0805Y0250272MXTE07

Overview

The Knowles Syfer 0805Y0250272MXTE07 is a feed-through ceramic capacitor designed for surface-mount applications. It features a capacitance of 2700 pF with a ±20% tolerance and a DC voltage rating of 25 V. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range of -55°C to +125°C. Housed in an 0805 (2012 Metric) package, it integrates a built-in 1 A fuse element for overcurrent protection. The device employs flexible soft terminals to enhance reliability on board-flex sensitive substrates.

Feature Summary

• Integrated 1 A fuse element provides inherent overcurrent protection within the capacitor structure.
• Flexible soft terminal design reduces mechanical stress on the substrate during board flexing.
• X7R dielectric material ensures stable electrical performance across a wide industrial temperature range.

Applications

• Board-flex sensitive circuit designs requiring enhanced mechanical durability
• High-frequency EMI filtering circuits demanding integrated surge protection
• Compact surface-mount power supply input stages

Procurement Notes

Verify the specific suffix 'E07' against official datasheets to confirm the reel packaging configuration and terminal plating specifications. Ensure the selected variant matches the required 1 A fuse rating and 2700 pF capacitance value for the target application. Cross-reference the RoHS status and MSL classification with current manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when both high-frequency noise suppression and overcurrent protection are required in a single footprint. The 0805 size allows for dense PCB layouts while the integrated fuse eliminates the need for separate protective components. Consider the X7R temperature characteristics and 25 V rating to ensure adequate margin for the operating environment and voltage spikes.
