{"product_id":"3mm-water-clear-white-led","title":"3mm Water-Clear White LED - Through-Hole","description":"\u003cdiv class=\"nznpd\"\u003e\n\u003cdiv class=\"nznpd__lead\"\u003e\n\u003cp class=\"nznpd__intro\"\u003eAn LED is a small light that runs from a low DC voltage. It only lights when current flows one way through it, so it has to go in the right way round, and it needs a resistor in series to set its current. This is a standard 3mm round-top through-hole LED with short legs, a water-clear lens and a cool white light. The clear lens looks colourless when off and throws a bright, focused beam when on, far brighter than a coloured indicator at the same current. For coloured 3mm LEDs with tinted lenses, see the \u003ca href=\"\/products\/3mm-led-diodes\"\u003e3mm diffused LEDs\u003c\/a\u003e in red, orange, yellow, green and blue.\u003c\/p\u003e\n\u003cp class=\"nznpd__intro\"\u003eUse it for power and status lights, a small lamp in a model, or a light behind a panel in a 3mm hole. The 2.54mm lead spacing plugs straight into a breadboard and fits standard 0.1 inch PCB pads. White needs about 3V itself, so it is brightest from 5V; on a 3.3V pin it still works with a small resistor but glows softer. Sold singly with a minimum of 10. Each LED needs its own resistor, which is not included; the \u003ca href=\"\/products\/metal-film-resistor-assortment-kit-600pc-30-values-10%CE%A9-1m\"\u003e600-piece resistor kit\u003c\/a\u003e has every value given below.

On 3.3V there is little voltage to spare, so use 47 ohm and expect a softer glow (about 2 to 6mA). If it is too bright for an indicator, a 1k resistor on 5V gives a gentle glow at about 2mA.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cdiv\u003e\n\u003cstrong\u003eWire it up\u003c\/strong\u003e\u003cp\u003eConnect the supply positive, or a board output pin, to the resistor, the resistor to the long lead, and the short lead to GND.
