1812J0500822MJTE03

Overview

The Knowles Syfer 1812J0500822MJTE03 is a feed-through multilayer ceramic capacitor designed for surface-mount applications. It features an 8200 pF capacitance with a ±20% tolerance, rated for 50 VDC. The component utilizes a J-series dielectric and operates within a temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it integrates a three-terminal structure to provide enhanced high-frequency noise suppression capabilities compared to standard two-terminal capacitors.

Feature Summary

• Integrates a three-terminal feed-through architecture to minimize parasitic inductance and improve high-frequency filtering performance.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power supply input/output filtering
• Signal line decoupling in RF applications

Procurement Notes

Verify the specific suffix 'E03' against official manufacturer documentation to confirm terminal configuration and termination material specifications. Ensure compatibility with PCB pad layouts designed for three-terminal feed-through components rather than standard two-terminal footprints. Cross-reference datasheet revisions to confirm compliance with current environmental regulations.

Selection Notes

Select this component when low parasitic inductance is critical for high-speed signal integrity or power rail stability. The 1812 package offers a balance between capacitance density and thermal management. Confirm that the 50V rating exceeds the maximum circuit voltage including transients. Evaluate the need for feed-through topology versus standard MLCCs based on required attenuation characteristics at target frequencies.

Part Context

This part belongs to the Knowles Syfer J-series, which focuses on general-purpose high-reliability multilayer ceramic capacitors. The feed-through variant provides superior electromagnetic interference (EMI) suppression by utilizing the ground plane as a third terminal, effectively creating a coaxial-like structure within the SMD footprint.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify equivalent three-terminal feed-through capacitors from other manufacturers only if they match the 1812 footprint, 50V rating, and 8200pF value with compatible termination styles.
