{"product_id":"5mm-diffused-led-diodes","title":"5mm Diffused LEDs - Yellow or Blue Tinted Lens","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 low-voltage DC, such as the 3.3V or 5V on an Arduino, ESP32 or Raspberry Pi, with a resistor in series to set the current. These are standard 5mm round-top through-hole LEDs with diffused lenses tinted in their own colour, in yellow and blue. The tinted lens shows its colour even when the LED is off, so they are easy to pick out of a parts tray, and the light spreads through the lens for an even glow that reads well from the side. For a clear lens and a brighter, focused point of light, see the \u003ca href=\"\/products\/5mm-super-bright-water-clear-led-bulbs\"\u003e5mm water-clear LEDs\u003c\/a\u003e in red, green and white.\u003c\/p\u003e\n\u003cp class=\"nznpd__intro\"\u003eUse them as status and warning lights, front-panel indicators, or for your first blink sketch. The leads are 2.54mm apart, so they push straight into a breadboard or a standard 0.1 inch PCB, and a 5mm hole holds them in a panel. Yellow runs happily from 3.3V or 5V. Blue needs about 3V itself, so on a 3.3V pin it works with a small resistor but is brightest and most even from 5V. They are sold individually with a minimum of 10 per colour, and you will need one resistor per LED, which is not included.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003csection class=\"nznpd__block\"\u003e\n\u003ch3 class=\"nznpd__h\"\u003eSpecifications\u003c\/h3\u003e\n\u003cdiv class=\"nznpd__specs\"\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003ePackage\u003c\/span\u003e\u003cstrong\u003e5mm round top, through-hole\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eLens\u003c\/span\u003e\u003cstrong\u003eDiffused, tinted yellow or blue\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eBrightness\u003c\/span\u003e\u003cstrong\u003e600 to 800mcd at 20mA\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eForward current\u003c\/span\u003e\u003cstrong\u003e20mA maximum, 5 to 10mA suggested\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003ePolarity\u003c\/span\u003e\u003cstrong\u003eLong lead +, short lead and flat rim -\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eLead spacing\u003c\/span\u003e\u003cstrong\u003e2.54mm\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eLens size\u003c\/span\u003e\u003cstrong\u003e5mm wide, about 8.6mm tall\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eResistor\u003c\/span\u003e\u003cstrong\u003eOne per LED, not included\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eQuantity\u003c\/span\u003e\u003cstrong\u003eSold individually, minimum 10 per colour\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cbr\u003e\n\u003cp class=\"nznpd__subhead\"\u003eBy colour (typical at 20mA)\u003c\/p\u003e\n\u003cdiv class=\"nznpd__specs\"\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eYellow\u003c\/span\u003e\u003cstrong\u003e1.8 to 2.0V, 588 to 590nm\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eBlue\u003c\/span\u003e\u003cstrong\u003e3.0 to 3.2V, 460 to 465nm\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"nznpd__block\"\u003e\n\u003ch3 class=\"nznpd__h\"\u003eDatasheets\u003c\/h3\u003e\n\u003cdiv class=\"nznpd__ds\"\u003e\n\u003ca class=\"nznpd__dsbar\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0664\/6127\/0112\/files\/5mm-LED-Diodes-Datasheet-v3-1.pdf\" target=\"_blank\" rel=\"noopener\" aria-label=\"Download the 5mm LED technical datasheet (PDF)\"\u003e\n\u003csvg width=\"20\" height=\"20\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\u003e\u003cpath d=\"M14 2H6a2 2 0 0 0-2 2v16a2 2 0 0 0 2 2h12a2 2 0 0 0 2-2V8z\"\u003e\u003c\/path\u003e\u003cpolyline points=\"14 2 14 8 20 8\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\n\u003cspan\u003eTechnical datasheet - 5mm LEDs, all colours\u003c\/span\u003e\n\u003cspan class=\"nznpd__dsmeta\"\u003ePDF\u003csvg width=\"17\" height=\"17\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\u003e\u003cpath d=\"M21 15v4a2 2 0 0 1-2 2H5a2 2 0 0 1-2-2v-4\"\u003e\u003c\/path\u003e\u003cpolyline points=\"7 10 12 15 17 10\"\u003e\u003c\/polyline\u003e\u003cline x1=\"12\" y1=\"15\" x2=\"12\" y2=\"3\"\u003e\u003c\/line\u003e\u003c\/svg\u003e\u003c\/span\u003e\n\u003c\/a\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"nznpd__block\"\u003e\n\u003cdiv class=\"nznpd__qs\"\u003e\n\u003ch3\u003eWiring \u0026amp; getting started\u003c\/h3\u003e\n\u003col class=\"nznpd__steps\"\u003e\n\u003cli\u003e\u003cdiv\u003e\n\u003cstrong\u003eFind the long lead\u003c\/strong\u003e\u003cp\u003eThe long lead is the anode (+).
