characteristic of the particular inductive device. See the table on page 2-7 for
recommended suppressors.
For inductive dc load devices, a diode is suitable. A 1N4004 diode is acceptable for
most applications. A surge suppressor can also be used. See the table on page 2-7
for recommended suppressors.
As shown in the illustration below, these surge suppression circuits connect directly
across the load device.
