1806Y1000823MXTE01

Overview

The Knowles Syfer 1806Y1000823MXTE01 is a three-terminal feed-through ceramic capacitor designed for surface-mount applications. It features an 1806 (4516 metric) package with dimensions of 4.5 mm length, 1.6 mm width, and 1.1 mm height. The component provides a capacitance of 0.082 µF (82 nF) with a DC voltage rating of 100 V. It operates within a temperature range of -55°C to +125°C and includes a built-in 300 mA fuse element for overcurrent protection.

Feature Summary

• Three-terminal feed-through architecture providing superior high-frequency noise attenuation compared to standard two-terminal capacitors.
• Integrated internal fuse element offers circuit protection against overcurrent conditions by disconnecting the path upon failure.
• Low-inductance design facilitates effective electromagnetic interference suppression in compact surface-mount layouts.

Applications

• High-frequency noise filtering in sensitive electronic circuits
• Power supply input/output decoupling requiring overcurrent protection
• Electromagnetic interference suppression in communication equipment

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal configuration and fuse ratings. Ensure compatibility with the target PCB footprint, as three-terminal components require distinct pad arrangements compared to standard MLCCs. Cross-reference the electrical specifications with the latest datasheet to validate performance under operating conditions.

Selection Notes

Select this component when both high-frequency noise reduction and circuit protection are required in a single surface-mount device. The three-terminal design is essential for applications demanding lower parasitic inductance than standard capacitors. Consider the 300 mA fuse rating to ensure it aligns with the maximum allowable current for the protected line without nuisance tripping during normal operation.
