1206J2000392MJTE07

Overview

The Knowles Syfer 1206J2000392MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a C0G/NP0 dielectric material, ensuring stable capacitance characteristics across varying temperatures and voltages. The component offers a nominal capacitance of 3900 pF with a tolerance of ±5%. It is rated for a maximum working voltage of 200 VDC and operates within a temperature range of -55°C to +125°C. The physical dimensions conform to the standard 1206 (3216 metric) package size, measuring 3.20 mm in length, 1.60 mm in width, and a maximum height of 1.30 mm. The termination system utilizes a nickel barrier structure with 100% tin plating, providing robust solderability and corrosion resistance suitable for automated assembly processes.

Feature Summary

• Utilizes C0G/NP0 dielectric technology for minimal capacitance variation over temperature and bias conditions.
• Features a nickel barrier end termination structure combined with 100% tin plating for enhanced reliability.
• Designed for high-reliability environments requiring stable performance under thermal stress.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm termination and packaging details. Ensure that the procurement channel provides traceable documentation regarding RoHS compliance and material composition. Cross-reference the part number with official distributor catalogs to confirm availability status and lead times prior to finalizing supply agreements.

Selection Notes

Select this component when circuit design requires a Class 1 ceramic capacitor with high voltage stability in a compact 1206 footprint. The C0G dielectric is appropriate for applications where capacitance must remain constant despite changes in operating temperature or applied DC bias. Consider the 200V rating relative to peak transient voltages in the target application to ensure adequate safety margins.

Part Context

This component belongs to the Knowles Syfer general-purpose MLCC series, which focuses on high-reliability ceramic capacitors for industrial and commercial electronics. The '1206' prefix indicates the standardized case size, while the 'J' designation typically corresponds to the voltage rating class within the manufacturer's coding system. This series supports various capacitance values and tolerances tailored for demanding electronic environments.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 3900 pF capacitance, ±5% tolerance, 200V rating, and C0G dielectric type. Verify that alternative manufacturers offer compatible nickel-barrier terminations if solder joint integrity is critical. Ensure replacement parts meet the same -55°C to +125°C operating temperature range.
