1206Y0500124METE03

Overview

The Knowles Syfer 1206Y0500124METE03 is a 0.12 µF feed-through capacitor rated at 50 VDC with a ±20% tolerance, utilizing X7R dielectric material. Designed in a 1206 (3216 metric) surface-mount package, it features a three-pad configuration and supports a continuous current of 50 mA. The component operates within a temperature range of -55°C to +125°C and incorporates FlexiCap™ soft termination technology for enhanced mechanical reliability.

Feature Summary

• Feed-through architecture providing integrated EMI filtering capabilities
• FlexiCap™ soft termination design to mitigate board flex stress
• Three-pad mounting structure for improved mechanical stability

Applications

• High-frequency signal line filtering
• Power distribution network decoupling
• EMI suppression in sensitive electronic circuits

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm terminal plating and packaging variations. Ensure the selected variant matches the required current rating and thermal specifications for the target application environment.

Selection Notes

Select this component when integrated filtering and mechanical robustness are required in space-constrained designs. The three-pad layout offers superior solder joint integrity compared to standard two-terminal MLCCs under mechanical stress conditions.

Part Context

This part belongs to the Knowles Syfer FlexiCap™ series, which specializes in high-reliability capacitors for automotive and industrial sectors. The series combines Class 2 dielectric performance with specialized termination technologies to address common failure modes in rigid PCB assemblies.

Replacement Considerations

Direct substitutes require matching the 1206 footprint, 50V rating, 0.12µF capacitance, and feed-through topology. Verify that alternative components support the 50mA current handling capability and maintain compatible thermal operating ranges.
