Selfs - ISDN Common Mode Chokes - FAMILLE 47H14 47V15
| QUAD CHOKES | Voltage 80 VDC/42 Vac Current 0.3 A |
These current-compensated chokes for data and signal lines are fitted with high-permeability toroid
core (ferrite). They are used in ISDN equipment in order to suppress the radio frequency interferences
(RFI) at the four-wire telephone line input and also at the power input of the network termination (NT)
and terminal equipment devices (TEs).
