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; 103 = 10,000Ω; 105 = 1,000,000Ω ). See table for standard resistance values. Resistance Taper: B = Linear. A = CW Audio (logarithm). C = CCW Audio (logarithm). Shaft End Style: S = Slotted (standard for 15mm or 20mm shaft length). F = Flatted (special order for 20mm shaft length only ). Standard Shaft Length: 15 = 15 mm FMS. 20 = 20mm FMS. Up to 30mm shaft length available (special order). Style: N = Panel Mount, Single Unit, Single White Plastic Shaft, Right Angle Ear-Lug Terminals. Size: 20 = 20mm Diameter. TOCOS Series Name: RV = Carbon Film Element.
