Part Numbering System
RV Q 20 N 15 S B 103 M
NOTE: FMS = From Mounting Surface
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 = 10 Ω ; 101 = 100 Ω ; 102 = 1,000 Ω ; 103 = 10,000 Ω ; 104 = 100,000 Ω ). See table for standard resistance values. Resistance Taper: B = Linear. 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 Shaft, Right Angle Ear-Lug Terminals. Size: 20 = 20mm Diameter. Rotational Life: Q = Long Life, 1,000,000 cycles. TOCOS Series Name: RV = Carbon Film Element.
