1812Y2000822MSTE03

Overview

The Knowles Syfer 1812Y2000822MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in the FlexiCap series. It features an X7R dielectric with a nominal capacitance of 8200 pF and a voltage rating of 200 VDC. The component utilizes a 1812 (4532 metric) package size, measuring 4.50 mm in length and 3.20 mm in width. It offers a tolerance of ±20% and operates within a temperature range of -55°C to +125°C. The device incorporates soft termination technology with a nickel barrier for enhanced mechanical reliability.

Feature Summary

• Soft termination design with nickel barrier to withstand board flex stress
• X7R dielectric material providing stable capacitance across operating temperatures
• AEC-Q200 qualification for automotive electronics applications

Applications

• Automotive electronic systems requiring high reliability
• Printed circuit boards susceptible to mechanical flexing
• General-purpose decoupling and filtering in automotive environments

Procurement Notes

Verify the specific suffix MSTE03 to confirm the presence of the nickel barrier and soft termination structure, as standard variants may differ. Ensure the procurement channel provides valid traceability documentation required for automotive-grade components. Confirm RoHS compliance status matches current regulatory requirements before finalizing orders.

Selection Notes

Select this component when board flex resistance is critical due to chassis mounting or vibration. The 200V rating suits intermediate voltage rails in automotive power distribution. Consider the 1812 footprint constraints against available PCB real estate. The X7R characteristic is suitable for general filtering where precise stability is less critical than cost and robustness.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, designed specifically for flexible substrates and mechanically stressed environments. Unlike standard rigid MLCCs, these devices integrate compliant end terminations to prevent cracking during assembly or operation. The 1812Y prefix indicates the series and case size, while the MSTE03 suffix defines the specific termination and barrier configuration.
