Resistor 18 KOHM

Overview

The 18 kOhm (18,000 Ohm) resistor is a cornerstone passive component in virtually every electronic circuit. It's used to limit current, divide voltages, set bias points, and protect sensitive components. This 0.25W (1/4 Watt) carbon film resistor is the most common and versatile power rating, making it perfect for a wide range of hobbyist, educational, and prototyping applications. At MOKWN, we provide high-quality, reliable resistors that ensure your projects work as intended.
