capacitor voltage values (wv and v)

[soundhack]

The filter capacitors in my combo are marked as "450 WV" (sakura). I understand that WV is continuous voltage (as opposed to peak voltage). If I have a replacement cap that is just rated for volts ("450 V" on the can - nichicon), does the voltage rating refer to continuous voltage?

Thanks...

Yes and no, depends how the manufacturer defined it the datasheet. To be on the safe side interpret it as operating DC + peak value of any ripple that is present, especially when using the cap in rectifier ripple filter application.

thanks - i looked at the nichicon data sheet, and it showed a higher ripple than 450v. the caps are in, voltages are good, and it seems to be running fine.
