Direct-to-board lead-free elements (SMD) are becoming more and more popular at the. There are several ways to determine the pin assignment of a light-emitting element. Suggetion to use resistor based on brightness requirmets. 1 'ZD2005 9061 smd led yel 40mcd gullwing pk10' The above description is all I have to identify a smd led I bought from jcar australia in an otherwise nondescript packet of ten. For normal operation, the anode and cathode of the LED must be connected to the respective poles of the voltage source according to the circuit diagram. If the LED lights up, this means you have a common anode LED. Then, place the black tip on one of the other leads. There are definitely manufactures that do NOT follow this scheme like this one from CREE. Place the red multimeter tip on the longest LED lead. SMD LEDs normally have some kind of marking like the following image from here indicates: The site states The CATHODE lead is always the lead to be identified with ALL LEDs, including surface-mount LEDs. Put you multimeter is in continuity mode. Lead time is about 5-7days after payment have been confirmed.Īnswer: Yes, only to pay shipping cost, free samples would be sent for testing. Just like the other LEDs SMD LED has two pins, anode and cathode for powering the LED. The best way to distinguish between a common cathode and common anode RGB LEDs is using a multimeter. Then make payment as the way you like, as soon as the payment have been confirmed, we will arrange shipment.Īnswer: If there is any quality problem or question, we could offer technical support or return service.Īnswer: about 15-20 days For in-stock products. Sometime the diode symbol creates confusion too.Identifing a LEDs the cathode and anode of a led is very easy by looking inside. After the order have been confirmed the invoice will be sent for reference. Luminous intensity:100-120mcd/50-60mcd/60-70mcdįorward voltage:2.8-3.2V/ 1.8-2.3V/1.8-2.3VĮmitting colors: available in red, blue, yellow green, pure green, pure white, amber, and orangeĪnswer: Yes, our parts could accept any kinds of testing, if there is any quality problem we will take responsibility.Īnswer: Within one year after package have been received.Īnswer: We could accept TT, Escrow, Paypal. Ultra Green /Red / White / Orange Color 0.56inch 4 Digit SMD LED Display Common Cathode For Digital Timer Indicator
