1806Y0250332MJTE07

Overview

The Knowles Syfer 1806Y0250332MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1806 case size with a capacitance of 3300 pF and a DC 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 operates within a temperature range of -55°C to +125°C. The device incorporates FlexiCap technology with nickel barrier end terminations to enhance mechanical robustness against board flexing.

Feature Summary

• FlexiCap flexible end termination technology reduces stress on the ceramic body during PCB bending or thermal cycling.
• Nickel barrier layer provides enhanced solderability and protects against corrosion in harsh environments.
• C0G/NP0 dielectric ensures minimal capacitance change over temperature and voltage variations.

Applications

• High-reliability aerospace and defense electronic systems
• Automotive electronics requiring resistance to board flexing
• Industrial control circuits demanding long-term stability

Procurement Notes

Verify the specific ordering suffix to confirm the presence of FlexiCap and nickel barrier features, as standard variants may differ. Ensure compatibility with RoHS 3 compliance requirements if applicable to your region. Confirm that the 1806 package dimensions align with your PCB footprint constraints. Check for any specific environmental certifications required for your industry sector before finalizing procurement.

Selection Notes

Select this component when mechanical flexibility is critical to prevent cracking in rigid ceramic capacitors. The C0G dielectric is suitable for timing and filtering applications where low loss and high stability are required. Consider the 25V rating relative to circuit operating voltages to ensure adequate derating margins. Evaluate the 1806 size against available board space and thermal management needs.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs with compliant end terminations. The series addresses common failure modes associated with mechanical stress in traditional rigid-termination capacitors. It is categorized under general-purpose ceramic capacitors but is distinguished by its enhanced mechanical durability features compared to standard commercial-grade parts.

Replacement Considerations

Direct substitutes must match the 1806 case size, 3300pF capacitance, 25V rating, and C0G dielectric. Verify that alternative components also feature FlexiCap or equivalent flexible termination technology to maintain mechanical reliability. Cross-reference nickel barrier specifications to ensure identical corrosion resistance and soldering characteristics.
