1806Y0250393MXTE07

Overview

The Knowles Syfer 1806Y0250393MXTE07 is a three-terminal feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an 1806 (4516 metric) package size with a capacitance of 0.039 µF and a DC voltage rating of 25V. The component utilizes X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. It includes a nickel barrier structure and is rated for 2A current handling.

Feature Summary

• Three-terminal feed-through architecture for enhanced electromagnetic interference filtering
• Nickel barrier construction integrated within the electrode structure
• X7R dielectric material ensuring reliable capacitance stability over wide temperature variations
• Surface mount design optimized for high-density board layouts

Applications

• Electromagnetic interference suppression in sensitive electronic circuits
• Power line filtering for low-voltage DC applications
• Signal integrity protection in communication equipment
• Board-level noise reduction in consumer electronics

Procurement Notes

Verify the specific suffix codes against official Knowles Syfer documentation to confirm terminal configuration and termination plating. Ensure compatibility with automated pick-and-place equipment regarding the 1806 footprint dimensions. Cross-reference the RoHS compliance status with the latest manufacturer declarations prior to final procurement approval.

Selection Notes

Select this component when three-terminal EMI filtering is required in a compact 1806 footprint. The 25V rating suits low-voltage digital and analog power rails. Consider the nickel barrier feature for environments requiring robust internal electrode protection. Validate thermal management requirements against the X7R temperature coefficient limits during operation.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in flexible termination technologies to withstand board flex stress. The 1806Y prefix indicates a standard 1806 case size with Y-series characteristics. As a feed-through capacitor, it integrates filtering directly into the signal path, reducing the need for additional discrete components.
