Notes:

(1)

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

(2)

Derate linearly 1.67 mW/°C above 25° C.

(3)

All parameters were tested using pulse techniques.

(4)

Leads are 0.20” square (5.080 mm) and 0.425” long (10.80 mm), minimum.

(5)

Methanol or isopropanol are recommended as cleaning agents. Plastic housing is soluble in chlorinated hydrocarbons and

ketones. Spray and wipe; do not submerge.

(6)

Polarity is denoted by color of housing top: LED (gray or clear), sensor (black).
