1206J1000823MXTE01

Overview

The Knowles Syfer 1206J1000823MXTE01 is a surface-mount feedthrough capacitor designed for EMI suppression. It features an X7R dielectric with a capacitance of 0.082 µF and a tolerance of ±20%. The component supports a rated DC voltage of 100V and a maximum current of 300 mA. Housed in a 1206 (3216 metric) package, it operates within a temperature range of -55°C to +125°C. Insertion loss is specified at 40 dB @ 100 MHz.

Feature Summary

• Three-terminal feedthrough architecture provides effective electromagnetic interference filtering
• X7R ceramic dielectric ensures stable electrical performance across the operating temperature range
• High current handling capability supports direct integration into power supply lines

Applications

• Power line EMI filtering in electronic circuits
• Signal integrity protection in sensitive data interfaces
• Electromagnetic compatibility enhancement in industrial control systems

Procurement Notes

Verify that the specific MXTE01 suffix matches the required three-terminal configuration and nickel barrier termination. Confirm insertion loss requirements align with the 40 dB specification at 100 MHz. Ensure PCB layout accommodates the distinct ground terminal geometry inherent to feedthrough designs rather than standard two-terminal MLCC footprints.

Selection Notes

Select this component when high-current EMI suppression is required in a compact surface-mount form factor. The 1206 footprint offers a balance between thermal mass and board space efficiency. Consider the X7R temperature characteristics if circuit stability is critical under varying thermal conditions compared to C0G alternatives.

Part Context

This part belongs to the Syfer EMI Filter series, specifically utilizing the E01/E07 SMT design family. It represents a specialized category of multilayer ceramic capacitors engineered for noise reduction rather than general-purpose energy storage or coupling functions.
