Selfs - ISDN Common Mode Chokes - FAMILLE 46H14 46V15

DOUBLE 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 two-wire telephone line input and also at the power input of the network termination (NT)
