Why do capacitors have abbreviated markings?
The capacitors which are small in size does not provide space required for clear markings and only few figures can be accommodated in the given space in order to mark it and provide a code for their various parameters. Thus, abbreviated markings are used in such cases wherein three characters are used to mark the code of the capacitor.
