2Typically, open circuit test voltage is 2.0 V and short circuit current is <0.6 mA.
3Specifications do not include errors due to test lead capacitance and capacitance floor (may be up to 1.5 nF in the 40 nF range).
4Typical means when the frequency is at 50 Hz or 60 Hz and the duty cycle is between 10 % and 90 %. |
