  • 42T/44T/46T/47T/47TS series

  • YDS

ISDN-S0 Interface Isolated Telecom Transformer


Features


  • The pulse masks are easily realized due to adjusted leakage inductances.

  • Optimum common mode rejection of the output signal due to low coupling capactances.

  • The impedance masks are reliably fulfilled even during DC premagnetization.

  • High DC capability, therefore phantom power feeding is unproblematic.

  • Recognized by UL 60950-1 (47T/47TS).
