IEC 60062:2004 specifies marking codes for resistors and capacitors and indexes for the dielectric material and the electrodes of plastic film and paper capacitors. This edition includes the following significant technical changes with respect to the previous edition:
a) completion of the existing code systems for
- resistors with a three-character code system and a four-character code system;
- temperature coefficient of resistance with a letter code system;
- data code system for capacitors and resistors with the 10-year cycle code (two-character code), the 20-year cycle code (four-digit code), the 10-year cycle code (four-digit code), and a one-character code - four-year cycle.
b) extension with a code letter system for the dielectric material of plastic film and paper capacitors.
