GF04 Series
GF04 W 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. Terminal Style: W, U = 3-Lead Configurations, Top Adjust. S, V = 3-Lead Configurations, Side Adjust. TOCOS Series Name.
