                                    0=100  1=101  2=102  3=103  4=104  5=105  6=106  J=10-1  K=10-2  L=10-3  M=10-4
        8.4.3 The 12th, 13th & 14th digits.
                    The 12th digit is to denote the Packaging Type with the following codes:
                                    C=Bulk in (Chip Product)               T=Tape/Reel
        8.4.4
The 13th digit is normally to indicate the Packing Quantity of Tape/Box & Tape/Reel packaging types. The following letter code is to be used for some packing quantities:
                                    1=1000pcs      2=2000pcs     3=3000pcs      4=4000pcs
                                    5=5000pcs      C=10000pcs   D=20000pcs     E=15000pcs
                                    Chip Product: BD=B/B-20000pcs   TC=T/R-10000pcs
        8.4.5

6﹜Power Rating
   
6.1 Voltage rating:
    Resistors shall have a rated direct-current (DC) continuous working
    Voltage or an approximate sine-wave root-mean-square (RMS) alternating-current (AC) continuous working voltage at commercial-line frequency and waveform corresponding to the power rating, as determined from the following formula:

RCWV =

    Where: RCWV= Rated dc or RMS ac continuous working voltage at commercial-line frequency and waveform (VOLT.)
              P = power rating (VATT.)            
              R = nominal resistance (OHM)
    In no case shall the rated dc or RMS ac continuous working voltage be greater than the applicable maximum value.
    Resistors shall have a power rating based on continuous load operation at an ambient temperature of 70. For temperature in excess of 70, the load shall be derate as shown in figure 1
