1806J0500122MCTE07

Overview

The Knowles Syfer 1806J0500122MCTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1200 pF capacitance with a ±20% tolerance, rated for 50 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across a wide temperature range from -55°C to +125°C. Housed in an 1806 (4532 metric) package, it offers standard SMD/SMT termination and complies with RoHS standards.

Feature Summary

• Utilizes C0G (NP0) dielectric for minimal capacitance variation over temperature and voltage changes.
• Engineered for high-reliability environments requiring stable electrical characteristics.
• Supports surface-mount technology for automated assembly processes.

Applications

• High-frequency signal coupling and decoupling circuits
• Precision timing and oscillator circuits
• RF filtering and impedance matching networks

Procurement Notes

Verify the specific suffix MCTE07 against official datasheets to confirm terminal plating and packaging details. Ensure compatibility with reflow soldering profiles specified by the manufacturer. Confirm RoHS compliance status for your region's regulatory requirements before finalizing procurement.

Selection Notes

Select this component when circuit stability under varying thermal conditions is critical. The C0G dielectric ensures low loss and high Q-factor suitable for RF applications. Verify that the 1806 footprint matches the PCB layout constraints and that the 50V rating exceeds the peak operating voltage of the application.

Part Context

This part belongs to the Knowles Syfer high-reliability MLCC series, which focuses on robust construction for demanding electronic environments. The 1806J prefix indicates the case size and voltage class within the broader Syfer portfolio, distinguishing it from general-purpose capacitors used in consumer electronics.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 1200pF value, 50V rating, and C0G dielectric. Verify terminal configuration and moisture sensitivity levels. Cross-reference with other manufacturers' C0G MLCCs only if mechanical and electrical parameters are identical.
