GF281 Series
Part Numbering System
GF 281 G L 15 S B 103 K
NOTE: FMS = From Mounting Surface
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;
103 = 10,000Ω; 105 = 1,000,000Ω ). See table for standard resistance values.
For Single Unit:
Specify taper and resistance code as shown.
For Ganged Tandem Unit:
Specify a taper code and resistance code for each unit starting with
the front unit followed by the rear unit. If both units have the same taper
and resistance codes, add “X2” suffix per example below.
Examples: B103A503 or if both units are the same: B103X2
Resistance Taper: B = Linear.
Shaft End Style: S = Slotted.
F = Flatted.
R = Round.
Standard Shaft Length: 15 = 15 mm FMS.
20 = 20mm FMS.
Up to 50mm shaft length available (special order ).
Shaft Lock: L = With Shaft Lock.
Blank = Without Shaft Lock.
Style: Blank = Panel Mount, Single Unit, Single Shaft, Right Angle
Ear-Lug Terminals.
G = Panel Mount, Ganged Tandem Unit, Single Shaft,
Right Angle Ear-Lug Terminals on Each Unit.
Size: 281 = 28mm Diameter.
TOCOS Series Name: GF = Cermet Film Element.
