(Note 1)
When using an inductive load such as a relay, always connect a diode (voltage resistance
100V or more, 100mA or more) in parallel to the load.
(Note 2)
When using a capacitive 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 momentary current.)
