0805J0500393MJTE07

Overview

The Knowles Syfer 0805J0500393MJTE07 is a multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features an X7R dielectric material and offers a capacitance of 39,000 pF with a tolerance of ±20%. The component is rated for a DC voltage of 50 V and operates within a temperature range of -55°C to +125°C. It utilizes a 0805 package size with nickel barrier and 100% tin terminations.

Feature Summary

• X2Y three-terminal architecture for enhanced electromagnetic interference filtering
• Nickel barrier termination system ensuring reliable solderability
• High stability X7R dielectric characteristics for consistent performance

Applications

• Electromagnetic interference suppression in high-speed digital circuits
• Power supply decoupling for integrated circuits
• Signal line filtering in communication equipment

Procurement Notes

Verify the specific suffix TE07 against official datasheets to confirm the X2Y configuration and termination plating. Ensure compatibility with automated pick-and-place equipment regarding the 0805 footprint dimensions. Confirm RoHS compliance status through current manufacturer documentation before integration into production lines.

Selection Notes

Select this component when space-constrained designs require effective common-mode noise reduction. The X2Y structure provides superior high-frequency attenuation compared to standard two-terminal capacitors. Evaluate thermal management requirements to ensure operation remains within the specified -55°C to +125°C range during peak load conditions.

Part Context

This part belongs to the Knowles Syfer X2Y capacitor family, which integrates three terminals into a single surface-mount package. These components are engineered to provide both differential-mode and common-mode filtering capabilities simultaneously. The series is widely recognized for its compact form factor and robust EMI suppression performance in modern electronic assemblies.
