1806J0500220MCTE01

Overview

The Knowles Syfer 1806J0500220MCTE01 is a surface-mount multilayer ceramic capacitor designed as a three-terminal EMI filter. It features a C0G (NP0) dielectric with a capacitance of 22 pF and a tolerance of ±20%. The component has a DC voltage rating of 50 VDC and operates within a temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package, it utilizes nickel barrier terminations with 100% tin plating for reliable soldering.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference suppression compared to standard two-terminal capacitors.
• C0G (NP0) dielectric ensures stable capacitance performance across varying temperatures and voltages.
• Nickel barrier termination structure offers robust mechanical strength and resistance to soldering thermal stress.

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output noise suppression in industrial control systems
• EMI mitigation in automotive electronic modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm termination material and packaging configuration. Ensure the selected variant matches the required 1806 footprint and three-terminal topology for proper PCB layout integration.

Selection Notes

Select this component when low-loss, high-stability filtering is required for sensitive analog or RF circuits. The C0G dielectric minimizes microphonic effects and voltage coefficient changes, making it suitable for precision applications where capacitance drift must be minimized under operational conditions.

Part Context

This part belongs to the Knowles Syfer J-series of surface-mount EMI filters. These components are engineered for high-reliability environments, combining the compact form factor of MLCCs with the superior attenuation characteristics of feedthrough capacitor designs.

Replacement Considerations

Direct substitutes require matching the 1806 package, 3-terminal configuration, 50V rating, and 22pF C0G specification. Verify compatibility with existing PCB land patterns and thermal profiles during reflow soldering processes.
