Capacitor Hardware is an important capacitor accessory in many alternative energy systems, power inverters, power generating systems, and even consumer electronics products. In order to mechanically mount certain aluminum electrolytic, oil filled, power film, or other such capacitors, a variety of brackets, flanges, protective boots, protective caps, and other hardware pieces are necessary. Used properly, the hardware helps to minimize any adverse effects of vibration and ensure a reliable, long-lasting design.
