1806Y1000393MXTE07

Overview

The Knowles Syfer 1806Y1000393MXTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a 0.039 µF capacitance with ±20% tolerance and an X7R dielectric material. The component is rated for 100 VDC and supports a continuous current of 2 A. Housed in a compact 1806 (4516 metric) package, it operates within a temperature range of -55°C to +125°C. This part belongs to the FlexiCap series, which incorporates flexible terminations to enhance mechanical reliability.

Feature Summary

• Integrated feed-through architecture providing efficient electromagnetic interference filtering in a single surface-mount component
• Flexible termination technology designed to absorb mechanical stress and reduce the risk of cracking during board flexing or thermal cycling

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• EMI suppression in automotive electronics
• Noise reduction in communication equipment

Procurement Notes

Verify the specific suffix TE07 against official datasheets to confirm packaging configuration and terminal plating specifications. Ensure compatibility with standard reflow soldering profiles for lead-free assembly processes. Cross-reference the manufacturer's latest revision history to confirm compliance with current environmental directives such as RoHS and REACH requirements before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a feed-through topology within a standard 1806 footprint. The X7R dielectric offers stable performance across the specified operating temperature range. Consider the 2 A current rating to ensure adequate handling for the target circuit application without exceeding thermal limits. Verify that the ±20% tolerance aligns with the system's noise rejection requirements.

Part Context

This component is part of the Knowles Syfer FlexiCap family, which specializes in multilayer ceramic capacitors with enhanced mechanical durability. The 1806Y series designation indicates a feed-through structure optimized for high-current applications. The product integrates filtering capabilities directly into the mounting pad layout, simplifying PCB design compared to discrete filter networks.

Replacement Considerations

Direct substitutes must match the 1806 feed-through form factor, 100V rating, and 0.039µF value. Verify that alternative components support similar current handling and possess compatible flexible termination characteristics to maintain mechanical integrity in flex-sensitive designs.
