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 = 10

Ω;101 = 100Ω;102 = 1,000Ω;

103 = 10,000

Ω;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.

GF281 Series

NOTE: FMS = From Mounting Surface
