0805Y0500333MXTE07

Overview

The Knowles Syfer 0805Y0500333MXTE07 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a 0805 (2012 metric) case size with a capacitance of 33 nF and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material, providing a capacitance tolerance of ±20%. It operates within a temperature range of -55°C to +125°C. Key structural features include flexible (soft) terminals and a nickel barrier with 100% tin plating on the three-terminal configuration.

Feature Summary

• Incorporates flexible terminal technology to enhance mechanical durability in board-flex sensitive applications.
• Features a three-terminal EMI filter design utilizing a nickel barrier and 100% tin termination system.

Applications

• Board-flex sensitive electronic assemblies
• EMI filtering circuits requiring three-terminal configurations
• High reliability surface-mount applications

Procurement Notes

Verify the specific suffix MXTE07 against official datasheets to confirm the three-terminal EMI filter construction and nickel barrier termination. Standard two-terminal MLCCs lack these features. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) requirements for your assembly process. Ensure the supplier provides traceable documentation matching the manufacturer's part identification.

Selection Notes

Select this component when board flex resistance is critical due to its soft terminal construction. The three-terminal architecture offers superior high-frequency noise attenuation compared to standard two-terminal capacitors. Verify that the 50V DC rating and 33 nF capacitance meet circuit requirements. Consider the 0805 footprint constraints and ensure compatibility with automated pick-and-place equipment.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability MLCCs with flexible terminations. The series targets applications prone to mechanical stress from PCB bending or thermal cycling. The 0805Y prefix indicates the 0805 case size and general product family characteristics within the manufacturer's portfolio.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-referencing requires verifying identical electrical parameters, three-terminal EMI filter structure, and flexible terminal specifications.
