I need to replace the following cap:
It was placed at the input of a device that runs off 24Vdc, like the following schematic.
I'm repairing the unit after an explotion due to a maintenance where the board was fed 220Vac instead of 24Vdc... Bottom line, while repairing the unit i found this Cap (C1) shorted and i need to replace it, but i've never seen a tantalum cap with this markings.
Of course, it's a 47uF cap, but the rest of the data i ignore.
I assumed that K is for tolerance (10%), and 20 for 20V, but this makes no sense in a circuit that runs on 24Vdc, so i need to find out the voltage rating of this cap (sure, i could simply replace it with a 40V and be safe, but i want to leave things as original as possible, and also want to learn to read this codes, it will become usefull in the future...)
So, could you fill the next list and perhaps explain how this code is selected?
