1206Y0500273MJTE07

Overview

The Knowles Syfer 1206Y0500273MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a capacitance of 27.00 nF with a tolerance of ±20% and utilizes X7R dielectric material. The component is rated for a maximum voltage of 50V and operates within a temperature range of -55°C to +125°C. It employs a FlexiCap/Nickel Barrier construction with 100% tin terminations, housed in a standard 1206 (3216 Metric) package.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering performance compared to standard two-terminal capacitors.
• FlexiCap technology incorporates soft termination ends to mitigate mechanical stress and prevent cracking during board flexing or thermal cycling.
• Nickel barrier layer protects the internal electrode structure from solder wicking during the reflow soldering process.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power supply input and output filtering stages
• Signal line protection in automotive electronics
• EMI mitigation in telecommunications equipment

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct termination and barrier specifications. Confirm RoHS compliance status through current datasheets. Check for regional distribution restrictions or limited availability notices prior to ordering. Ensure compatibility with automated pick-and-place equipment regarding the reel packaging format.

Selection Notes

Select this component when superior high-frequency attenuation is required over standard MLCCs. The three-terminal design offers lower parasitic inductance. Consider the FlexiCap feature if the application involves significant mechanical stress on the PCB. Verify that the 50V rating meets the circuit's peak voltage requirements including derating factors.

Part Context

This part belongs to the Knowles Syfer 1206Y series of flexible terminal EMI filters. These components are engineered for reliability in demanding environments, combining the electrical characteristics of ceramic capacitors with the structural benefits of specialized termination technologies for robust surface-mount assembly.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 27nF capacitance, 50V rating, and three-terminal EMI filter topology. Verify that alternative parts also offer X7R dielectric and compatible termination materials to maintain solderability and mechanical integrity.
