1206Y0500154MJTE07

Overview

The Knowles Syfer 1206Y0500154MJTE07 is a surface-mount multilayer ceramic capacitor designed for high-reliability applications. It features a 1206 (3216 metric) package size with a rated DC voltage of 50V and a capacitance value of 0.15 µF (150 nF). The component utilizes X7R dielectric material, providing a tolerance of ±20%. It incorporates a three-terminal EMI filter architecture with a nickel barrier and 100% tin termination system. This configuration supports effective electromagnetic interference suppression in compact circuit designs.

Feature Summary

• Three-terminal EMI filter architecture for enhanced noise suppression
• Nickel barrier construction with 100% tin terminations for reliability
• X7R dielectric material ensuring stable performance across temperature ranges

Applications

• Electromagnetic interference filtering in electronic circuits
• High-reliability surface-mount assembly environments
• Power supply input/output noise reduction stages

Procurement Notes

Verify the specific manufacturer part number against official Knowles Syfer documentation to confirm compatibility. Ensure that the required voltage rating, capacitance tolerance, and package dimensions align with the target design specifications. Confirm RoHS compliance status and check for any regional distribution restrictions or limited availability notices prior to finalizing procurement plans.

Selection Notes

Select this component when integrated EMI filtering is required within a standard 1206 footprint. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Consider the X7R dielectric characteristics for general-purpose applications where moderate capacitance stability is sufficient. Evaluate the nickel barrier termination for solderability and mechanical strength requirements.

Part Context

This component belongs to the Knowles Syfer series of high-reliability multilayer ceramic capacitors. It is specifically engineered as an EMI filter, distinguishing it from standard bypass or decoupling capacitors through its internal electrode structure. The product line emphasizes robustness and consistent electrical performance for demanding industrial and commercial electronics applications.

Replacement Considerations

Direct substitutes must match the 1206 package, 50V rating, 0.15 µF capacitance, and three-terminal EMI filter topology. Verify that alternative components maintain equivalent X7R dielectric properties and nickel barrier termination systems to ensure identical mounting and filtering characteristics.
