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., 200 = 20Ω; 201 = 200Ω; 202 = 2,000Ω;
203 = 20,000Ω ). See table for standard resistance values.

Specify taper and resistance code as shown.
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: B203A503 or if both units are the same: B203X2
