A 1K Ohm 1W 5% Through Hole Resistor is a standard electronic component used for limiting or controlling the flow of electric current in a circuit. The value of this resistor is 1,000 ohms (1K), meaning it offers resistance of 1,000 ohms to the passage of electric current. The "1W" indicates that the resistor is rated to dissipate up to 1 watt of power safely, meaning it can handle relatively higher currents without overheating or being damaged. The "5%" tolerance means that the actual resistance can vary by up to 5% from its nominal value, which is typical for general-purpose resistors. This resistor is designed with through-hole mounting, meaning it has leads that go through holes in a circuit board and are soldered to the board on the other side. It is widely used in various electronic applications, such as voltage dividers, signal filtering, current limiting, and in power supplies, where moderate power dissipation and reliable performance are required. These resistors are commonly found in consumer electronics, industrial control systems, and prototyping projects. The through-hole design also ensures a strong mechanical connection, making the resistor suitable for more rugged or permanent applications.
