1206Y0250204MJTE07

Overview

The Knowles Syfer 1206Y0250204MJTE07 is a three-terminal feed-through multilayer ceramic capacitor designed for surface mount applications. It features a 1206 (3216 metric) package size with a rated DC voltage of 25V and a capacitance value of 0.2 µF (200 nF). The component utilizes X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. It incorporates a nickel barrier termination system and flexible soft terminations to enhance mechanical reliability. This device functions as an EMI filter, offering high current handling capabilities up to 2A while maintaining low impedance characteristics for noise suppression.

Feature Summary

• Three-terminal feed-through architecture provides effective electromagnetic interference filtering in a compact surface-mount form factor.
• Flexible soft terminations reduce stress on the capacitor body and printed circuit board during thermal cycling and mechanical flexing.
• Nickel barrier termination structure ensures robust solderability and long-term connection integrity under harsh environmental conditions.

Applications

• High-reliability electronic systems requiring board-flex sensitivity mitigation
• Electromagnetic interference suppression in signal and power lines
• Automotive electronics operating within extended temperature ranges

Procurement Notes

Verify that the specific application requires a three-terminal feed-through topology rather than standard two-terminal capacitors. Confirm that the 25V DC rating and 2A current handling capacity align with the circuit's operational limits. Ensure the PCB layout accommodates the specific pad configuration required for three-terminal devices to achieve optimal filtering performance. Check for any specific handling requirements related to the flexible termination structure during assembly.

Selection Notes

Select this component when both EMI filtering and mechanical durability are critical priorities. The combination of X7R dielectric and flexible terminations makes it suitable for environments subject to vibration or thermal expansion mismatch. Consider the physical dimensions of the 1206 package to ensure compatibility with the available footprint on the target printed circuit board. Evaluate the trade-off between the higher cost of three-terminal designs versus the performance benefits for the specific noise profile.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors featuring soft, flexible terminations. The series is engineered to address reliability issues associated with rigid terminations in high-stress applications. The 1206Y prefix indicates the 1206 package size and general product line classification within the manufacturer's portfolio of high-reliability passive components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Any replacement must match the three-terminal feed-through configuration, 1206 package dimensions, 25V rating, and 0.2 µF capacitance. Verify that alternative components offer comparable flexibility in their termination structures to maintain mechanical reliability.
