FlexiCap technology with a nickel barrier to enhance mechanical durability against board flexing.

Feature Summary

• X2Y architecture integrates three terminals into a single SMD footprint to provide simultaneous common-mode and differential-mode noise suppression.
• FlexiCap construction with nickel barrier electrodes improves resistance to mechanical stress and board flexing during assembly and operation.
• AEC-Q200 qualification ensures compliance with rigorous automotive electronic component reliability standards.

Applications

• Automotive electronics requiring AEC-Q200 compliant components
• Power supply input filtering in vehicle systems
• Noise suppression on data lines in automotive infotainment units

Procurement Notes

Verify the complete part number including the suffix MSTE03 to ensure correct termination and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current availability as automotive-grade MLCCs may experience supply fluctuations. Ensure design compatibility with the specific 1812 footprint dimensions and terminal configuration.

Selection Notes

Select this component when space-constrained designs require combined common-mode and differential-mode filtering capabilities. The X2Y topology reduces the required PCB area compared to discrete filter arrangements. Verify that the 50V DC rating meets the circuit's maximum operating voltage requirements. Consider the FlexiCap feature if the application involves significant mechanical vibration or board flexing.

Part Context

This component belongs to the Knowles Syfer 1812Y series, which specializes in high-reliability X2Y capacitors. The series is designed for demanding environments where traditional multi-component filters are impractical due to size constraints. The 1812Y series offers integrated filtering solutions that simplify circuit design while maintaining robust performance in automotive and industrial applications.
