2 Ohms and in dropping resistor 2 Ohms, it could be expected that the magnetic field in the coil carrying current would be ~10 times higher with the switched dropping resistance than without it.
The magnetic field was excited by a pulsed current without a dropping resistor, and by a constant current with a dropping resistor (R = 2 Ohms).
5%, plus/minus 1%, and plus/minus 5%, making it ideal for use as a power supply bleeder resistor or series dropping resistor
in pulsing applications and voltage divider circuits.
Operation directly from a 3-volt or 5-volt supply with no dropping resistor
A dropping resistor
from the DC bus initiates start-up current for the IRIS4009.
Wide I/O Bus Enables Low Operating Frequency; Dropping Resistors
Reduce Power Draw
The low start-up current substantially reduces dissipation in any dropping resistors
required for start-up of the part, while the minimized operating current drastically cuts the amount of power that must be supplied to a SiP280x controller merely to power the IC.
The patented self-bias topology allows designers to easily integrate into single-supply, 5 Volt applications without the need for any external dropping resistors
