0805J0500333MJTE07

Overview

The Knowles Syfer 0805J0500333MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a capacitance of 0.033 µF with a tolerance of ±20% and a rated DC voltage of 50V. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 0805 (2012 metric) package, it employs a nickel barrier electrode structure terminated with 100% tin plating. This specific variant is configured as an X2Y capacitor, providing integrated EMI filtering capabilities within the passive component footprint.

Feature Summary

• X2Y architecture integrates three-terminal EMI filtering functionality directly into the capacitor structure.
• Nickel barrier electrode construction enhances reliability under harsh environmental conditions.
• High-temperature stability provided by X7R dielectric suitable for demanding thermal environments.

Applications

• High-reliability electronic assemblies requiring robust EMI suppression
• Automotive grade components compliant with AEC-Q200 standards
• General purpose MLCC applications in surface mount technology

Procurement Notes

Verify the exact suffix configuration against official manufacturer documentation to ensure correct termination and internal structure. Confirm RoHS compliance status and REACH registration details prior to integration. Cross-reference the full part number with authorized distributor catalogs to validate current availability and lead times. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the datasheet.

Selection Notes

Select this component when a compact solution combining capacitance and EMI filtering is required. The X2Y topology offers superior noise suppression compared to standard two-terminal capacitors in limited space. Consider the 0805 footprint constraints and verify that the 50V rating meets the circuit's maximum operating voltage. Evaluate the ±20% tolerance against circuit sensitivity requirements for decoupling or filtering roles.
