NOTES
NOTES: 1. Dimensions for all drawings are in inches (millimeters). 2. Tolerance of .010 (.25) on all non-nominal dimensions unless otherwise specified. 3. Lead cross section is controlled between .050 (1.27) from the seating plane and the end of the leads.
1. Derate power dissipation linearly 1.67 mW/C above 25C. 2. Derate power dissipation linearly 2.50 mW/C above 25C. 3. RMA flux is recommended. 4. Methanol or isopropyl alcohols are recommended as cleaning agents. 5. Soldering iron 1/16" (1.6mm) from housing. 6. As long as leads are not under any stress or spring tension.
