LED 0402 cold white with enamelled copper wires (2 pieces)

(SKU.4-32002/p2) Pair of high brightness LED diodes measuring 1×0.50 mm wired with pre-soldered enamelled copper wires diameter 0.1mm.
With cold white light emission.
For their operation it is essential to use a resistor of approximately 1000 ohm connected in series to one of the power supply poles.
LED diodes can have different colored wires: red-positive and copper-negative, or have both copper-colored wires, in this case the positive is the longest wire.
