please suggest me which capacitor is best for my impulse generator ( magnetizer )

im getting ALCON Aluminium electrolytic capacitor

Model : PG-SR 105
Voltage : 450VDC
Capacitance : 4700 MFD
at 25$ per piece on local electronic store.
(i was unable to get data sheet )

but in alcon site Link2
they mentioned HED (high energy discharge ) capacitor specially for Capacitance Discharge Welding,Magnetism and other Pulse, Discharge Applications.

for voltage : 450VDc , capacitance : 4700MFD the company quoted 34$ per piece.
i am in confusion to chose the capacitors for my magnetizer
Wa0004

1457784252 54872 FT0 Hed Capacitor

I am confused. Thread title asks for suggestions, your text says you already bought/getting stuff.
The little i found on the PG-6SR series suggested that they are pretty normal capacitors (ESR-wise).

I am not sure what you expect currently. Just build the thing and continue. Even normal capacitors can handle their own stored energy dissipated within them selfes at least 100x without significant damage. So dont worry too much about the capacitors right now. Use the ones you spent money on and be happy smile

The HED-Series wont give you significantly higher current nor better life time.. or energy density or whatever. Its still aluminium electrolytic based, so its limit is right there...
I mean how do you expect us to give you any assurances anyway... neither the company in their datasheet for the HED-Series nor you specify any current rating. rolleyes
