1206Y0500392MJTE07

Overview

The Knowles Syfer 1206Y0500392MJTE07 is a 3-terminal feed-through multilayer ceramic capacitor designed for surface-mount applications. It features a 3900 pF capacitance with ±20% tolerance and an X7R dielectric, rated for 50 VDC. The component operates within a temperature range of -55°C to +125°C. It utilizes a nickel barrier electrode structure with 100% tin terminations housed in a standard 1206 (3216 metric) package.

Feature Summary

• Integrated EMI filtering capability through its 3-terminal feed-through architecture
• Robust termination system combining nickel barrier layers with 100% tin plating
• Stable electrical performance across wide industrial temperature variations

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power supply input/output filtering stages
• Signal line protection against electromagnetic interference

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal composition and dielectric characteristics. Ensure compatibility with automated pick-and-place equipment regarding the 1206 footprint dimensions. Confirm RoHS compliance status through current datasheets prior to integration into regulated assemblies.

Selection Notes

Select this component when board space constraints require a compact 1206 form factor alongside effective high-frequency noise attenuation. The 3-terminal design offers superior RF bypassing compared to standard 2-terminal capacitors. Consider the X7R dielectric stability requirements relative to the operating voltage and temperature conditions of the target application circuit.

Part Context

This part belongs to the Knowles Syfer family of high-reliability ceramic capacitors. The 1206Y series specifically targets applications requiring robust EMI suppression in compact surface-mount layouts. These components are engineered for consistent performance in demanding electronic environments where signal integrity is critical.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 3-terminal feed-through topology, and 50V rating. Verify that alternative parts maintain equivalent capacitance values and EMI suppression characteristics to ensure circuit functionality remains unchanged during replacement.
