All transformers listed on this data sheet are UL1459, UL1950, CS950 approved per Underwriters Laboratories – file E133523, Reinforced
Insulation.
The dual packages contain transmit and receive transformers side by side, sufficient crosstalk attenuation is achieved by the inherent
characteristics of the toroid cores as well as by their proper positioning. The crosstalk attenuation is typically 55 dB or better from 100 kHz to
10 MHz. This result was established with the test circuit shown here:
The “high-frequency” 4-line common mode chokes, in the chart below, provide an effective means of compliance with national and interna-
tional regulations on EMI. They are designed to be used in conjunction with Pulse’s T1/CEPT transformers. Crosstalk is typically – 70 dB at
1 MHz and – 55 dB at 10 MHz.
