1806J0250404MXTE07

Overview

The Knowles Syfer 1806J0250404MXTE07 is a three-terminal surface-mount EMI filter capacitor in an 1806 (4516 metric) package. It features a 25 VDC voltage rating and a capacitance of 400 nF with a ±20% tolerance. The component utilizes X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. End terminations consist of a nickel barrier with 100% tin plating, suitable for standard SMD/SMT assembly processes.

Feature Summary

• Three-terminal architecture designed for effective electromagnetic interference suppression
• Nickel barrier with 100% tin end terminations for reliable solderability
• X7R dielectric composition providing consistent electrical characteristics over wide temperature variations

Applications

• High-frequency noise filtering in compact electronic circuits
• Power supply line conditioning for sensitive digital components
• EMI suppression in telecommunications equipment signal paths

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and packaging specifications. Confirm RoHS compliance status through current datasheets or environmental declarations prior to integration into regulated assemblies.

Selection Notes

Select this component when space-constrained designs require high capacitance values within the 1806 footprint. The three-terminal structure offers superior high-frequency attenuation compared to standard two-terminal capacitors. Ensure circuit operating voltages remain below the 25 VDC rating to maintain reliability.

Part Context

This component belongs to the Knowles Syfer MLCC series, specifically engineered as an EMI filter. The brand specializes in application-specific passive components, distinguishing these filters from general-purpose ceramic capacitors through their specialized internal electrode geometry for enhanced noise reduction.

Replacement Considerations

Cross-reference with other 1806 package three-terminal EMI filters from the same manufacturer family. Verify that substitute parts match the 400 nF capacitance, 25 VDC rating, and X7R dielectric class to maintain equivalent filtering performance.
