1812Y0500473MJTE03

Overview

The Knowles Syfer 1812Y0500473MJTE03 is a multilayer ceramic capacitor (MLCC) in an 1812 surface-mount package. It features a capacitance of 47 nF with a ±20% tolerance and a DC voltage rating of 50 V. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Key structural attributes include FlexiCap soft termination technology and a nickel barrier layer to enhance mechanical reliability. This part is classified as an X2Y capacitor structure and holds AEC-Q200 automotive qualification.

Feature Summary

• X2Y internal architecture providing integrated filtering capabilities
• FlexiCap soft termination design for board flex sensitivity
• Nickel barrier electrode construction for enhanced durability
• AEC-Q200 qualified for automotive electronic applications

Applications

• Automotive electronics requiring board flex resistance
• Circuit protection against transient voltage events
• High-reliability signal conditioning networks

Procurement Notes

Verify the complete part number including suffixes to ensure correct termination and barrier specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet revisions to validate electrical characteristics match current production standards. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the handling guidelines.

Selection Notes

Select this component when circuit designs demand combined decoupling and transient suppression in a single footprint. The X2Y topology offers superior noise attenuation compared to standard capacitors. Evaluate mechanical stress profiles on the PCB to determine if soft termination benefits outweigh potential cost differences. Verify that the X7R dielectric behavior aligns with the specific frequency and temperature stability requirements of the application.

Part Context

This device belongs to the Knowles Syfer 1812Y series, which specializes in high-reliability automotive-grade capacitors. The series integrates advanced termination technologies to address common failure modes in flexible printed circuit boards. It represents a convergence of passive filtering and structural resilience within the standard 1812 industry footprint.

Replacement Considerations

Direct substitutes must match the X2Y configuration and FlexiCap termination. Standard MLCCs lack the integrated filtering and mechanical protection features. Verify pinout compatibility and thermal characteristics before considering alternative manufacturers.
