Characteristic

 

Plastic Box Type are Metallized polypropylene Capacitors designed primarily for use in Motor run applications. They are also use in AC power supplies, fluorescent Lamp and other circuits. The low dielectric losses, the inherent "Self-healing" property, and the greatly increased microfarad per unit volume make these designs ideal where reliability and small size are essential.
