1812J5000122MCTE03

Overview

The Knowles Syfer 1812J5000122MCTE03 is a feed-through multilayer ceramic capacitor designed for surface mount technology. It features a capacitance of 1200 pF with a voltage rating of 500 VDC and a tolerance of ±20%. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a compact 1812 (4532 metric) package, it supports a maximum current of 50 mA and includes three pad connections for secure PCB mounting.

Feature Summary

• Integrated feed-through architecture combining filtering and decoupling functions within a single surface-mount component.
• Utilizes C0G (NP0) dielectric material to provide high stability and minimal capacitance variation over temperature changes.
• Features a flexible terminal design compatible with standard SMD/SMT assembly processes.

Applications

• High-frequency signal filtering in communication equipment
• Power supply decoupling in automotive electronics
• EMI suppression in industrial control systems

Procurement Notes

Verify the specific suffix E03 against official datasheets to confirm the feed-through configuration and terminal structure. Ensure compatibility with the required 50 mA current rating and 500 VDC operating conditions. Confirm RoHS compliance status through manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when space constraints require a combined filter and capacitor solution in the 1812 footprint. The C0G dielectric is suitable for applications demanding precise capacitance stability. Evaluate the 50 mA current handling capability against circuit requirements to ensure reliable operation under load.
