| CQX14, CQX16 GaAs INFRARED EMITTING DIODE PACKAGE DIMENSIONS 0.209 (5.31) 0.184 (4.67) DESCRIPTION The CQX14/16 are 940 nm LEDs in a narrow angle, TO-46 packages. 0.030 (0.76) NOM 0.255 (6.48) FEATURES * Good optical to mechanical alignment 1.00 (25.4) MIN ANODE (CASE) * Mechanically and wavelength matched to the TO-18 series phototransistor * Hermetically sealed package SCHEMATIC ANODE (Connected To Case) CATHODE 3 0.100 (2.54) * High irradiance level 0.050 (1.27) * European "Pro Electron" registered 1 1 0.040 (1.02) 0.040 (1.02) 45 3 O0.020 (0.51) 2X NOTES: 1. Dimensions for all drawings are in inches (mm). 2. Tolerance of .010 (.25) on all non-nominal dimensions unless otherwise specified. 1. Derate power dissipation linearly 1.70 mW/C above 25C ambient. 2. Derate power dissipation linearly 13.0 mW/C above 25C 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.
