注释

Frequency at which the differential mode attenuation equals 3 dB.
Inductance is per winding.
DCR is per winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
For TRF 2000L, isolation (hipot) measured from pins 1,8 to 4,5 for one minute.
For TRF 4000L, isolation (hipot) measured from pins 1,2,7,8 to pins 3,4,5,6 for one minute.
