104 SERIES

      104 series have five features.The first one is that material conforms to UL94 V-O flammability ratings.The second one is about bi-colour options available.The third one is about reverse polarity options available.The fourth one is about product illustrated 104-505-04.The last one is about typically available ex stock.
      In part number 104-505-04,Colour is red.Lens is colour diffused.Vopr(voltage DC) is 2.0Vdc(voltage DC for 20mA product is Vf@20mA, not Vopr).lopr(current DC) is 20mA.lv@20mA ( luminous intensity) is 60mcd.p(wave length)is 627nm.Topr(operating temp) range is from -40 to +85(products must be derated according to the derating information. Each derating graph refers to specific LEDs).Tstg(storage temp) range is from -40 to +85.Housing material of 104 series is polycarbonate.This material offers UL94 V-0 flame retardancy(material test thickness 1.6mm) and a high impact strength. This material has a melt point of 290-340°C and is suitable for use in the majority of automatic soldering processes.The long lead of a non-cropped unit can also be used to help identify the anode. For the 2 pin Bi-colour units the standard colour configuration is red anode to the "+" sign.Reverse polarity is offered on all PCB units, with the exception of the 125 series.Multiple units can also be supplied in reverse polarity but not with mixed polarities.The supply must be reversed to achieve the second colour for a 2 pin Bi-colour unit, standard colour configuration for these units is red anode to the "+" sign.
