Part Numbering System for Surface Mount VG026 and VG039N
VG 026 CH XT B 102
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. Packaging: XT = Tape; Blank = Bulk. Design Type: Surface Mount Chip. Size: 026 = 2mm; 039N = 3mm (See Dimensions). TOCOS Series: VG = Cermet.
