Soldering temperature: 260C max; Soldering time: 3 sec. max; Soldering portion of lead: up to 2 mm from the body of the device. 2. The lead can be formed up to 5 mm from the body of the device without forming stress. Soldering should be performed after the lead forming. 26 Purdy Electronics Corporation * 720 Palomar Avenue * Sunnyvale, CA 94086 Tel: 408.523.8200 * Fax: 408.733.1287 * email@purdyelectronics.com * www.purdyelectronics.com 2.54 0.06 Green Cathode 0.5 square x 2 1/5/98 AND2451RGL Dual Color Standard Bright LED Lamps Red 50 30 Forward Current IF (mA) 20 10 5 3 2 1 1.7 TA = 25C IF vs. VF 50 30 Forward Current IF (mA) 20 10 5 3 2 Green IF vs. VF TA = 25C 1.8 1.9 2.0 2.1 Forward Voltage VF (V) 2.2 2.3 1 1.7 1.8 1.9 2.0 2.1 Forward Voltage VF (V) 2.2 2.3 IV vs. IF 5 Relative Luminous Intensity IV Red (R) 5 Relative Luminous Intensity IV Green IV vs. IF 2 1 0.5 2 1 0.5 0.2 0.1 1 2 5 10 20 50 0.2 0.1 1 2 5 10 20 50 Forward Current IF (mA) This graph shows relative luminous vs. forward current.
