A 470K Ohm 1W 5% Through Hole Resistor is an electronic component used to limit the flow of electrical current in a circuit. With a resistance value of 470,000 Ohms, this resistor is designed for applications that require a high level of resistance to control current flow. The 1W (1-Watt) rating indicates that the resistor is capable of dissipating up to 1 watt of power without being damaged, making it suitable for medium-power applications.
The 5% tolerance specification means that the actual resistance value can vary by ±5% from the nominal value (470K Ohms), providing some flexibility in performance, typically for non-critical applications. This tolerance level is common for general-purpose resistors where precise accuracy is not a stringent requirement.
The resistor features a through-hole design, meaning it is intended to be mounted on a printed circuit board (PCB) by inserting the leads into pre-drilled holes. This makes it suitable for use in traditional, through-hole PCB designs, which are often found in legacy electronics or prototyping boards.
Made from a combination of materials such as carbon film or metal oxide, this resistor is durable and able to withstand heat and electrical stress within the specified power rating. The through-hole construction provides reliable connections and robust mechanical support, ideal for various general-purpose, power-limiting, and signal-conditioning applications in circuits.
Applications include use in voltage dividers, biasing, filtering, or current-limiting circuits in consumer electronics, industrial equipment, and hobbyist projects. Its high resistance makes it particularly useful in circuits requiring minimal current flow.
