Part Numbering System
Resistance Tolerance: K =
10%; M =
20%
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.
Adjustment Knob: K 2 = Permanent Large Knob, Extended Shaft.
Blank = No Knob, Single-Slot, Short Shaft.
