1812J0500823MJTE03

Overview

The Knowles Syfer 1812J0500823MJTE03 is a feed-through capacitor designed for surface mount applications. It features an X7R dielectric with a capacitance of 82 nF and a rated voltage of 50 VDC. The component operates within a temperature range of -55°C to +125°C and has a current rating of 50 mA. It utilizes a 1812 (4532 metric) package footprint.

Feature Summary

• Integrated feed-through architecture providing EMI suppression capabilities
• X2Y capacitor structure for enhanced noise filtering performance

Applications

• High-frequency signal line protection
• Power supply input filtering
• EMI suppression in sensitive electronic circuits

Procurement Notes

Verify the specific suffix MJTE03 against official datasheets to confirm the feed-through configuration and terminal arrangement. Ensure compatibility with PCB pad layouts designed for this unique three-terminal structure rather than standard two-terminal MLCC footprints.

Selection Notes

Select this component when integrated EMI filtering is required without occupying additional board space for discrete components. The feed-through design allows for direct inline placement on traces, simplifying layout compared to traditional shunt capacitors.

Part Context

This part belongs to the Knowles Syfer X2Y family, which combines three terminals into a single package to provide common-mode and differential-mode noise attenuation simultaneously. It differs from standard multilayer ceramic capacitors by its internal bridged electrode structure.

Replacement Considerations

Direct replacements are limited due to the specialized feed-through topology. Verify if alternative X2Y parts or discrete LC filters meet the same electrical constraints and physical footprint requirements.
