Description

A 120K Ohm 1/8W 5% Through Hole Resistor is a standard electronic component commonly used in circuits for current limiting, voltage division, or general-purpose resistance applications. It features a resistance of 120,000 ohms (120K ohms), which defines its ability to resist the flow of electrical current. The resistor is rated for 1/8 watt (0.125W) of power dissipation, meaning it can safely handle this amount of electrical power without overheating or damaging the component. The 5% tolerance indicates that the actual resistance may vary by up to 5% from the nominal value, making it suitable for general applications where high precision is not required.

The resistor is designed with a through-hole mounting style, meaning it is intended to be inserted into pre-drilled holes on a printed circuit board (PCB). This is one of the most common forms of resistor installation in both through-hole and mixed technology PCB designs. The 5% tolerance is typical for general-purpose resistors and is generally accepted in a variety of circuit designs where precision is not critical.

With a standard body size and construction, this resistor is made of a ceramic or carbon core with metal oxide or metal film coating, depending on the specific type. It is often used in consumer electronics, power supplies, and various industrial applications for stable performance under a wide range of conditions. Its durability, high resistance value, and manageable power dissipation make it an essential part of many low-power electronic circuits.
