When using a capacity load such as a lamp, always connect a protective resistor (R=150
Ω)
serially to the load to suppress rush currents. (Make sure that the current is less than the above
tolerable current including the instantaneous current.)

CAUTION
When using an inductive load such as relays, always connect a diode in parallel to the
load as a noise countermeasure.
When using a capacitive load such as a lamp, always connect a protective resistor in
series to the load to suppress rush currents.
