1806Y0250393MJTE07

Overview

The Knowles Syfer 1806Y0250393MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1806 (4520 metric) case size with a capacitance of 39,000 pF and a voltage rating of 25 VDC. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across varying temperatures. It offers a tolerance of ±20% and incorporates FlexiCap technology with nickel barrier end terminations to enhance mechanical durability.

Feature Summary

• FlexiCap flexible end termination design reduces stress on the capacitor body during board flexing
• Nickel barrier layer prevents electrode migration and enhances solderability reliability
• C0G/NP0 dielectric provides minimal capacitance change over temperature and voltage variations

Applications

• High-reliability aerospace and defense circuits
• Board-flex sensitive automotive electronics
• Precision timing and filtering in communication equipment

Procurement Notes

Verify the specific suffix 'MJTE07' against the manufacturer datasheet to confirm the exact termination plating and reel packaging configuration. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference the Mouser number 843-1806Y0250393MJTE07 for accurate distributor identification and current availability status.

Selection Notes

Select this component when board flex resistance is critical due to its flexible termination structure. The C0G dielectric makes it suitable for applications requiring stable capacitance under thermal cycling. Compare against standard MLCCs if mechanical robustness outweighs cost constraints. Verify that the 25V rating meets the circuit's peak voltage requirements including derating factors.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in mechanically robust ceramic capacitors. The 1806Y prefix indicates the 1806 case size and Y-series characteristics. These components are engineered to withstand mechanical shock and vibration better than standard MLCCs, making them preferred for ruggedized environments where standard ceramics might crack.

Replacement Considerations

Direct substitutes include other FlexiCap parts with identical case sizes and ratings, such as 1806Y0500393MJTE07 for higher voltage tolerance. Verify that any replacement maintains the nickel barrier termination and C0G dielectric properties to ensure equivalent mechanical and electrical performance.
