1806Y0250563MXTE07

Overview

The Knowles Syfer 1806Y0250563MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features an X7R dielectric material and operates within a temperature range of -55°C to +125°C. The component has a capacitance of 0.056 µF with a tolerance of ±5% and a DC voltage rating of 25V. Packaged in a 1806 (4516 metric) case size, it utilizes FlexiCap technology with nickel barrier end terminations to enhance mechanical robustness against board flexure.

Feature Summary

• FlexiCap flexible end termination technology reduces stress on the ceramic body during PCB bending
• Nickel barrier layer prevents solder wicking and enhances long-term reliability
• X7R dielectric provides stable capacitance performance across the specified operating temperature range

Applications

• High-reliability general-purpose electronics
• Board-flex sensitive circuit designs
• Automotive grade components requiring AEC-Q200 compliance

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging format matches production requirements. Confirm that the FlexiCap variant aligns with mechanical constraints regarding board flexibility. Cross-reference the manufacturer part number with official datasheets to validate terminal configuration and environmental compliance status before finalizing procurement orders.

Selection Notes

Select this component when mechanical integrity under board flexure is critical. The FlexiCap design mitigates cracking risks associated with rigid terminations. Ensure the 1806 footprint accommodates the physical dimensions. Verify that the X7R temperature coefficient meets the thermal stability requirements of the target application environment.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors with flexible terminations. The series addresses reliability issues in surface-mount devices subjected to mechanical stress. The 1806Y prefix indicates the case size and voltage class within the broader MLCC portfolio.

Replacement Considerations

Consider parts from the same FlexiCap family with identical case sizes and voltage ratings. Verify compatibility of the nickel barrier termination structure. Ensure substitute components maintain equivalent AEC-Q200 qualification if automotive reliability is required.
