Through Hole Resistors

Through hole resistors are components that resist the flow of electrical current by adding resistance to an electrical circuit, which is known as the resistance rating. Commonly used for additional power protection, precision control of current, and protection from sudden surges in voltage, Through hole resistors are used in a variety of applications. When looking for the right Through hole resistor for an application, it is important to look at the size, resistance rating, power rating, voltage rating and operating temperature for the resistance that is needed. WW3FT680R is a Through hole resistor that has a number of excellent features.

WW3FT680R Application Field & Working Principle

WW3FT680R is a Through hole resistor used in many applications from radio, TV receivers, electronic equipment, military equipment, etc. It is used to limit or discharge excessive voltages, thus providing an extra layer of power protection. It can also be used in precision control applications, current balancing, and noise cancellation. The WW3FT680R is designed to operate at a very wide range of operating temperatures, between -55℃ to +125℃. Additionally, the WW3FT680R offers good linearity, high accuracy, low temperature drift and fast response time.The working principle of WW3FT680R is quite simple. It consists of a cylindrical resistive material, usually carbon or metal film, wrapped in an insulating material. The resistive material helps in controlling the flow of current through the resistor by providing the necessary resistance. This resistance is determined by the size and material of the resistor, and can range from very low to very high. By connecting two electrodes to the resistor at either end, and supplying a voltage source to the electrodes, current will flow through the resistor, creating a voltage drop across it. This voltage drop is the ohmic value of the resistor (in Ohms). This constant voltage drop allows the resistor to act as a voltage divider which can be used to control the amount of current flowing through a circuit. Additionally, WW3FT680R has a Power rating that specifies the amount of power that the resistor can handle before it is damaged or overheated.The WW3FT680R is an ideal choice for applications that require low power ratings but high precision. It is low cost, has high pulse response, and meets many industry standards, making them a great choice for industrial applications. WW3FT680R can be purchased in several form factors, including axial, vertical, and SMD. Overall, WW3FT680R Through hole resistors are a great solution for applications that require power protection, control or noise cancellation. With its low cost, wide range of operating temperatures and excellent performance, the WW3FT680R is an essential part of any engineer’s toolbox.
