0805Y0500392MJTE07

Overview

The Knowles Syfer 0805Y0500392MJTE07 is a multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a capacitance of 3.90 nF with a tolerance of ±20%, utilizing X7R dielectric material. The component operates at a DC voltage rating of 50 V and supports a continuous current of 1 A. Housed in an 0805 (2012 Metric) surface-mount package, it offers flexible end terminations and a nickel barrier structure. The device functions within a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal architecture providing enhanced electromagnetic interference filtering capabilities
• Flexible soft end terminations to improve mechanical reliability during thermal cycling
• Nickel barrier electrode construction for robust solderability and structural integrity

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power line filtering for components requiring 1 A current handling
• EMI mitigation in compact surface-mount designs

Procurement Notes

Verify the specific ordering suffix against official Knowles Syfer documentation to confirm terminal configuration and termination plating. Ensure compatibility with automated pick-and-place equipment regarding the 0805 footprint dimensions. Confirm RoHS compliance status through the manufacturer's latest declaration before integration into regulated assemblies.

Selection Notes

Select this component when high-frequency attenuation is required alongside standard decoupling functions. The three-terminal design necessitates specific PCB layout considerations for ground plane connections. Evaluate the X7R temperature coefficient stability against circuit requirements within the specified operating range.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, characterized by flexible terminations that reduce stress on the ceramic body. The 0805 form factor allows for dense mounting in space-constrained applications while maintaining electrical performance standards for industrial and commercial electronics.

Replacement Considerations

Direct substitutes must match the 3.90 nF capacitance, 50 V rating, and three-terminal EMI filter topology. Verify that alternative parts support the same 1 A current rating and utilize compatible flexible termination technologies to ensure mechanical reliability.
