SMD LED red SMD lights with LED

The meaning of electrical parameters

(1) Forward working current If: It refers to the forward current value when the light-emitting diode normally emits light. In actual use, you should choose IF below 0.6?IFm according to your needs SMD LED0805 red light.

(2) Forward working voltage VF: The working voltage given in the parameter table is obtained under a given forward current. It is generally measured when IF=20mA. The forward working voltage VF of the light emitting diode is 1.4~3V. When the outside temperature rises, VF will drop Red Light Emitting Diode.

(3) V-I characteristics: the relationship between the voltage and current of the light-emitting diode

When the forward voltage is less than a certain value (called the threshold), the current is extremely small and no light is emitted. When the voltage exceeds a certain value, the forward current increases rapidly with the voltage, and light is emitted. From the V-I curve, the forward voltage, reverse current and reverse voltage parameters of the luminous tube can be obtained. The reverse leakage current IR of the forward luminous tube is less than 10μA Patch Light Emitting Diode.
