Help with capacitor idenification please

Can you help me work out the values of these two capacitors?

The first capacitor is much bigger than the second. Can you make a very approx guess at the VOLTAGE RATING of the capacitors?

Thanks!

** You have the pics reversed - d*****ad.

The smaller cap is a 100nF ( 0.1uF ) ceramic - probably 50 volt rated.

The larger cap is a 470nF ( 0.47uF ) polyester, 10% tolerance, rated at 630 volts DC.

Oops! You're dead right, my pics are reversed.

Thanks for the ID info. Much appreciated.

One other point - the information on the device is important. When asking for assistance, use pictures taken from a perspective that shows the printing on the device.

This is a good reference:

104 = 10 x 10^4 pF = 0.1uF F474K = 47 x 10^4 pF = 0.47uF +/- 10% 630 MPP = 630V Metallized Polypropylene Film Capacitor

The voltage ratings can often be deduced from an understanding of the application.

Very likely and the cheapest type you can buy.
