These ultra-bright, through-hole light-emitting diodes provide a sharp, piercing amber-yellow light that easily cuts through ambient room lighting.\u003c\/p\u003e\n\n\u003cp\u003eAvailable at Tomson Electronics, this high-quality 5mm EVL LED features standard 2.54mm pitch spacing, allowing it to slide perfectly into solderless breadboards, perfboards, and custom PCBs. Whether you are building an alert system for an embedded LoRa mesh safety device, wiring up standby indicators for a competitive mechanical soccerbot, or just learning the basics of Arduino programming, this LED is a workbench essential.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommonly searched as:\u003c\/strong\u003e 5mm yellow light emitting diode, amber led, tx\/rx led, standby indicator light, breadboard led, EVL 5mm LED.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmitting Color:\u003c\/strong\u003e Yellow \/ Amber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens Type:\u003c\/strong\u003e Clear \/ Tinted (Ultra Bright)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForward Voltage (Vf):\u003c\/strong\u003e 2.0V to 2.2V (Typical)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForward Current (If):\u003c\/strong\u003e 20mA (Recommended)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Style:\u003c\/strong\u003e Through-Hole (DIP)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Configuration:\u003c\/strong\u003e 2-Pin (Long Lead = Anode\/Positive, Short Lead = Cathode\/Negative)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eCommon Applications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eData Transfer Indicators:\u003c\/strong\u003e Creating visual TX (transmit) and RX (receive) status lights for custom microcontrollers and communication modules.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarning \u0026amp; Standby Systems:\u003c\/strong\u003e Providing high-visibility alerts on custom 3D-printed enclosures or robotics chassis before a system is fully engaged.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreadboard Prototyping:\u003c\/strong\u003e The perfect visual debugging tool for testing logic levels on development boards like the ESP32 and Arduino Uno.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEducational Kits:\u003c\/strong\u003e Teaching fundamental electronics concepts, circuit polarity, and current limiting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eFrequently Asked Questions\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need to use a resistor with this LED?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes, absolutely. If you connect this yellow LED directly to a 5V or 3.3V power source without a current-limiting resistor, it will burn out immediately. For a standard 5V Arduino logic pin, a 220-ohm or 330-ohm resistor is highly recommended.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How do I know which leg is positive and which is negative?\u003c\/strong\u003e\u003cbr\u003e\nA: The longer metal leg is always the Anode (Positive). Additionally, if you look closely at the plastic base of the LED, there is a small flat edge—the pin closest to that flat edge is the Cathode (Negative).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between this EVL LED and a diffused LED?\u003c\/strong\u003e\u003cbr\u003e\nA: This EVL version features a clear or lightly tinted lens designed for maximum brightness, acting like a tiny spotlight. A diffused LED has a cloudy, matte finish that spreads the light out for a softer, wider glow.\u003c\/p\u003e\n\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × 5mm Yellow LED (Ultra Bright) - EVL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EVERLITE","offers":[{"title":"EVL","offer_id":49488613671150,"sku":"LED-28892","price":1.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/5mm_Yellow_LED_Ultra_Bright_EVL.jpg?v=1787590300","url":"https:\/\/www.tomsonelectronics.com\/products\/5mm-yellow-led-yellow-diffused-lens","provider":"Tomson Electronics ","version":"1.0","type":"link"}
