    depends on the manufacturer ?
    103 is the value = 0.01 uF
    the J is the tolerance = ± 5%

    some manufacturers will underline the text, this indicates a 50/100V rated cap
    is your one underlined ?

    if not underlined then the 2A indicates a 100V rating

    Thanks for the info. I will assume it's in the 50/100V range. It's not underlined. I don't know the manufactur.
