GE 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 GE’s

Application Engineers. Please use this sheet if you need assistance or want to verify

your own calculations.
