WW12FT7R68

WW12FT7R68 is a type of through-hole resistor, which is based on simple, reliable, low-cost method of connecting components to a printed circuit board (PCB). Through-hole resistors find widespread use in many electronic circuits for providing a range of resistive values, and can also be used for their temperature and power dissipation characteristics. The WW12FT7R68 is comprised of two metal parts - a resistor element and a cap. The resistor element is a cylindrical, tubular metal conductor that is soldered to one side of the PCB using a PTH (plated-through-hole) process. The cap is a disk-shaped part with two small holes to accommodate a pair of PTHs, and this second part is then soldered to the other side of the PCB.In terms of application fields, through-hole resistors are typically used in power supplies, analog and digital circuits, telecommunications, audio and video equipment, automotive applications and industrial controls. In addition, they can also be used as components of decoupling capacitors for preventing ground bounces, reducing noise interference, and providing transient protection. The main working principle of a through-hole resistor is that its resistance is a function of both its length and its diameter. Therefore, the resistance of a resistor can be altered by changing its size, as well as its material, which is usually made from either brass, copper, or aluminum. The electrical resistance of the resistor determines the amount of electrical current that is able to pass through it, and the current is basically proportional to the force applied to it. Apart from resistors, through-hole components are also used for connecting capacitors, inductors, transistors, integrated circuits, connectors, switches, and other components. This method of soldering components is often preferred as it offers better thermal stability and eliminates potential problems associated with thermal expansion and contraction of components.Overall, through-hole resistors are ubiquitous components that provide reliable performance in a wide range of electrical and electronic circuits. They are easy to assemble, cost-efficient, and are designed to last for a long time. Furthermore, these components are also highly resilient against the harsh outdoor environment and can also withstand extreme temperatures, making them one of the most reliable resistors available.
