Test Condition
VR = 32 V
VR = 32 V , Ta = 60 °C
VR = 1 V , f = 1 MHz
VR = 10 V , f = 1 MHz
VR = 30 V , f = 1 MHz
C1 / C30
VR = 5 V , f = 470MHz
VR = 1~ 30V
* A set of HVU314 is of uniform C-V characteristics.
Measure max. value and min. value of capacitance at each bias point of VR=1V and 30V.
Calculate Matching Error,
(Cmax-Cmin)
∆C/C=
