Sufficient evaluation of transient power supply fluctuation and overcurrent protection function with
the actual application is needed to determine the proper constants. Contact our sales office in case
the constants should be set to other than 47 µF • Ω.

guarantee proper operation. Perform thorough evaluation using an actual application to set the
constant.
