153 SERIES

      The 153 series are designed as PCB mounting leds with diameter of 3mm surface mount whose pack quantity is 250 pieces.
      This 153 series have five features.The first one is that it would be compatible with surface-mount soldering techniques.The second one is that its housing conforms to UL94 V-0 flammability ratings.The third one is that the 153 series would have easy fitting and polarity identification.The fourth one is products illustrated 153-311-04.The last one is that it would be typically available ex stock.That are all the features.
      Some typical technical characteristics (Ta = 25°C) of the 153 series have been concluded into several points as follow which should be noted that mean time between failure would be 100,000 hours and luminous intensity figures refer to the unmodified discrete LED.For 153-305-04,its colour would be red. The lens of the 153 series would be colour diffused.Its voltage DC would be 2.0Vdc. The current DC of the 153 series would be 20mA.Its luminous intensity would be 40mcd.Its wave length would be 627nm.Its operating temperature would be from -40 ~ +85°C.Its storage temperature would be from -40 to +85°C. The 153 series  would also be RoHS compliant.For 153-311-04,its colour would be yellow.Its lens would be colour diffused.Its voltage DC would be 2.1Vdc. The current DC of the 153 series would be 20mA.Its luminous intensity would be 30mcd.Its wave length would be 590nm.Its operating temperature would be from -40 ~ +85°C.Its storage temperature would be from -40 to +85°C. The 153 series  would also be RoHS compliant.For 153-314-04,its colour would be green.Its lens would be colour diffused.Its voltage DC would be 2.2Vdc.Its current DC would be 20mA.Its luminous intensity would be 40mcd. The wave length of the 153 series would be 565nm.Its operating temperature would be from -40 ~ +85°C.Its storage temperature would be from -40 to +85°C.It would also be RoHS compliant.For 153-330-04,its colour would be red/green.Its lens would be white Diffused.Its voltage DC would be 2.0/2.2 Vdc.Its current DC would be 20mA. The luminous intensity of the 153 series would be 20/16 mcd.Its wave length would be 627/565 nm.Its operating temperature would be from -40 ~ +85°C.Its storage temperature would be from -40 to +85°C.It would also be RoHS compliant.
