1812J2000222MCTE03

Overview

The Knowles Syfer 1812J2000222MCTE03 is a feed-through capacitor designed for surface mount technology. It features a capacitance of 2200 pF with a voltage rating of 200 VDC and a current rating of 50 mA. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) package, it provides effective electromagnetic interference suppression in compact electronic designs.

Feature Summary

• Integrates feed-through architecture for direct signal line filtering
• Utilizes C0G/NP0 dielectric for high stability and low loss
• Supports 50 mA continuous current handling capability
• Designed for surface mount assembly on standard PCB pads

Applications

• RF circuit impedance matching and filtering
• High-frequency signal line noise suppression
• Power supply input/output decoupling
• Electromagnetic interference mitigation in sensitive electronics

Procurement Notes

Verify the specific E03 suffix against official datasheets to confirm terminal configuration and pinout compatibility. Ensure design reviews account for the 50 mA current limit during thermal analysis. Cross-reference package dimensions with PCB footprint libraries to guarantee accurate placement and soldering integrity.

Selection Notes

Select this component when integrated feed-through functionality is required within a standard 1812 footprint. The C0G dielectric ensures minimal capacitance variation over temperature and voltage. Evaluate the 50 mA current rating against peak operational loads to prevent device degradation or failure under sustained stress conditions.

Part Context

This part belongs to the Knowles Syfer 1812J series of multilayer ceramic capacitors. Unlike standard MLCCs, this variant incorporates a feed-through structure, combining capacitance with conductive pathways. It serves as a specialized solution for applications demanding both energy storage and signal integrity management in constrained spaces.

Replacement Considerations

Direct substitutes require identical feed-through topology and 50 mA current ratings. Verify that alternative components match the 2200 pF capacitance and 200 VDC rating while maintaining the 1812 package dimensions for mechanical compatibility.
