Notes:

(1)

Measured with input and output leads shorted in air with a maximum relative humidity of 50%. If suitably encapsulated or oil-immersed, the

isolation voltage is increased to 25 kV minimum.

(2)

UL recognition is for 15kV dc for one minute.

(3)

RMA flux is recommended. The duration can be extended to 10 seconds maximum when flow soldering.

(4)

Derate linearly 2.0 mA/°C above 25°C.

(5)

Derate linearly 2.67 mW/°C above 25°C.

(6)

Derate linearly 3.33 mW/°C above 25°C.
