Defines the current-limit and the internal biasing currents. A
smaller/bigger value increases/decreases the current limit. It
will also effect power supply currents.
Defines with an internal resistor the delay time (a typical value
is 20 msec) from the low pass filter, whose output signal is
called ‘APFI’. Short disturbances will therefore be filtered. A
smaller/bigger value decreases/increases the delay time.
Defines with an internal resistor the corner frequency from a
high pass filter. It is used to make sure that longitudinal
disturbances (AC) will not produce a current limiting effect. A
smaller/bigger
frequency.
These resistors limit the peak currents during lightning
transients. The maximum value for these resistors is defined
by the allowed voltage drop on the resistors.
The AC-signal-current will be shunted by this capacitor.
