1206Y2000472MSTE03

Overview

The Knowles Syfer 1206Y2000472MSTE03 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 4700 pF and a voltage rating of 200 VDC. The component operates within a temperature range of -55°C to +125°C and utilizes an X7R dielectric material with a ±20% tolerance. Packaged in a standard 1206 (3216 metric) footprint, it integrates a flexible terminal structure to enhance mechanical reliability under board flex conditions.

Feature Summary

• Integrates feed-through architecture for effective electromagnetic interference filtering
• Utilizes flexible terminal technology to withstand mechanical stress from board flexing
• Constructed with X7R ceramic dielectric for stable performance across operating temperatures

Applications

• High-reliability automotive electronics requiring AEC-Q200 compliance
• Circuit boards susceptible to mechanical deformation or vibration
• Signal lines requiring integrated decoupling and noise suppression

Procurement Notes

Verify the specific suffix STE03 against official datasheets to confirm the presence of the nickel barrier and FlexiCap terminals. Ensure the selected variant matches the required 200V DC rating and 4700 pF capacitance for the target application. Confirm RoHS compliance status through manufacturer documentation before integration.

Selection Notes

Select this component when board flex resistance is critical alongside EMI filtering. The 1206 package offers a balance between current handling and space constraints. Verify that the X7R dielectric characteristics align with the circuit's stability requirements at the intended operating frequencies and temperatures.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors with soft terminations. The series targets applications where standard rigid terminations might fail due to mechanical strain. The 1206Y prefix indicates the standard 1206 case size used across various voltage and capacitance ratings within the product line.
