SFA66T4K288B-F is an AC rated metallized polypropylene capacitor designed for motor-run and power supply applications. This capacitor features a 4.0 µF capacitance with a 660 Vac rated voltage, housed in an aluminum oval case (Case Code A) with a height of 2.88 inches. It offers self-healing capability, low energy consumption with a dissipation factor of less than 0.1%, and operates over a temperature range of -40°C to 70°C. The capacitor is encapsulated with environmentally safe dielectric fluid and features tin plated steel terminals with 4-tine 1/4" quick connect lugs. Ideal for refrigeration and air conditioning motor-run applications, as well as noise suppression, voltage regulation, and line current reduction in power supply applications.
