Hi all,
I've got a Superbright LED, and I do mean bright.. now Im not new to series resistors to leds... but a tad unsure of this one, I rang the supplier of the LED.. ok and "What I thought of the answer was not right well not in my eyes.. a complete idiot who ever worked in the Technical dept of the Store in question...
I want to put 9Volts into the led with the series resistor, otherwise the battery will kill the LED as "you all know that" Now what I've worked out from the specs of the LED in question.. & worked out that between 100-400 ohms would be ok...
Here's the Specs of the LED
Power dissipation 130mw
Peak forward current = 100ma
Continuous forward current :50ma
Derating factor: 0.4ma
Reverse voltage 5V
======================================================
forward voltage min 2.3v Max 2.6v
Luminous Intensity lv min 2500 max 7200mcd
Dominant Wavelength 625nm
Spectrum Radiation Bandwidth 20nm
Reverse current lr 10ua
Viewing angle 30degrees
-----------------------------------------------------------------------
So thats the Specs, in case you asked...
So am I right with my resisitor Value..
thanks for reading this.. !!
