Hello,

I am looking for a high current (112A), high capacitance (0.5F) capacitor or capacitor bank (12V). I need the smallest size possible. I googled and contacted several manufacturers, but the ESR of the capacitors are too high (50 mΩ, Yes this is too high for me).
The application that I am working on is a power system requiring power bursts of 100ms in a 1 sec duration (10% duty). The burst should have 112A at 12V.
Is there anyone out there that has recommendations for me.
Also the outcome should not be expensive.

Thanks
