■ Precautions for use
(1) This document provides the BOM for evaluation boards. Small parts can also be selected for resistor, and capacitor.
(2) When miniaturizing a resistor, consider decrease in rated power and withstand voltage.
(3) When miniaturizing a ceramic capacitor, consider decrease in withstand voltage. In addition, the capacity may be
decreased by DC bias characteristics, and the desired characteristics may not be obtained.
(4) If ceramic capacitor models differ even when they have the same capacity and withstand voltage, the capacity may be
decreased by DC bias characteristics depending on the model, and desired characteristics may not be obtained. Be sure to
check the DC bias characteristics.
(5) This circuit constant is the value for our evaluation board. It may be necessary to adjust the constant for the actual board.
Carry out suitable evaluations.
