RJC26 Series
RJC26 X B 102 K
Part Numbering System
Resistance Tolerance: K = 10%; M = 20%; Blank = 30%, 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 Ω ; 101 = 100 Ω ; 102 = 1,000 Ω ; 105 = 1,000,000 Ω ). Resistance Taper: B = Linear. Terminal Style: W = 3-Lead Configuration, Top Adjust. X = 3-Lead Configuration, Side Adjust. TOCOS Series Name.
