Description

A 390 Ohm 2W 5% Through Hole Resistor is a fixed resistor commonly used in electrical and electronic circuits to limit the flow of current and protect sensitive components. This particular resistor has a resistance value of 390 ohms, which determines how much it resists the electrical current in a circuit.

• Power Rating: The 2W (2 watts) power rating indicates that the resistor can safely dissipate up to 2 watts of power without overheating. This rating ensures that the resistor can be used in circuits where moderate amounts of power are being used.

• Tolerance: The 5% tolerance means that the actual resistance value could vary by up to 5% from the nominal value of 390 ohms. This tolerance is typical for general-purpose resistors and makes them suitable for most standard applications where precise resistance is not critical.

• Through Hole Mounting: The resistor features a through-hole design, meaning it has two metal leads that pass through holes in a printed circuit board (PCB) and are soldered into place. This mounting style is ideal for prototyping, repair, and situations where higher mechanical strength is required.

This 390 Ohm resistor is often used in voltage divider circuits, current limiting, pull-up/pull-down applications, and in various other areas where a specific resistance is needed to control current or voltage levels. The 2W power rating allows it to be used in circuits with moderate current flow without the risk of overheating. It is typically made of a carbon film, metal oxide, or metal film material, providing a good balance between cost, performance, and durability.

Overall, the 390 Ohm 2W 5% Through Hole Resistor is a versatile, reliable, and commonly used electronic component suitable for a wide range of applications.
