(1)Care should be taken when selecting the capacitor, due to its tolerance, as well as the
parameter dependency on temperature, DC bias and frequency in addition to other factors.
The parameter maximum value must be respected for the full application range.
(2) To calculate PDmax(TA), use the formula PDmax = (TJmax - TA)/ΘJA (see Thermal
characteristics ) with the value for TJmax given in the current table and the value for ΘJA
given in Thermal characteristics.
(3) Refer to Thermal characteristics.
(4)This frequency of 1 MHz as a condition for VCAP parameters is given by design of the
internal regulator.
