A. OCL (primary inductance) is measured at the primary winding.
(Level One) LXT 304/305/307 T1,E1 T1065 T1105
Turns ratio is specified primary: secondary. (CT = Center Tap).
LXT 304/305/307 T1 T1070 T1110
B. To make a 1CT:1 ratio from a 1CT:2CT ratio, use only one-half
LXT 304/305/307 75E1,120E1 T1071 T1111
of the secondary (2CT) winding.
LXT 310/317/318 T1068 T1108
C. It is possible to use the same transformer model for the three
LXT 331 T1,E1 T1068 T1108
impedance levels of T1 (100) and CEPT (75 & 120). For
LXT 331, LXT 332 T1065 T1105
specific connection information and resistor values, refer to IC

turns ratios (T/R). Use the entire primary winding and connect
LXT 336 T1065 T1105
the secondary pins listed below to obtain desired turns ratio:
