1206J0500103MJTE03

Overview

The Knowles Syfer 1206J0500103MJTE03 is a three-terminal feedthrough capacitor designed for surface mount technology. It features a 10 nF capacitance with a ±20% tolerance, rated for 50 VDC. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates a nickel barrier termination structure with 100% tin plating. This configuration supports high-frequency noise suppression in compact electronic assemblies.

Feature Summary

• Three-terminal architecture providing enhanced high-frequency filtering capabilities compared to standard two-terminal designs.
• X7R ceramic dielectric ensures stable capacitance performance across the specified industrial operating temperature range.
• Nickel barrier termination system combined with 100% tin plating offers reliable solderability and corrosion resistance.

Applications

• High-frequency EMI/RFI noise suppression in sensitive signal lines
