1206Y2000183MSTE03

Overview

The Knowles Syfer 1206Y2000183MSTE03 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features an X7R dielectric with a capacitance of 18 nF and a DC voltage rating of 200 V. The component utilizes a 1206 (3216 metric) case size and offers a tolerance of ±20%. It incorporates FlexiCap™ flexible terminations to enhance mechanical durability and includes a nickel barrier structure. The device is AEC-Q200 qualified, ensuring suitability for automotive applications.

Feature Summary

• FlexiCap flexible termination technology reduces stress on the capacitor body and PCB pads during thermal cycling or board flexing.
• Nickel barrier construction provides enhanced protection against electrode migration and improves long-term reliability.
• AEC-Q200 qualification ensures compliance with strict automotive electronic component standards.

Applications

• Automotive electronics systems requiring AEC-Q200 certified components
• High-reliability circuit boards sensitive to mechanical stress
• General-purpose decoupling and filtering in industrial equipment

Procurement Notes

Verify the specific suffix MSTE03 to confirm the inclusion of the nickel barrier and FlexiCap features, as standard variants may differ. Confirm RoHS compliance status through the official datasheet before integration. Check current supply chain availability as distribution channels may vary by region. Ensure storage conditions align with manufacturer guidelines for moisture-sensitive devices.

Selection Notes

Select this component when high mechanical robustness is required alongside stable X7R performance at 200 VDC. The 1206 footprint balances capacitance density with physical durability. Consider the nickel barrier feature if operating environments pose risks of electrode migration. Verify that the ±20% tolerance meets the circuit design requirements for noise filtering or decoupling.

Part Context

This part belongs to the Knowles Syfer 1206Y series of high-reliability MLCCs. The series is engineered for demanding environments where standard capacitors might fail due to mechanical stress. The Y-series designation typically indicates specific termination and barrier technologies tailored for automotive and industrial sectors.

Replacement Considerations

Direct substitutes must match the 1206 package, 200V rating, 18nF capacitance, X7R dielectric, and AEC-Q200 qualification. Verify that any alternative also includes FlexiCap and nickel barrier features if mechanical reliability is critical. Cross-reference pin compatibility and electrical characteristics carefully.
