1206Y2000223MSTE03

Overview

The Knowles Syfer 1206Y2000223MSTE03 is a feed-through multilayer ceramic capacitor in a 1206 (3216 metric) package. It features a capacitance of 0.022 µF with a 20% tolerance and a DC voltage rating of 200 V. The component utilizes X7R dielectric material and includes an integrated nickel barrier structure. Designed for surface mount applications, it supports a maximum current of 50 mA and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated feed-through architecture providing internal shielding via a nickel barrier
• Flexible terminal construction designed to mitigate mechanical stress on the substrate
• High-reliability classification suitable for demanding operational environments

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Circuit boards sensitive to flex-induced mechanical failure
• Signal filtering and EMI suppression in high-density layouts

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm exact termination and barrier specifications. Ensure compatibility with automated pick-and-place equipment regarding the reel packaging format. Confirm that the 50 mA current rating aligns with the target circuit requirements before finalizing procurement orders.

Selection Notes

Select this component when board flex resistance and electromagnetic interference suppression are critical design constraints. The feed-through design offers superior shielding compared to standard MLCCs. Verify that the 1206 footprint dimensions fit the available PCB real estate and that the 200 VDC rating exceeds the peak operating voltage of the application.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability capacitors with flexible terminations. The series addresses reliability issues caused by mechanical stress on rigid ceramic bodies. The 1206Y prefix indicates the standardized case size used across the product line for consistent mounting profiles.

Replacement Considerations

Direct substitutes must match the 1206 feed-through form factor and nickel barrier construction. Standard MLCCs lack the integrated shielding and may not provide equivalent EMI performance. Verify that any alternative component maintains the same thermal stability and current handling capabilities.
