Hi Diyahnih

With these types of numbers, the first two digits signify the value of the component; the third digit signifies how many zeros follow the value.

The parts are rated in pF (mmF or uuF). Here is how the parts in your kit break down:

152 = 1500 pF = .0015uF
103 = 10000 pF = .01 uF
503 = 50000 pF = .05 uF
104 = 100000 pF = 0.1 uF
204 = 200000 pF = 0.2 uF

The "0.25 ufk" and "0.05 ufk" should be equal to 0.25 uF and 0.05 uF.

And, finally, uF = mfd.
