Ceramic capacitor is necessary to have a temperature that is greater than -55°C for stable operation.A substance's temperature coefficient of resistance is generally defined as how its electrical resistance changes with per degree change in temperature.A voltage of 50V can be used for operation.In a capacitor, the lead pitch is just the distance (spacing) between adjacent threads.
