11 Unless other specified in the acquisition document, the first two code elements shall represent the first and second digits of the electrical characteristic value.

21 Except as specified in Appendix I, the third code element shall represent the factor by which the two digits are to be multiplied to complete the characteristics value identification.

31 The tolerance value shall be identified by one code element as shown in table II.

41 The product level designator symbol shall be identified by the last code element. (NOTE: This identification marking shall be applied only when authorized by DoD specifications.)

51 Body color shall indicate the tolerance for coils.

61 Value as specified in the acquisition document.

71 Not applicable to coils (see Appendix I).
