1206Y0500563MSTE03

Overview

The Knowles Syfer 1206Y0500563MSTE03 is a surface-mount multilayer ceramic feed-through capacitor designed for high-reliability applications. It features a capacitance of 0.056 µF with a ±20% tolerance and a rated DC voltage of 50 V. Utilizing X7R dielectric material, the component operates within a temperature range of -55°C to +125°C. The device employs FlexiCap technology with nickel barrier electrodes to enhance mechanical robustness against board flexure. It is packaged in reels for automated surface-mount assembly.

Feature Summary

• Integrates FlexiCap flexible electrode technology with nickel barriers to mitigate stress from PCB bending and thermal cycling.
• Functions as a feed-through capacitor, providing internal signal filtering while maintaining structural integrity under mechanical strain.
• Constructed with X7R dielectric material to ensure stable capacitance performance across a wide industrial temperature range.

Applications

• Automotive electronics requiring AEC-Q200 compliance and resistance to board flexure.
• High-reliability industrial systems subject to mechanical vibration or thermal shock.
• Signal conditioning circuits in space-qualified or military-grade equipment.

Procurement Notes

Verify the specific suffix MSTE03 to confirm the inclusion of FlexiCap nickel barrier construction and feed-through topology. Ensure the procurement specification matches the required 50V rating and 0.056 µF capacitance. Confirm that the application environment supports the X7R dielectric characteristics and the specified operating temperature limits. Validate packaging requirements against standard reel quantities provided by the manufacturer.

Selection Notes

Select this component when mechanical durability is critical due to substrate flexibility or thermal expansion mismatches. The FlexiCap design addresses common failure modes associated with rigid terminations in high-stress environments. Consider the feed-through architecture if internal shielding or compact footprint filtering is required. Verify that the X7R temperature coefficient aligns with the circuit's stability requirements across the intended operational range.
