Holding Current (I
H
)
Because FCC Part 68.306.A.6.iii specifies that registered terminal equipment not
exceed 140mA of DC current per conductor under short circuit conditions, the holding
current of the SIDACtor is set at 150mA.
For specific design criteria, the holding current (I
H
) of the SIDACtor must be greater
than the DC current that can be supplied during an operational and short circuit
condition.
Off-State Capacitance (C
O
)
Assuming that the critical point of insertion loss is 70% of the original signal value, the
SIDACtor can be used in most applications with transmission speeds of up to 30MHz.
For transmission speeds greater than 30MHz, a compensation circuit may be required.
