224 | capacitance in pico farads - first two digits are significant digits, third digit is the number of digits that follow. In this case: $$22 + 0000 = 220,000 pF = 0.22 µF$$ |
K | tolerance, F = ±1%, J = ±5%, K = ±10%, etc. |
600V | voltage rating (600 volts in this case) |
9644 | date code (44th week of 1996 in this case) |
