0805J0250392MXTE01

Overview

The Knowles Syfer 0805J0250392MXTE01 is a 3-terminal EMI filter capacitor housed in an 0805 (2012 metric) surface-mount package. It features a capacitance of 3900 pF with a voltage rating of 25 VDC and a tolerance of ±20%. The device utilizes X7R dielectric material and incorporates a nickel barrier with 100% tin terminations for solderability.

Feature Summary

• Integrated 3-terminal architecture designed for effective electromagnetic interference suppression
• Nickel barrier termination system ensuring reliable soldering performance
• X7R dielectric composition providing stable electrical characteristics across operating temperatures

Applications

• High-frequency noise filtering in compact electronic circuits
• Power supply line decoupling requiring EMI mitigation
• Signal integrity protection in dense surface-mount assemblies

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal structure and termination materials. Ensure compatibility with automated pick-and-place equipment regarding the 0805 footprint dimensions. Confirm RoHS compliance status through current manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when space-constrained designs require integrated EMI filtering capabilities alongside standard decoupling functions. The 3-terminal design offers superior high-frequency attenuation compared to standard 2-terminal capacitors in similar packages. Evaluate thermal management requirements as X7R characteristics vary with temperature changes.

Part Context

This part belongs to the Knowles Syfer general type MLCC series, specifically engineered for surface-mount applications. It represents a specialized variant within the broader ceramic capacitor portfolio, focusing on combined capacitance and filtering performance rather than pure energy storage.
