Its unique optical package enables designers to utilize fewer LEDs while achieving superior lighting performance. 0.020 (0.50) 0.212 (5.38) 0.188 (4.78) 0.069 (1.75) 0.053 (1.35) 0.033 (0.85) 0.026 (0.65) 0.024 (0.60) 0.008 (0.20) TYP. NOTES: 1. Dimensions for all drawings are in inches (mm). 2. Lead spacing is measured where the leads emerge from the package. 3. Protruded resin under the flange is 0.059" (1.5 mm) max. 4. All tolerances are 0.10" (0.25 mm) unless otherwise specified.
