Hi everyone,
I am building a small dc to dc buck regulator circuit and the schematic shows either 1 of 330uF Tantalum or 2 parallel 220uF Tantalums.
My problem is that I can't get hold of either locally or even from the suppliers I often use on the net (Rapid)!
I wondered if there was a specific reason why Tantalums were used and if I could substitute another type, say an electrolytic maybe?
The design says the tantalums should be at least 3 volts which is very small in terms of voltage for most other types of caps, so maybe this is a factor in using them?
If anyone has any info or ideas on this I would be very grateful
Thanks for looking...........Al
