The marking on these capacitors is 103Z. Z refers to the dielectric type. 103 is the capacitance value in picofarads (pF) where this is read as 1,0, followed by three zeros.
0.01uF = 10nF = 10,000pF

A ceramic capacitor is a fixed value capacitor in which ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. Single layer disc, resin coated with through-hole leads.
