This is what we need. Our problem is size. We need the smaller cap with this description - 22uF, <180V, Non Polarized - in order to develop a lower voltage circuit in AC net. In fact, we are trying to develop a mini circuit to suplly a LED (700mA). One of the ideas was use a capacitor to fall the AC voltage. Is possible to find this cap? Any other idea? Thanks!
