22k Ohm Resistor

The 22k Ohm Resistor is a high-quality metal film resistor designed to provide precise and stable resistance in electronic circuits. With a resistance value of 22,000 ohms (22kΩ) and a power rating of 1/4 Watt (0.25W), this resistor is perfectly suited for low-to-medium power applications commonly found in hobbyist and professional electronics. The metal film construction offers superior performance compared to standard carbon film resistors, providing lower noise, better temperature stability, and higher accuracy. With a tight 1% tolerance, the actual resistance stays very close to its rated value, making it ideal for circuits that demand precision. It has been tested to work perfectly with Arduino and other microcontroller platforms, making it a favorite among DIY enthusiasts.
