2.2KΩ Resistor – 1/4 Watt Carbon Film Resistor
A 2.2kΩ (2.2 kilo-ohms) resistor is a commonly used resistor with a resistance of 2200 ohms. The unit "kΩ" stands for kilo-ohms, which is equal to 1000 ohms. So, a 2.2kΩ resistor has a resistance of 2200 ohms. The 2.2K ohm resistor is a general-purpose carbon film resistor with a ±5% tolerance, ideal for pull-up/pull-down configurations, LED current limiting, and voltage dividers in Arduino and electronic circuits.
