400v 150uF PhotoFlash Capacitor, Pulsed discharge, Low ESR

The PHOTOFLASH Capacitors are professionally manufactured and strictly controlled, to assure the best performance.
A unique internal structure allows for the repetitive pulsed discharge of the stored energy to happen without stressing the capacitor.

Capacitors are used to store the energy that will power the flash. They are charged relatively slowly, and discharged in a very short pulse duration by the flash.
The use of Photoflash type capacitors is common in applications like Medical IPL, Laser pumping, Coilguns and Railguns.
