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 3750 VAC to 100° C.

(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 mA/°C above 25°C.

(6)

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