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. F = Flatted. R = Round. Standard Shaft Length: 10 = 10 mm FMS. 15 = 15 mm FMS. 20 = 20mm FMS. Up to 30mm shaft length available (special order ). Style: N = Panel Mount, Single Unit, Single Shaft, Rear Exit Vertical Lug Terminals, 3-Lug Triangular Pattern. L = Panel Mount, Single Unit, Single Shaft with Shaft Lock, Rear Exit Vertical Lug Terminals, 3-Lug Triangular Pattern. P1 = PCB Mount, Single Unit, Single Shaft, Rear Exit Vertical Mount Pin Terminals, 3-Pin Triangular Pattern. Operating Temperature Range: Y = 10C to 85C. Size: 20 = 20mm Diameter.
