1806Y0250564MXTE07

Overview

The Knowles Syfer 1806Y0250564MXTE07 is a Surface Mount Device (SMD) Multi-Layer Ceramic Capacitor (MLCC) designed for high-reliability applications. It features a 1806 case size with a capacitance of 560 nF and a DC voltage rating of 25 VDC. The component utilizes X7R dielectric material, providing stable performance across a wide temperature range from -55°C to +125°C. 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 and PCB pads during board flexing.
• Nickel barrier layer provides robust solderability and protects against corrosion in harsh environments.
• X7R dielectric ensures consistent capacitance stability over the specified operating temperature range.

Applications

• Board-flex sensitive electronic assemblies
• High-reliability industrial equipment
• Automotive electronics requiring vibration resistance

Procurement Notes

Verify the specific ordering suffix to confirm the presence of the FlexiCap/Nickel Barrier feature set, as standard variants may differ. Ensure compatibility with RoHS3 compliance requirements if mandated by your project specifications. Cross-reference the manufacturer's latest datasheet to confirm current production status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when board flex sensitivity is a primary concern due to its specialized flexible termination structure. The 1806 package allows for higher capacitance density compared to smaller footprints while maintaining a 25V rating suitable for low-voltage signal and power filtering. Verify that the X7R temperature characteristics align with the thermal environment of the target application.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs engineered for mechanical resilience. The series addresses common failure modes associated with rigid terminations in dynamic or stressed mounting conditions. It represents a solution for applications where standard ceramic capacitors might suffer from cracking under mechanical strain.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 560nF/25V/X7R electrical ratings, and specifically the FlexiCap/Nickel Barrier termination style to maintain mechanical integrity. Generic X7R replacements without flexible terminations are not equivalent for flex-sensitive designs.
