1206J2000122MXTE03

Overview

The Knowles Syfer 1206J2000122MXTE03 is a surface-mount X2Y capacitor filter designed for EMI suppression. It features a capacitance of 1.2 nF with a tolerance of ±20% and a DC voltage rating of 200 VDC. The component utilizes an X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it employs a three-terminal architecture with nickel barrier and 100% tin terminations. This configuration provides balanced common-mode and differential-mode noise attenuation capabilities.

Feature Summary

• Integrates X2Y technology to suppress both common-mode and differential-mode electromagnetic interference simultaneously.
• Utilizes a three-terminal internal structure for enhanced high-frequency noise filtering performance.
• Features nickel barrier and 100% tin terminations for reliable solderability and corrosion resistance.

Applications

• High-speed digital signal line protection
• Power supply input/output filtering
• EMI suppression in compact electronic modules

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination plating and packaging specifications. Confirm RoHS compliance status and specific datasheet revisions prior to procurement. Cross-reference ordering codes with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when space-constrained designs require simultaneous common-mode and differential-mode noise reduction. The 1206 footprint offers a balance between current handling and board area efficiency. Ensure the operating voltage remains below the 200 VDC rating and consider the X7R temperature coefficient for thermal stability requirements.

Part Context

This component belongs to the Knowles Syfer X2Y family of feedthrough capacitors. These devices are engineered to replace traditional discrete capacitor networks, reducing component count and parasitic inductance. The series is widely recognized for providing superior high-frequency performance in dense printed circuit board layouts compared to standard two-terminal MLCCs.
