1206Y0500153MXTE07

Overview

The Knowles Syfer 1206Y0500153MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a 15 nF capacitance with a ±20% tolerance and an X7R dielectric material. The component operates at a DC voltage rating of 50 V and utilizes a 1206 (3216 metric) package size. It incorporates FlexiCap termination technology, which provides enhanced mechanical reliability against board stress and thermal cycling.

Feature Summary

• Three-terminal architecture functions as an integrated EMI filter for noise suppression
• FlexiCap termination material accommodates PCB bending and reduces cracking risk
• X7R dielectric ensures stable capacitance performance across wide temperature ranges

Applications

• High-frequency signal line filtering in electronic circuits
• Power supply input stages requiring common-mode noise reduction
• Automotive electronics assemblies subject to mechanical vibration
• Industrial control systems demanding high reliability under thermal stress

Procurement Notes

Verify the specific manufacturing lot date code upon receipt to ensure compliance with project timeline requirements. Confirm that the received components match the 1206Y0500153MXTE07 designation exactly. Inspect terminations for integrity prior to assembly. Ensure storage conditions adhere to manufacturer guidelines to prevent moisture absorption before reflow soldering processes are initiated.

Selection Notes

Select this component when simultaneous capacitance and EMI filtering are required within a single footprint. The FlexiCap termination makes it suitable for applications involving rigid PCBs or significant mechanical strain. Compare electrical specifications against standard two-terminal MLCCs to confirm the added filtering capability meets circuit design goals without increasing board space.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in robust SMD capacitors. The series is engineered to withstand board flexing and extreme temperature cycling better than conventional terminations. It represents a solution for designers needing to combine energy storage with electromagnetic interference mitigation in compact form factors.

Replacement Considerations

Direct substitutes must maintain the 1206 footprint, 50V rating, 15nF value, and three-terminal EMI filter structure. Verify that alternative parts also feature flexible terminations if mechanical reliability is critical. Standard two-terminal capacitors cannot replace this component due to the lack of inherent filtering functionality.
