Ceramic capacitor is important to maintain the operating temperature above -55°C if you want stable operation.Its coefficient is 30 ppm/°C and determines the change in resistance per degree of temperature for a substance.With the voltage 200V, it is capable of operating.Lead pitch of a capacitor is simply the distance (spacing) between adjacent threads, and its pitch is 2.54mm.
