Resistor
220Ω Resistor
220Ω fixed resistor — the standard LED current-limiter for a 5V or 3.3V GPIO.
Generic (every passive-components manufacturer)
🍌 Simulates in-browserOverview
A plain two-terminal fixed resistor at the nominal value electronics hobbyists reach for most: 220Ω is the textbook current-limiting value for a single LED off a 5V logic pin (roughly (5V-2V forward drop)/220Ω ≈ 14mA, comfortably inside a typical LED's rating and well under most GPIO current limits). There's no meaningful 'manufacturer' for a component this generic — resistors at this value are made by essentially every passive-components company, in every tolerance and power rating, in both through-hole axial and SMD chip form. What you get in a specific kit or order varies enough (tolerance, power rating, even physical package) that most of the spec sheet below is marked varies-by-vendor rather than pretending one number applies to every 220Ω resistor ever sold.
Wiring tip: current limiting for LEDs — no polarity, either leg either way

Wiring examples
Current-limiting resistor for a single LED
Any 5V hostIn series between a GPIO and an LED's anode — the standard way to keep an LED from drawing more current than either the LED or the GPIO pin can safely handle.

|---|---|---|
| 1 | host Digital out (any matching pin) | GPIO side. The resistor's other leg (pin2) goes to the LED's anode, with the LED's cathode returning to GND — no LED part is in this catalogue release yet, so that leg isn't modeled as a formal connection here. |
- 220Ω is sized for a single standard LED off a 5V pin. A 3.3V pin, a different LED color/forward-voltage, or multiple LEDs in parallel all change the correct value — this is a common starting point, not a universal constant.
