1806Y0250404MXTE07

Overview

The Knowles Syfer 1806Y0250404MXTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.4 µF with a ±20% tolerance and an X7R dielectric material. The component is rated for a DC voltage of 25V and supports a continuous current of 2A. Housed in a compact 1806 (4516 metric) package, it utilizes flexible terminal technology to enhance mechanical reliability on flex-sensitive boards.

Feature Summary

• Integrated feed-through architecture provides effective electromagnetic interference filtering within a single compact footprint.
• Flexible terminal construction reduces mechanical stress on the substrate, improving durability on board-flex sensitive applications.

Applications

• High-frequency noise suppression in communication equipment
• Power line filtering for sensitive electronic circuits
• Electromagnetic interference mitigation in mobile devices

Procurement Notes

Verify the complete part number including the suffix to ensure correct termination and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the datasheet for specific handling requirements related to moisture sensitivity and reflow soldering profiles to maintain component integrity during assembly.

Selection Notes

Select this component when space constraints require a combined filtering and decoupling solution in a standard 1806 footprint. The 2A current rating makes it suitable for power rail applications where significant ripple currents are present. Ensure the operating temperature range aligns with the X7R dielectric characteristics for stable performance across varying thermal conditions.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors with soft or flexible terminations. The series is engineered to address mechanical failures caused by board bending or warping, making it distinct from standard rigid-termination MLCCs used in general-purpose electronics.

Replacement Considerations

Direct replacements must match the 1806 package dimensions, 0.4 µF capacitance, 25V rating, and feed-through topology. Verify that any substitute also offers flexible terminals if board-flex sensitivity is a design constraint. Consult official substitution guides for equivalent electrical performance and mechanical compatibility.
