1812J5000332MCTE03

Overview

The Knowles Syfer 1812J5000332MCTE03 is a feed-through multilayer ceramic capacitor with a capacitance of 3300 pF and a DC voltage rating of 200 V. It utilizes C0G (NP0) dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. The component features a 1812 (4532 metric) package size with a specialized three-pad surface mount configuration designed for high-frequency applications.

Feature Summary

• Integrated feed-through architecture providing inherent electromagnetic interference filtering capabilities within the component structure.
• Utilizes C0G (NP0) dielectric technology to maintain precise capacitance stability under varying thermal conditions.
• Designed with a specific three-pad mounting footprint to facilitate direct integration into high-frequency circuit layouts.

Applications

• High-frequency signal conditioning circuits requiring integrated filtering
• RF power amplifier output stages
• High-speed digital interface protection

Procurement Notes

Verify the specific three-pad footprint requirements against your PCB layout, as this feed-through variant differs from standard two-terminal MLCCs. Confirm that the 200 VDC rating aligns with your circuit's peak operating voltages. Ensure compatibility with the specified C0G dielectric characteristics for your frequency response needs. Check current handling specifications if used in power paths.

Selection Notes

Select this component when a combined decoupling and filtering function is required in a compact surface-mount form factor. The C0G dielectric is essential for applications demanding minimal capacitance variation with temperature or voltage. The 1812 case size offers a balance between current handling capability and board space efficiency compared to smaller packages.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, distinct from their general-purpose MLCC lines. Unlike standard capacitors, these integrate the filter element directly into the termination structure, reducing parasitic inductance. This specific model targets applications where space constraints and high-frequency performance necessitate an all-in-one solution.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Replacement requires matching the 1812 three-pad footprint, 3300 pF capacitance, 200 V rating, and C0G dielectric type. Verify mechanical compatibility with existing PCB pads before substitution.
