You can find Large Range of 4V polar capacitors.
Polar capacitors are ideally suited for a DC power supply ripple filter. When connected in wrong polarity, chemical reactions within a polar capacitor can cause them to blow up. Polarized capacitors is also known as electrolytic or polar capacitors.

EVE-eVision Electronics has large range of polarized capacitors with almost all the voltages.
