P103MU .01uf 10nf 1000V Ceramic Disc Capacitor (5 Pieces)

so here I've got some two capacitors on the left is a one microfarad 35 volt tantalum and on the right is a one microfarad 50 volt ceramic a multi-layer ceramic and they're about the same physical size and at the same capacitance and there are very similar voltage but the ceramic is a relatively new innovation certainly to have a ceramic of that high capacitance has only really occurred in the last few years tantalum have been around for much much longer and it's the mobile phone industry really that's brought along these high value ceramics because before they were available the only thing you could use really was a tantalum electrolytic switch is too big and frankly too unreliable and the price of tantalum started to go sky-high tantalum is a relatively rare metal and so there was a big push to get ceramic capacitors with these high values and because of the multi layering techniques
