The 30 grams Mega capacitor delivers maximum capacity on a smaller footprint, low ESR and unrivaled performance to weight ratio. The Micro capacitor is an excellent improvement over the stock Digital-3 capacitor, this is a smaller footprint, lower profile and delivering 3x the capacity of the built in Digital 3 capacitor. All our new capacitors will ship with a custom built cradle made of carbon fiber nylon filament and 3M very high bond tape.
