0805J0500333MXTE01

Overview

The Knowles Syfer 0805J0500333MXTE01 is a surface-mount feed-through capacitor with a capacitance of 0.033 µF and a rated voltage of 50V. It utilizes X7R dielectric material and features a 0805 (2012 metric) package size. The component includes an integrated 300 mA fuse function for circuit protection. It operates within a temperature range of -55°C to +125°C and offers ±20% tolerance.

Feature Summary

• Integrated pass-through fuse functionality providing overcurrent protection
• Feed-through architecture enabling direct signal path integration
• High-temperature stability utilizing X7R ceramic dielectric

Applications

• High-reliability electronic circuits requiring combined filtering and fusing
• Space-qualified applications demanding robust mechanical performance
• Systems necessitating compact EMI suppression with built-in protection

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm the presence of the integrated fuse feature, as standard MLCC variants lack this function. Ensure compatibility with RoHS3 standards and confirm moisture sensitivity level requirements for your assembly process before procurement.

Selection Notes

Select this component when board space constraints require combining decoupling, filtering, and overcurrent protection into a single footprint. Consider the 300 mA current rating carefully to ensure it aligns with the maximum allowable current for the protected trace without nuisance tripping during normal operation.

Part Context

This part belongs to the Knowles Syfer XT series, which specializes in high-reliability multilayer ceramic capacitors. The series is known for flexible termination materials that withstand significant board bending and thermal cycling, making it suitable for aerospace and harsh environment applications where standard components might fail.

Replacement Considerations

Direct substitutes must match the 0.033 µF value, 50V rating, 0805 package, and critically, the integrated 300 mA fuse feature. Standard 0805MLCCs cannot replace this part due to the missing fuse functionality. Verify equivalent ratings from other manufacturers offering similar feed-through fuse capacitors.
