My C1 exploded in my megasquirt. It is a 22 uF 25V cap.
The local hobby shop didn't have a 22uF tantalum capacitor above 16V so instead I picked up some electrolytic capacitors rated at 22 uF 100V (NEV22M100DC) for about $1 total - will I be able to expect similar performance from the electrolytic caps or should I order some Tantalum caps and wait for them to get to me?
I read that tantalum caps have a better ESR and volumetric efficiency - is there a layman's explanation of these two things?
Part that exploded:
Potential replacement part: NEV22M100DC - NTE ELECTRONICS - CAPACITOR ALUM ELEC 22UF, 100V, 20%, RADIAL | Newark element14 US
yay or nay?

Thanks guys, I ended up purchasing the 35V rated capacitor from digikey largely because 1. it is recommended by the mfg 2. electrolytic caps I bought have a rated operating life of about 1000 hours (@ average 40MPH = 40k miles) vs longer for the tantalum units.
