CPD 513 Rev. B 3-00 5k g GE Capacitors Capacitors for High Current, Power Semiconductor, and DC Applications GE TD&IS Transmission, Distribution & Industrial Systems, Fort Edward, NY 12828GE Capacitors for High-Current, Power Semiconductor, and DC Applications Capacitors for Power Electronics require special high-performance designs for the varied applications. This catalog describes capacitors for a number of demanding applications where high currents and/or high voltages are common. Given the special nature of these applications, care must be taken to ensure that the capacitors are correctly applied. Information is included to help with the more common application conditions. An Application Data Sheet is also provided to enlist the help of GEs Application Engineers. Please use this sheet if you need assistance or want to verify your own calculations.
