1206Y0500123MJTE07

Overview

The Knowles Syfer 1206Y0500123MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.012 µF with a voltage rating of 50 V and a current handling capacity of 2 A. The component utilizes an X7R dielectric material housed in a 1206 (3216 metric) package. Key structural attributes include flexible soft terminals to enhance board flexibility and a nickel barrier electrode system. It is compliant with RoHS standards and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated three-terminal feed-through architecture providing effective electromagnetic interference filtering
• Flexible soft terminal construction designed to reduce mechanical stress on the printed circuit board
• Nickel barrier electrode technology ensuring robust internal connection integrity

Applications

• High-speed digital signal line noise suppression
• Power supply input/output filtering
• RF circuit impedance matching and decoupling

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to confirm terminal type and termination plating. Ensure the selected variant matches the required current rating and capacitance tolerance for the target application. Cross-reference the official part number to distinguish between standard MLCC and feed-through filter versions within the FlexiCap series.

Selection Notes

Select this component when board flexure is a critical design constraint, as the soft terminals mitigate cracking risks during assembly or operation. The feed-through topology offers superior high-frequency attenuation compared to standard two-terminal capacitors. Confirm that the 50V rating and 2A current capacity align with the operational parameters of the circuit being filtered.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors featuring flexible terminations. The series targets applications requiring high reliability under mechanical stress. The 1206Y prefix indicates the 1206 case size and general product family classification within the manufacturer's portfolio.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 0.012 µF capacitance, 50V rating, and three-terminal feed-through structure. Verify compatibility of the nickel barrier electrode and soft terminal characteristics to maintain mechanical resilience.
