1206Y0500273MSTE03

Overview

The Knowles Syfer 1206Y0500273MSTE03 is a surface-mount feed-through capacitor in a 1206 (3216 metric) package. It features a capacitance of 0.027 µF with a voltage rating of 50 VDC and a tolerance of ±20%. The component utilizes X7R dielectric material and is rated for operation between -55°C and +125°C. Designed for high-frequency noise suppression, it supports a maximum current of 50 mA.

Feature Summary

• Integrated feed-through architecture provides effective electromagnetic interference filtering within a compact footprint.
• Flexible terminal construction enhances mechanical reliability by absorbing board flex stress to prevent cracking.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power line filtering for components requiring EMI reduction
• Applications involving printed circuit board flex or vibration

Procurement Notes

Verify the specific suffix MSTE03 against official datasheets to confirm the feed-through configuration and nickel barrier plating. Ensure compatibility with automated pick-and-place equipment regarding the reel packaging format. Confirm that the 50 mA current rating meets the operational requirements of the target circuit path without exceeding thermal limits.

Selection Notes

Select this component when integrated EMI filtering is required alongside standard decoupling functions in space-constrained designs. The feed-through structure allows for direct signal path integration, reducing the need for additional discrete filter components. Consider the X7R temperature stability characteristics relative to the operating environment's thermal profile.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in robust ceramic capacitors designed for automotive and industrial environments. The series emphasizes durability through flexible termination technology, addressing common failure modes associated with mechanical stress on rigid MLCCs during assembly or service.

Replacement Considerations

Direct substitutes must match the 1206 feed-through form factor, 0.027 µF capacitance, and 50 V rating. Verify that alternative components offer comparable current handling capabilities and compatible termination styles to maintain mechanical integrity.
