Note 2.

The capacitance of an electrolytic capacitor decreases at a low temperature (0 ˚C or lower). Determine

the capacitance of the capacitor to be used taking this into consideration when the µPD4711B is used at

a low temperature. Keep the wiring length between the capacitor and IC as short as possible.
