Note: Use a varistor as a protective circuit against reverse surge connected parallel to the coil. The reverse blocking voltage

should be about 3 times the value of the power source voltage.

* Minimum switching loads mentioned above are reference values. Please perform the confirmation test with actual

load before production since reference values may vary according to switching frequencies, environmental contions

and expected reliability levels.
