The Soldering Temperature is 260±5℃ and Soldering Time should be less than 3 sec, and soldering iron power should be less than 30W. Storage the products under the condition :temperature ( 25℃ ± 10℃ ) and humidity (65℃ CRH☒0℃ CRH) our recommendation. Storing the units in bad condition will cause the reflector sheet and decrease it’s adhesive power. The product working current must not more than the 60% of the Ifm or Ifp according to the working temperature.

* For operation above 25℃, The Ifm Ifp & Pd must be derated, the Curent derating is –0.36mA/℃ for DC drive and -0.86mA/℃ for Pulse drive, the power dissipation is -0.75mW/℃. * Lead Sodering Temperature:260℃ for 3 seconds Common cathode means that the cathodes of all of the LEDs are common and connected to a single pin.

Buy Common Cathode 12 Pin 3 Bit 1.48 x 0.75 x 0.31 Inch 0.55 Red LED Display 3pcs from Walmart Canada. So, it Suitable for people who is newbie of electronic. It is compatible with bread board and can work with Arduino by adding some current limiting resistors.

The advantage of 16 segment is that you can not only display 1234567890, but also ABCDEFGHIJKLM. Learn about 7 Segment Display along with its Working, Difference between Common Cathode & Common Anode, Pinout, Wiring, Library, Code & Arduino Project. This is a 16 segment common cathode LED and is red.

Exact dimensions are provided in the image below. As the result, the power transistor drive the high voltage (which is same voltage with Vs) and turn on the common cathode single digit 7 segment. 7 Segment LED Display - RED - SP5503 - Common Cathode - 14mm (0.56 Inch) This is a standard 0.56 inch (14mm) common cathode seven segment display. When there is the signal given at the input, the transistor 2N3904 will turned on and trigger the power transistor BD140. The basic concept of this kit was using two type transistors to amplify the voltage of seven segment. It can amplify the input signal to bigger voltage (Vs) subsequently drive the large common cathode single digit 7 segment. Only make one GND pin ground leave the other empty because both the GND pins are shorted. This kit able to drive the voltage in range 5V to 30V.

This kit is designed to drive a large size of common cathode single digit 7 segment.
