Application Notes
A. OCL (primary inductance) is measured at the primary winding. Turns ratio is specified
B. To make 1CT:1 ratio from 1CT:2CT ratio, use one-half of the secondary (2CT) winding.
C. It is possible to use the same transformer model for the three impedance levels of T1
D. Dual Ratio Transformers — These transformers have tapped secondary windings to pro-

formers side by side, sufficient crosstalk attenuation is achieved by the inherent char-
acteristics of the toroid cores as well as by their proper positioning. The crosstalk
attenuation is typically 55dB or better from 100kHz to 10MHz. This result was estab-
lished with the test circuit shown below.
below provide an effective means of compliance with national and international regula-
tions on EMI. They are designed to be used in conjunction with Pulse’s T1/CEPT
transformers. Crosstalk is typically – 70db at 1MHz and – 55dB at 10MHz.
