1206J1000273MXTE07

Overview

The Knowles Syfer 1206J1000273MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for EMI suppression. It features a 1206 package size with a capacitance of 27 nF and a DC voltage rating of 100 V. The dielectric material is X7R, providing a tolerance of ±20%. The component utilizes a three-terminal architecture with nickel barrier and 100% tin terminations to enhance electromagnetic interference filtering performance in compact circuit layouts.

Feature Summary

• Three-terminal structure optimized for high-frequency EMI noise attenuation
• Nickel barrier termination system ensuring robust solderability and mechanical stability
• X7R dielectric composition supporting stable electrical characteristics across operating temperatures

Applications

• High-density PCB designs requiring integrated EMI filtering
• Signal line protection in sensitive electronic circuits
• Power supply input stages for noise reduction

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and dielectric specifications. Confirm RoHS compliance status and specific packaging quantities directly with authorized distributors or the manufacturer prior to ordering, as availability and lot details may vary.

Selection Notes

Select this component when board space is limited but effective common-mode noise suppression is required. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Ensure the application voltage does not exceed the 100 VDC rating and that the X7R temperature coefficient aligns with the operational thermal environment.

Part Context

This component belongs to the Knowles Syfer MLCC portfolio, specifically engineered for surface-mount applications. The 1206J series designation indicates a standard 1206 footprint with J-series electrical parameters. It represents a specialized solution within the broader ceramic capacitor market, focusing on signal integrity and electromagnetic compatibility rather than bulk energy storage.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 100V rating, 27nF capacitance, X7R dielectric, and three-terminal EMI filter configuration. Verify termination material compatibility and lead-free status during cross-referencing.
