1206J1000272MXTE01

Overview

The Knowles Syfer 1206J1000272MXTE01 is a three-terminal surface-mount EMI filter capacitor housed in a 1206 (3216 metric) package. It features an X7R dielectric with a capacitance of 2.7 nF and a DC voltage rating of 100 VDC. The component offers a tolerance of ±20% and operates within a temperature range of -55°C to +125°C. Termination consists of nickel barrier plating with 100% tin, designed for high-reliability applications requiring effective electromagnetic interference suppression.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering performance compared to standard two-terminal capacitors.
• Utilizes X7R ceramic dielectric material to maintain stable electrical characteristics across the specified operating temperature range.
• Features nickel barrier termination technology with 100% tin plating to ensure robust solderability and long-term reliability.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Electromagnetic interference (EMI) filtering in communication equipment
• Signal integrity protection in industrial control systems

Procurement Notes

Verify the specific suffix MXTE01 against official Knowles Syfer documentation to confirm the three-terminal EMI filter configuration and termination specifications. Ensure compatibility with PCB footprint requirements for three-terminal devices. Confirm RoHS compliance status through current manufacturer declarations prior to integration into production assemblies.

Selection Notes

Select this component when superior high-frequency attenuation is required over standard MLCCs. The three-terminal design effectively grounds noise currents, reducing radiated emissions. Verify that the 100V rating and 2.7nF capacitance align with circuit impedance and voltage constraints. Consider the 1206 package dimensions for spatial limitations on the printed circuit board layout.

Part Context

This component belongs to the Knowles Syfer EMI Filter series, specifically designed for surface-mount assembly. It represents a specialized class of multilayer ceramic capacitors engineered for noise suppression rather than general-purpose energy storage. The product line emphasizes reliability in harsh environments through advanced termination technologies.
