TERMINAL WIRE AND WINDING S = Solderable, inductive N = Solderable, noninductive W = Weldable, inductive (1) Z = Weldable, noninductive (1)

RESISTANCE VALUE 3 digit significant figure, followed by a multiplier 49R9 = 49.9 1000 = 100 1001 = 1000

TOLERANCE CODE B = 0.1 % D = 0.5 % F = 1.0 %

FAILURE RATE M = 1.0 %/1000 h P = 0.1 %/1000 h R = 0.01 %/1000 h S = 0.001 %/1000 h

PACKAGING CODE B12 = Bulk pack S70 = Tape/reel (smaller than 5 W) S73 = Tape/reel (5 W and higher) BSL = Bulk pack, single lot date code RSL = Tape/reel, single lot date code
