These universal motor run capacitors have a round shape. They can be wired to a range of capacitance values, measured in microfarads (mfd or µF), reducing the need to maintain an assortment of capacitors with different ratings. These capacitors can be wired as dual run capacitors that contain two capacitance values in a single unit, compared to standard capacitors that have one capacitance value. One dual run capacitor can take the place of two single run capacitors, and can connect to two motors placed closed together. These versatile capacitors are useful when working in the field.
