NOTE:
1.Derate power dissipation linearly 1.70 mW/°C above 25°C ambient.
2.Derate power dissipation linearly 13.0 mW/°C above 25°C case.
3.RMA flux is recommended.
4.Methanol or isopropyl alcohols are recommended as cleaning agents.
5.Soldering iron tip 1/16” (1.6mm) minimum from housing.
6.As long as leads are not under any stress or spring tension
7.Total power output, PO, is the total power radiated by the device into a solid angle of 2 ! steradians.
