1206Y1000472MSTE03

Overview

The Knowles Syfer 1206Y1000472MSTE03 is a Surface Mount Multilayer Ceramic Capacitor (MLCC) in a 1206 (3216 metric) package. It features a capacitance of 4700 pF with a tolerance of ±20% and a DC voltage rating of 100 V. The component utilizes X7R dielectric material and holds AEC-Q200 qualification for automotive reliability. Key structural features include FlexiCap technology with a nickel barrier and an X2Y configuration, designed to enhance mechanical durability and electromagnetic interference suppression.

Feature Summary

• X2Y capacitor architecture providing integrated common-mode and differential-mode noise filtering within a single compact surface-mount footprint.
• FlexiCap construction with flexible terminations and a nickel barrier layer to improve resistance to board flex-induced cracking.
• AEC-Q200 qualified design ensuring compliance with rigorous automotive electronic component stress testing standards.

Applications

• Automotive electronics requiring AEC-Q200 certified components
• Board-flex sensitive circuit designs
• Electromagnetic interference (EMI) suppression in signal lines

Procurement Notes

Verify the complete part number including suffixes such as 'MSTE03' to ensure correct termination and barrier specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current supply chain availability as distribution may be restricted or limited depending on region and date.

Selection Notes

Select this component when high-reliability EMI filtering is required in space-constrained automotive applications. The X2Y topology offers superior noise reduction compared to standard capacitors. Ensure the PCB layout supports the specific pad geometry required for X2Y devices to realize intended performance benefits.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in robust MLCCs for demanding environments. The 1206Y series designation indicates the case size and voltage class. The MSTE03 suffix typically denotes specific termination materials and packaging configurations unique to this product line.

Replacement Considerations

Direct substitutes must match the 1206 case size, 100V rating, 4700pF capacitance, X7R dielectric, and X2Y topology. Verify that any replacement also possesses AEC-Q200 qualification if used in automotive contexts. Standard MLCCs without X2Y structure will not provide equivalent filtering performance.

FAQ

What is the significance of the X2Y configuration in this capacitor?

The X2Y configuration integrates three electrodes into one package, allowing it to filter both common-mode and differential-mode noise simultaneously, offering better EMI suppression than standard two-terminal capacitors.

Does this component meet automotive reliability standards?

Yes, the 1206Y1000472MSTE03 is AEC-Q200 qualified, meaning it has passed specific stress tests required for passive components in automotive electronic equipment.
