Description

A 120 Ohm 2W 5% Through Hole Resistor is a passive electronic component designed to limit the flow of electric current in a circuit. With a resistance value of 120 ohms, this resistor provides a moderate amount of resistance, making it suitable for a variety of applications, such as voltage division, current limiting, or protecting sensitive components. The "2W" in the description refers to the resistor’s power rating of 2 watts, indicating it can safely dissipate up to 2 watts of power without risk of overheating or failure.

The "5%" tolerance specification means the resistor’s actual resistance can vary by ±5% from the nominal value of 120 ohms, providing flexibility in situations where precise resistance isn't crucial. These resistors are typically used in applications where a moderate level of power dissipation is required and where the tolerance does not need to be extremely tight.

The through-hole design of this resistor indicates it has two leads (legs) that are inserted through holes in a printed circuit board (PCB) and soldered in place, ensuring stable and reliable electrical connections. This construction is common in many older or hobbyist-level circuits, as it allows for easier handling and installation.

The 120 Ohm value is useful in a wide range of circuits, from simple LED current-limiting resistors to more complex signal processing applications. It is made of durable materials like carbon film, metal oxide, or metal film, ensuring it can withstand regular electrical loads and environmental factors.
