Resistance Tolerance: M = 20% standard.
Resistance Code: Expressed in ohms. A three digit code where the first two digits
are significant figures, and the third digit indicates the number of zeros that follow
these figures (i.e., 100 = 10Ω; 101 = 100Ω; 102 = 1,000Ω; 105 = 1,000,000Ω ).
Resistance Taper: B = Linear.
Terminal Style: Through-Hole where C = Top Adjust; CF = Bottom Adjust.
