Part Numbering System
Resistance Tolerance: K = 10% 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; 105 = 1,000,000Ω ).
Resistance Taper: B = Linear.
Packaging: T = Tape & Reel; Blank = Bulk.
Terminal Style: W = J-Hook Top Adjust.
J = J-Hook Side Adjust.
G = Gull-Wing Side Adjust.
