RJC07R Series
RJC07R K2 B 102 K
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 = 10; 101 = 100; 102 = 1,000; 105 = 1,000,000 ). Resistance Taper: B = Linear. Adjustment Knob: K 2 = Permanent Large Knob, Extended Shaft. Blank = No Knob, Single-Slot, Short Shaft. TOCOS Series Name.
