1206Y0500103MJTE03

Overview

The Knowles Syfer 1206Y0500103MJTE03 is a surface-mount feedthrough capacitor featuring a 10 nF capacitance and a 50 VDC voltage rating. It utilizes X7R (2R1) dielectric material with a ±20% tolerance. The component operates within a temperature range of -55°C to +125°C. It employs a three-terminal architecture housed in a 1206 (3216 metric) package, utilizing nickel barrier and 100% tin terminations for SMD/SMT mounting.

Feature Summary

• Three-terminal X2Y filter architecture providing enhanced electromagnetic interference suppression
• Nickel barrier termination structure ensuring robust solderability and reliability
• X7R dielectric composition supporting stable performance across specified operating temperatures

Applications

• High-frequency signal line filtering in electronic circuits
• Power supply decoupling for noise reduction
• Electromagnetic interference mitigation in sensitive communication devices

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm terminal configuration and packaging details. Ensure compatibility with existing PCB footprints designed for three-terminal feedthrough capacitors. Cross-reference datasheet revisions to validate current manufacturing status and compliance certifications before finalizing procurement plans.

Selection Notes

Select this component when integrated EMI filtering is required without additional discrete components. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal MLCCs. Evaluate thermal management requirements against the X7R dielectric characteristics and ensure the 50V rating exceeds peak circuit voltages.
