0805Y0250182MJTE07

Overview

The Knowles Syfer 0805Y0250182MJTE07 is a three-terminal EMI filter capacitor in an 0805 surface-mount package. It features a 25 VDC voltage rating and a capacitance of 1.8 nF with ±20% tolerance. The dielectric material is X7R, ensuring stability across a temperature range of -55°C to +125°C. This component utilizes a Nickel Barrier termination system and is designed for high-reliability applications requiring effective electromagnetic interference suppression.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering performance compared to standard two-terminal capacitors.
• Nickel Barrier termination technology ensures robust solderability and long-term reliability in harsh environments.
• X7R dielectric material maintains stable capacitance characteristics over a wide operating temperature range.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power supply input and output filtering stages
• Data line protection in communication interfaces

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and dielectric specifications. Confirm RoHS compliance status and packaging details directly with authorized distributors prior to ordering. Cross-reference datasheet revisions to validate current technical parameters.

Selection Notes

Select this component when board space constraints require an 0805 footprint but superior EMI attenuation is necessary. The three-terminal design offers better high-frequency performance than standard MLCCs. Ensure the circuit operates within the specified 25 VDC limit and temperature range for optimal reliability.

Part Context

This component belongs to the Knowles Syfer FlexiCap series of high-reliability multilayer ceramic capacitors. The series is engineered for demanding applications where mechanical stress resistance and electrical stability are critical. The specific model integrates EMI filtering capabilities within a compact surface-mount form factor.

Replacement Considerations

Direct substitutes must match the 0805 footprint, 25V rating, 1.8nF capacitance, X7R dielectric, and three-terminal EMI filter configuration. Verify termination compatibility and mounting orientation requirements before substitution.
