  • Always use current limit resistors when necessary
  • LEDs could be electrically connected in parallel, with each Correct current limiting resistor Product Specifications Circuit Design Notes

Manual soldering is suggested Suggested storage conditions: 25 °C +/-10°C (77°F +/-50°F), relative humidity 65% RH +/- 20% RH. - Use soldering irons of which power is less than 30 Watt. - Keep the temperature of soldering irons below 360 °C - Only one soldering is allowed on each bonding pad. - The maximum time from when a soldering iron comes into contact with the parts that are to be connected until the joint is finished should not exceed three seconds. - Perform other procedures after the soldered pad cools down.
