TLGE18T

The TLGE18T is a kind of LED lamp. It is designed for panel circuit indicator. There are some features as follows: (1) 5 mm diameter package; (2)InGaAlP technology; (3)all plastic mold type; (4)transparent lens; (5)high intensity light emission; (6)excellent low current light output; (8)applications: outdoor message signboards, safety equipment, automotive use, etc.

The following is about the maximum ratings (Ta=25) of the TLGE18T: (1)forward current (DC), IF: 50 mA; (2)reverse voltage, VR: 4 V; (3)power dissipation, PD: 120 mW; (4)operating temperature range, Topr: -40 to 100; (5)storage temperature range, Tstg: -40 to 120.

The last one is about the electric and optical characteristics (Ta=25) of the TLGE18T: (1)forward voltage, VF: 2.0 V typ and 2.4 V max at IF=20 mA; (2)reverse current, IR: 50A max at VR=4 V; (3)luminous intensity, IV: 272 mcd min and 700 mcd typ at IF=20 mA; (4)peak emission wavelength, P: 574 nm typ at IF=20 mA; (5)spectral line half width, : 17 nm typ at IF=20 mA; (6)dominant wavelength, d: 571 nm typ at IF=20 mA.
