1806Y0250104MXTE01

Overview

The Knowles Syfer 1806Y0250104MXTE01 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an 1806 package size with a capacitance of 0.1 µF and a DC voltage rating of 25 VDC. The component utilizes C0G dielectric material, ensuring stable performance across its operating temperature range of -55°C to +125°C. It includes a built-in 300 mA fuse element for overcurrent protection and offers high isolation characteristics suitable for EMI suppression applications.

Feature Summary

• Integrated fuse element providing inherent overcurrent protection within the capacitor structure
• Feed-through architecture delivering high electromagnetic interference isolation
• C0G dielectric construction maintaining capacitance stability under varying thermal conditions

Applications

• High-frequency signal line filtering in communication equipment
• EMI suppression circuits requiring integrated surge protection
• Precision analog circuit power input conditioning

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal plating and fuse current ratings. Ensure compatibility with standard 1806 footprint dimensions during PCB layout. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when simultaneous EMI filtering and overcurrent protection are required in a single surface-mount package. The C0G dielectric ensures minimal capacitance drift, making it suitable for precision timing or coupling applications where stability is critical. Evaluate the 300 mA fuse threshold against maximum circuit load requirements.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which combines passive filtering with active protection mechanisms. Unlike standard MLCCs, these components integrate a fusible link directly into the electrode structure, offering a compact solution for protecting sensitive downstream electronics from transient current events while attenuating high-frequency noise.
