1206Y0500183MXTE07

Overview

The Knowles Syfer 1206Y0500183MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1206 case size with a capacitance of 18 nF and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material, providing a tolerance of ±20%. It incorporates FlexiCap termination technology with a nickel barrier and tin plating to enhance mechanical durability against board flexing and thermal cycling.

Feature Summary

• FlexiCap flexible termination technology accommodates significant PCB bending and thermal stress without cracking
• Nickel barrier electrode structure provides enhanced reliability compared to standard palladium-silver terminations
• X7R dielectric offers stable capacitance performance across a wide operating temperature range

Applications

• Automotive electronics requiring AEC-Q200 qualification compliance
• High-reliability industrial control systems subject to mechanical vibration
• Telecommunications infrastructure equipment demanding long-term stability

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm termination material and packaging details. Ensure compatibility with automated pick-and-place assembly processes. Confirm RoHS compliance status through official environmental declarations before integration into regulated supply chains.

Selection Notes

Select this component when mechanical robustness against substrate warpage is critical. The FlexiCap design reduces failure rates in rigid PCBs during reflow or operation. Compare electrical parameters such as capacitance drift and insulation resistance against alternative MLCC families to ensure circuit requirements are met.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in mechanically resilient ceramic capacitors. The series addresses common failure modes associated with standard MLCCs in rigid mounting environments. It represents a specialized solution for sectors where mechanical integrity is as important as electrical performance.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 50V rating, 18nF value, and X7R dielectric. Verify that replacement parts also feature flexible terminations if mechanical stress is a design constraint. Cross-reference pinout and polarity if applicable, though MLCCs are typically non-polarized.
