42T/44T/46T/47T/47TS Series ISDN-S0 Interface Isolation Transformer
Product Description
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).
