General Atomics Energy Products (GAEP) designs and manufactures large energy storage / pulse discharge capacitors using a variety of dielectric and electrode systems that are optimized for different applications. Formerly known as Maxwell Energy Products, GAEP has a large manufacturing capacity for such capacitors and has delivered over 500 MJ since 1966. Examples demonstrating GAEP manufacturing capability are shown in Table 1. Such large capacitors are usually custom-designed for each application, but GAEP does maintain an inventory of standard materials that can be utilized for rapid prototyping. This document will review the available technologies used by GAEP and the applications for which they are most appropriate. Type C capacitors are large capacitors in fabricated, welded steel cases. Typical Type C capacitor cases range from 7-1/4 x 14 x 25 inches to 12 x 16 x 28-1/2 inches. A variety of high voltage terminals, current returns, and mounting schemes are available. GAEP’s Type C Extended Foil capacitors offer the highest peak currents of any type of capacitor, up to one million Amps for a single unit. GAEP’s low profile bushings and internal construction techniques result in low inductance (30-200 nH), and low Equivalent Series Resistance (ESR). Coaxial current return rings are available for each style of bushing when the lowest inductance is required for fast discharge applications.
Products & Services
Tantalum capacitors are used in smaller electronic devices including portable telephones, pagers, personal computers, and automotive electronics. 
Ceramic capacitors have a dielectric made of ceramic materials.
Chip capacitors or surface mount capacitors do not have leads.
Film capacitors are insulated with polyester, polycarbonate, polypropylene, polystyrene, or other dielectric materials.
Aluminum electrolytic capacitors use an electrolytic process to form the dielectric. Wet electrolytic capacitors have a moist electrolyte. Dry or solid electrolytic capacitors do not.
