1806Y0500274MJTE07

Overview

The Knowles Syfer 1806Y0500274MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1806 (4516 metric) case size with a capacitance of 270 nF, a voltage rating of 50 VDC, and an X7R dielectric material offering ±20% tolerance. The component utilizes FlexiCap technology with nickel barrier terminations to enhance mechanical robustness against board flexing. It operates within a temperature range of -55°C to +125°C and complies with RoHS standards.

Feature Summary

• FlexiCap technology provides enhanced resistance to mechanical stress and board flexing
• Nickel barrier termination structure ensures reliable soldering and durability
• X7R dielectric material maintains stable capacitance across wide temperature variations

Applications

• High-reliability electronic systems requiring mechanical stability
• Circuit boards subject to significant flexing or vibration
• General-purpose decoupling and filtering in SMD/SMT assemblies

Procurement Notes

Verify the specific ordering suffix to confirm package type and termination finish. Ensure compatibility with automated pick-and-place equipment regarding reel specifications. Confirm that the X7R dielectric characteristics meet the thermal requirements of the target application environment before finalizing procurement.

Selection Notes

Select this component when mechanical integrity under flexure is critical. The 1806 footprint offers higher capacitance density than smaller packages. Verify that the 50V rating exceeds the peak circuit voltage. Consider the nickel barrier termination if lead-free soldering processes are required.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors engineered for mechanical resilience. The series addresses common failure modes associated with standard MLCCs in flexible substrates or high-vibration environments, providing a robust solution for demanding industrial and commercial electronics.

Replacement Considerations

Direct substitutes must match the 1806 case size, 270nF capacitance, 50V rating, and X7R dielectric. Verify that alternative components also feature nickel barrier terminations if mechanical flexibility is a design constraint.
