LED - Yellow with Resistor 5mm (25 pack)

You don’t have to worry about adding a resistor to an LED if you get an LED with a built in resistor! This pack of 25 yellow 5mm LEDs will help alleviate any frustrations you’ve had with accidentally burning them out by having a resistor in the diode itself. Each LED has an operating voltage range of 2.0V to 5V to help make your next project shine!

Each pack of these LEDs are conveniently bagged in reusable ESD safe packaging to make sure nothing accidentally gets damaged before you are able to use them.

  • 25x Yellow LED w/ Resistor - 5mm
  • Operating Voltage Range: 2.0V-5.0V
  • Standard Size - T1 ¾ 5mm
  • Brightness: 2000-2500 MCD
  • Color: 585-595 NM

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Customer Comments

  • I am a bit confused.. the photo shows a 9V battery directly connected to the LED but your product description states “Each LED has an operating voltage range of 2.0V to 5V…”

    • The datasheet says something about 5V for the forward voltage. Testing it out @ 5V, it pulls about 18mA. It has been working fine at 9V and pulls about 30mA. This is probably at the higher end of the input voltage. (PS: Any higher, I’d be worried. At about 16V, the LED blew out under our stress tests).
