RV 20 103 MN2 SK B20
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;
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: SK = Knurled and Slotted.
Standard Shaft Length: 15 = 15mm FMS.
Style: N2 = Panel Mount, Single Unit, Knurled Black Plastic Shaft,
Right Angle Ear-Lug Terminals.
Size: 20 = 20mm Diameter.
TOCOS Series Name: RV = Carbon Film Element.
