Notes from Electrical Specifications Table
A. OCL (primary inductance) is measured at the primary winding. Turns ratio is specified primary:
secondary.
B. To make a 1CT:1 ratio from a 1CT:2CT ratio, use only one-half of the secondary (2CT) winding.
C. It is possible to use the same transformer model for the three impedance levels of T1 (100 W) and CEPT
(75
Ω & 120 Ω). For specific connection information and resistor values, refer to IC vendor’s data
book.
D. Dual Ratio Transformer (T1071NL and T1145NL) - These transformers have tapped secondary windings

E. Dual Ratio Transformer for the surface mount package is anti-static tubes. Optional Tape & Reel
packaging can be ordered by adding a “T” suffix to the part number, (i.e. T1064NLT).
F. Extended Temperature Range Models - For extended temperature range transformers (-40�C to +85�C
operating temperature range), OCL (Open Circuit Inductance) for the primary winding) is specified
at both -40�C and +25�C. At -40�C, OCL is 600
μH minimum. All other parameters are specified at +25�C
only. Standard temperature range is 0�C to +70�C.
to provide two turns ratios (T/R). Use the entire primary winding and connect the secondary pins
listed below to obtain desired turns ratio:
