1812Y0500822MJTE03

Overview

The Knowles Syfer 1812Y0500822MJTE03 is a multilayer ceramic capacitor (MLCC) in the FlexiCap series, designed for boardflex-sensitive applications. It features an X7R dielectric with a capacitance of 8.20 nF and a voltage rating of 500V DC. The component offers ±20% tolerance and operates within a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) surface-mount package, it incorporates soft termination technology and a nickel barrier electrode structure.

Feature Summary

• Soft termination design enhances reliability in boardflex-sensitive environments by absorbing mechanical stress.
• X2Y architecture provides integrated common-mode filtering capabilities within a single compact package.
• Nickel barrier electrode construction ensures robust performance under high-temperature conditions.

Applications

• Automotive electronics requiring AEC-Q200 compliance
• High-reliability circuits sensitive to board flexing
• Common-mode noise suppression in signal lines

Procurement Notes

Verify the complete part number including suffixes such as MJTE03, as these indicate specific termination and packaging configurations. Confirm RoHS3 compliance status and ensure the supplier provides official datasheets matching the manufacturer's documentation. Cross-reference the Mouser or DigiKey part numbers to validate authenticity before procurement.

Selection Notes

Select this component when high voltage handling and mechanical durability are required simultaneously. The X2Y functionality allows for space-saving designs by combining capacitance and filtering. Ensure the application environment stays within the specified -55°C to +125°C operating range to maintain dielectric stability.

Part Context

This component belongs to the Knowles Syfer FlexiCap family, which specializes in soft-termination MLCCs for automotive and industrial sectors. The 1812Y series denotes the 1812 case size with specific internal structures optimized for reliability. The Y500 code indicates the 500V DC voltage rating class within this product line.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 500V rating, 8.2nF value, and X2Y configuration. Verify that alternative parts also feature soft terminations if boardflex sensitivity is a critical design constraint. Check for equivalent nickel barrier constructions to ensure similar thermal performance.
