1806Y0250392MJTE07

Overview

The Knowles Syfer 1806Y0250392MJTE07 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a 3900 pF capacitance with a ±20% tolerance and a DC voltage rating of 25 VDC. The component utilizes X7R dielectric material, ensuring stable performance across a wide temperature range from -55°C to +125°C. Housed in an 1806 (4516 metric) package, it integrates a nickel barrier structure for enhanced reliability. This three-terminal device supports up to 2 A current handling, making it suitable for high-frequency noise suppression applications.

Feature Summary

• Integrates a three-terminal feed-through architecture for effective electromagnetic interference filtering within a compact surface-mount footprint.
• Incorporates a flexible nickel barrier construction to improve mechanical robustness and resistance to thermal shock during soldering processes.
• Utilizes X7R dielectric characteristics to maintain consistent capacitance stability under varying environmental temperatures and electrical loads.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Electromagnetic interference (EMI) filtering for signal integrity preservation
• Power supply decoupling in compact mobile devices

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm terminal configuration and packaging details. Ensure compatibility with standard reflow soldering profiles by consulting the published thermal profile guidelines. Cross-reference the RoHS compliance status with current regulatory requirements before integration into final assemblies.

Selection Notes

Select this component when a feed-through topology is required for superior high-frequency attenuation compared to standard two-terminal capacitors. The 1806 case size offers a balance between current handling capability and board space efficiency. Consider the X7R dielectric properties if moderate temperature stability suffices for the application environment.
