1812Y1000472MSTE03

Overview

The Knowles Syfer 1812Y1000472MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a capacitance of 4700 pF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The component utilizes X7R dielectric material and is housed in an 1812 (4532 metric) case size. It incorporates FlexiCap technology with nickel barrier and tin terminations, ensuring enhanced mechanical robustness against board flexing.

Feature Summary

• X2Y architecture providing integrated common-mode noise suppression
• FlexiCap soft termination design to withstand board flex stress
• AEC-Q200 qualification for automotive reliability standards

Applications

• Automotive electronics requiring EMI filtering
• Board-flex sensitive circuit designs
• High-reliability signal line protection

Procurement Notes

Verify the specific suffix MSTE03 to confirm the inclusion of FlexiCap soft terminations and AEC-Q200 automotive qualification. Ensure the X2Y configuration matches the required noise suppression topology for the target application. Confirm RoHS compliance status through official manufacturer documentation prior to integration.

Selection Notes

Select this component when integrated EMI filtering and mechanical durability are critical. The X2Y structure offers superior common-mode noise attenuation compared to standard capacitors. The FlexiCap feature is essential for assemblies subject to thermal cycling or mechanical strain that could damage rigid terminations.
