1206Y1000273MXTE07

Overview

The Knowles Syfer 1206Y1000273MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for EMI filtering applications. It features a 1206 (3216 metric) package size with a capacitance of 27 nF and a voltage rating of 100 VDC. The component utilizes X7R dielectric material with a tolerance of ±20%. It incorporates FlexiCap™ technology, providing flexible terminations to withstand board flexing and thermal cycling. The device includes an integrated nickel barrier and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates three-terminal EMI filter functionality within a standard SMD footprint
• Features proprietary FlexiCap™ termination material for enhanced mechanical reliability under board stress
• Utilizes X7R dielectric for stable performance across the specified operating temperature range

Applications

• EMI suppression in high-density electronic assemblies
• Applications requiring resistance to board bending or flexing
• Power supply input/output filtering circuits

Procurement Notes

Verify the specific suffix MXTE07 against official Knowles Syfer documentation to confirm the presence of the integrated EMI filter structure and terminal configuration. Ensure that the procurement specifications align with the required 100V DC rating and 27 nF capacitance values. Confirm compliance with RoHS directives and check for any specific handling requirements associated with the flexible termination materials during assembly processes.

Selection Notes

Select this component when both EMI filtering and mechanical durability are critical design constraints. The 1206 package offers a balance between capacitance value and board space efficiency. Consider the X7R dielectric characteristics for general-purpose applications where moderate temperature stability is sufficient. Evaluate the need for the integrated filter topology versus discrete components based on layout complexity and noise reduction requirements.

Part Context

This part belongs to the Syfer FlexiCap™ series, which specializes in MLCCs with flexible terminations to improve reliability in dynamic environments. The 1206Y prefix indicates the 1206 case size and X7R dielectric type. The MXTE07 suffix typically denotes specific packaging and terminal configurations, including the nickel barrier plating. This series is engineered to meet stringent automotive and industrial standards for mechanical robustness.

Replacement Considerations

Direct substitutes must match the 1206 package, 100V rating, 27 nF capacitance, and X7R dielectric. Verify if alternative parts offer compatible EMI filtering capabilities and similar FlexiCap™ mechanical properties. Cross-reference pinout and electrical parameters with official datasheets before substitution.
