1806J0250274MXTE07

Overview

The Knowles Syfer 1806J0250274MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-frequency applications. It features a capacitance of 270 nF with a tolerance of ±20% and a DC voltage rating of 25 VDC. Utilizing X7R dielectric material, this component operates within a temperature range of -55°C to +125°C. The device is housed in an 1806 (4516 metric) case size with SMD/SMT terminations. It incorporates a three-terminal EMI filter structure with nickel barrier and 100% tin plating, providing effective electromagnetic interference suppression.

Feature Summary

• Three-terminal EMI filter architecture for enhanced noise suppression
• X7R dielectric material for stable performance across operating temperatures
• Nickel barrier and 100% tin termination plating for reliable soldering

Applications

• High-frequency circuit filtering
• Electromagnetic interference suppression in signal lines
• Power supply decoupling in compact electronic devices

Procurement Notes

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

Selection Notes

Select this component when EMI filtering is required alongside standard capacitance values in space-constrained designs. The 1806 package offers a balance between current handling capability and board area efficiency. Ensure the application voltage does not exceed the 25 VDC rating and that the X7R temperature characteristics align with the operational environment requirements.

Part Context

This component belongs to the Knowles Syfer MLCC family, specifically engineered for surface-mount technology. It integrates passive filtering capabilities directly into the capacitor structure, reducing the need for separate inductive components. The product line emphasizes reliability and performance in demanding electronic environments.

Replacement Considerations

Direct substitutes must match the 1806 case size, 270 nF capacitance, 25 VDC rating, and three-terminal EMI filter topology. Verify compatibility of the X7R dielectric and termination materials with existing assembly processes.
