J Series, Blue & White LEDs, Water Clear LED, 4251 J Series T-1 3/4, 5mm Round, Hi-Efficiency 0.5 The J series lamps are made with AlInGaP chips which can be used for standard brightness at low current (2mA) or super brightness at standard current (20mA). The Blue LEDs are made with GaN/SiC (428nM) and InGaN/SiC (468nM) chips. The White LEDs are made with GaN chips. Blue and white should only be used when these colors are necessary for the application and higher cost is acceptable. Please note the long lead is the anode. 5.0±.2 2.54 1.0 min 1.0±.2 5.9±.3 8.6±.3 26.4 min GENERAL INFORMATION Operating Temperature Range Storage Temperature Range Reflow Soldering Temperature -30 °C to +85 °C -55 °C to +100 °C 260 °C for 5 sec max APPLICATION INFORMATION (ALL RATINGS AT 25 °C AMBIENT) Peak Part No. Emitted Color λ Absolute Maximum Ratings ∆λ Pd If (mA) Ir E/O Characteristics Iv (mcd) @If=20mA Vr Vf (V) @ If=20mA 2Θ1/2 (nM) (nM) (mW) dc 1/10 duty @ 1 khz @Vr=5V (µA) (V) 2mA Min Typ Min Typ (Deg) JRC4251 Red 632 20 60 25 160 10 5 50 340 890 2.0 2.4 10 JGC4251 Green 575 20 60 25 160 10 5 14 230 340 2.0 2.4 10 JGC4251-2 Green 575 20 60 25 160 10 5 14 450 620 2.0 2.4 10 JYC4251 Yellow 591 15 60 25 160 10 5 61 410 1080 2.0 2.4 10 JOC4251 Orange 621 18 60 25 160 10 5 65 430 1150 2.0 2.4 10 JDC4251 DeepRd 650 20 60 25 160 10 5 38 370 630 2.0 2.4 10 JYOC4251 YelOrng 611 17 60 25 160 10 5 64 420 1110 2.0 2.4 10 IUBC4251 Blue 428 65 140 25 70 50 5 - 250 400 3.8 4.5 10 IUBC4251-7 Blue 468 26 120 25 - 50 5 - 400 630 3.5 4.0 10 IUWC4251 White - - 120 25 100 10 5 - 1300 1700 3.6 4.0 20 Specifications subject to change without notice.
