2A224J 100V Mylar Polyester Film Capacitor

2A224J 100V Polyester Film Capacitor provides a highly reliable and stable capacitive solution for general-purpose electronic filtering, coupling, and decoupling applications. This 0.22 μF (220nF) component utilizes a non-inductive construction with a metallized polyester film dielectric to ensure excellent self-healing properties. Consequently, the capacitor maintains its integrity even after internal dielectric breakdowns caused by transient overvoltages. Furthermore, its compact “Green Drop” or “Mylar” style epoxy coating offers robust protection against humidity and mechanical stress. Therefore, you should choose the 2A224J for precision timing or noise suppression tasks where space and cost-efficiency are paramount.

Key Features:

• High Insulation Resistance: The polyester film ensures minimal leakage current, making it suitable for high-impedance circuit applications.
• Self-Healing Dielectric: This feature allows the capacitor to recover from localized internal discharges, significantly extending the component’s operational lifespan.
• Low Dissipation Factor: It exhibits minimal energy loss during operation, which reduces heat generation in high-frequency signal environments.
• Broad Operating Temperature: The robust epoxy resin coating enables stable performance across a wide range of environmental conditions.
• Non-Polarized Design: However, unlike electrolytic types, this capacitor is non-polar, which simplifies installation as it functions in either direction.
