0805J0500821MCTE01

Overview

The Knowles Syfer 0805J0500821MCTE01 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features an 820 pF capacitance with a ±20% tolerance, rated for 50 VDC. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 0805 (2012 metric) package, it employs nickel barrier terminations with 100% tin plating. This specific variant is identified as an X2Y capacitor structure.

Feature Summary

• X2Y three-terminal architecture providing integrated common-mode filtering capabilities
• Nickel barrier termination system ensuring robust solderability and reliability
• High-temperature stability utilizing X7R dielectric characteristics

Applications

• Automotive electronics requiring AEC-Q200 qualification
• High-frequency signal line noise suppression
• Common-mode interference mitigation in sensitive circuits

Procurement Notes

Verify the exact suffix configuration during procurement, as variations such as MCT versus MAT may indicate differences in packaging or specific manufacturing lot attributes. Confirm RoHS compliance status and ensure the supplier provides official datasheets matching the full part number to avoid discrepancies in terminal materials or internal structure.

Selection Notes

Select this component when space-constrained designs require combined capacitance and EMI filtering functions. The X2Y topology offers superior performance compared to discrete capacitors in high-noise environments. Ensure the 50V rating aligns with circuit voltage peaks and verify that the 0805 footprint accommodates the specific height requirements of the X2Y structure.

Part Context

This component belongs to the Knowles Syfer 0805J series of general-purpose MLCCs. The 'J' indicates the 0805 case size, while the numerical sequence defines the electrical parameters. The inclusion of 'TE' in the model number specifically denotes the X2Y three-terminal construction, distinguishing it from standard two-terminal capacitors within the same capacitance and voltage class.

Replacement Considerations

Direct substitutes include other X2Y capacitors from Knowles Syfer with identical 820pF/50V/X7R specifications in the 0805 package. Cross-brand replacements must match the three-terminal pinout and equivalent impedance characteristics at target frequencies.
