1206Y0500683MSTE03

Overview

The Knowles Syfer 1206Y0500683MSTE03 is a surface-mount feed-through capacitor designed for high-reliability applications. It features a 1206 (3216 metric) package with a capacitance of 0.068 µF and a DC voltage rating of 50 V. The component utilizes X7R dielectric material and offers a pass current rating of 50 mA. It operates within a temperature range of -55°C to +125°C and employs a three-pad mounting configuration.

Feature Summary

• Integrated feed-through architecture providing direct signal path conduction through the capacitor body.
• Flexible terminal design engineered to mitigate mechanical stress on board-flex sensitive substrates.
• Nickel barrier construction ensures robust solderability and long-term environmental stability.

Applications

• High-frequency signal filtering in automotive electronic control units
• EMI suppression in board-flex sensitive mobile device assemblies
• Power line conditioning for sensitive RF components

Procurement Notes

Verify the specific MSTE suffix against official datasheets to confirm the three-pad feed-through topology, as standard MLCCs differ significantly. Confirm RoHS compliance status and AEC-Q200 qualification requirements with the manufacturer prior to integration into safety-critical systems.

Selection Notes

Select this component when simultaneous power delivery and signal filtering are required in a single footprint. The flexible terminals make it suitable for rigid-flex PCBs where standard rigid terminations might fail under thermal cycling or mechanical strain.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability multilayer ceramic capacitors. The series is distinguished by its soft termination technology and nickel barrier plating, targeting demanding industrial and automotive environments requiring enhanced durability.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative feed-through designs based on specific pass current and capacitance tolerances.
