1806Y0500123MJTE07

Overview

The Knowles Syfer 1806Y0500123MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 0.012 µF capacitance with a ±20% tolerance and a 50 VDC voltage rating. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1806 (4516 metric) package, it incorporates FlexiCap technology with soft terminals to enhance mechanical durability against board flexing stresses.

Feature Summary

• FlexiCap technology provides soft terminal construction to withstand mechanical stress from board flexing.
• X7R dielectric ensures reliable capacitance stability over a wide industrial temperature range.
• Designed specifically for high-reliability environments requiring robustness against physical deformation.

Applications

• Automotive electronics systems
• Boardflex sensitive circuit assemblies
• High-reliability industrial equipment

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal composition and packaging details. Ensure compatibility with automated pick-and-place equipment regarding the 1806 footprint dimensions. Confirm RoHS compliance status through current datasheets prior to integration into regulated supply chains.

Selection Notes

Select this component when design requirements demand resistance to mechanical strain in rigid-flex or flexible PCB layouts. The X7R dielectric offers a balance of capacitance density and thermal stability suitable for general-purpose decoupling in automotive contexts. Evaluate board stiffness to ensure the FlexiCap benefit is utilized effectively under operational loads.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors engineered for harsh mechanical environments. The series addresses common failure modes associated with standard MLCCs in applications subject to vibration and bending. It serves as a specialized solution within the broader portfolio of high-reliability passive components offered by the manufacturer.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 50V rating, 0.012µF value, and X7R dielectric. Verify that alternative components also feature soft or flexible terminations to maintain board flex resilience. Cross-reference AEC-Q200 qualification if automotive certification is required.
