Description

A 220Ω carbon film resistor rated 1/2 W with ±5% tolerance, in the standard through-hole axial package. It pushes straight into a breadboard, fits every Arduino and Raspberry Pi tutorial, and solders into any 2.54 mm perfboard.

Typical uses for 220Ω: LED series resistors on 5 V, pull-downs and audio pads.

What it does

Sets current or divides voltage in any circuit
Fits breadboards, perfboard and PCBs with 2.54 mm spacing
Colour-banded so the value can be read without a meter
