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).
