1206J0500103MJTE07

Overview

The Knowles Syfer 1206J0500103MJTE07 is a 10 nF feed-through capacitor rated for 50 VDC with a 2 A current capacity. It utilizes C0G (NP0) dielectric technology housed in a 1206 (3216 metric) surface-mount package. The component features a three-terminal EMI filter design with nickel barrier and 100% tin terminations, ensuring reliable performance across an operating temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal EMI filter architecture providing superior high-frequency noise suppression compared to standard two-terminal capacitors.
• Feed-through design integrates filtering directly into the signal path, minimizing parasitic inductance for enhanced electromagnetic interference mitigation.
• Utilizes stable C0G (NP0) ceramic dielectric material to maintain consistent capacitance values under varying voltage and temperature conditions.

Applications

• High-speed data line filtering in communication interfaces
• Power supply input filtering for sensitive electronic circuits
• EMI suppression in automotive electronics systems

Procurement Notes

Verify the specific suffix configuration against official Knowles Syfer documentation to ensure correct termination plating and barrier layer specifications. Confirm that the three-terminal feed-through footprint matches your PCB layout requirements, as this component differs physically from standard MLCCs. Cross-reference the manufacturer datasheet for precise mechanical dimensions and soldering profile recommendations to guarantee assembly integrity.

Selection Notes

Select this component when high-frequency noise attenuation is critical on lines carrying significant current up to 2 A. The three-terminal structure offers lower effective series inductance than conventional capacitors, making it suitable for broadband EMI suppression. Ensure the application environment remains within the specified -55°C to +125°C operational range to maintain C0G dielectric stability and long-term reliability.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor family, designed specifically for electromagnetic interference filtering in compact surface-mount applications. Unlike standard multilayer ceramic capacitors, these components integrate a central conductor pass-through, allowing them to handle higher currents while providing effective common-mode and differential-mode noise reduction in tight spaces.

Replacement Considerations

Direct substitutes require matching the 1206 footprint, 10 nF capacitance, 50 V rating, and three-terminal feed-through topology. Verify that alternative parts support the same 2 A current handling capability and utilize compatible termination materials for solderability.
