<h1>Through Hole Resistors - CFR3WSJT-73-20R Application Field and Working Principle</h1><p>Through-hole resistors, also known as "fixed resistors," are one of the most popular and common type of resistive components used in electronic circuit design and construction. The CFR3WSJT-73-20R through-hole resistor is a specific type of resistor manufactured by Panasonic and is commonly used in a range of applications. This article will discuss the application field and working principle of this particular type of through-hole resistor.</p><h2>Application Field</h2><p>The CFR3WSJT-73-20R resistor is designed for use in a wide range of applications. This resistor is suitable for use in power supply and power conversion circuits, as well as for motor control and other high-power circuit applications. It is also well-suited for applications requiring a tight temperature coefficient of the resistance. The resistor is available in a variety of mountings, including through-hole mount, surface mount, and screw terminal.</p><h2>Working Principle</h2><p>Resistors are conductors of electrons, and are used to control the flow of current within a circuit. In the case of the CFR3WSJT-73-20R resistor, the resistance is created by passing a current through a metallic film deposited onto an insulating substrate. The resistance is determined by the properties of the metallic film, such as its thickness, composition, and temperature coefficient. The resistor is conductive on one side and non-conductive on the other, thus forming what is known as the “resistor sandwich.”</p><p>The strength of the current through the resistor depends on both the voltage applied and the resistance of the component. When the voltage is increased, the current in the circuit increases, thus creating a larger drop in voltage across the resistor. Conversely, when the voltage is decreased, the current will also decrease, resulting in a smaller drop in voltage. This is referred to as the Ohm\'s Law, which states that the current flowing through a resistor is directly proportional to the voltage applied across it.</p><p>The CFR3WSJT-73-20R resistor is designed to resist the flow of electrons through it in a fairly consistent manner over a wide temperature range, and is capable of dissipating up to 200 watts of power without overheating. This makes the resistor suitable for use in a variety of high-power applications, and its wide temperature range also makes it suitable for use in temperature-sensitive applications such as motor control circuits.</p><h2>Conclusion</h2><p>The CFR3WSJT-73-20R through-hole resistor is designed for use in a wide range of applications requiring high-power handling and a tight temperature coefficient of resistance. The resistor is created by passing a current through a metallic film deposited onto an insulating substrate, and its resistance is determined by the properties of the metallic film. This resistor is capable of dissipating up to 200 watts of power without overheating, making it an ideal choice for power supply and power conversion circuits, motor control circuits, and other high-power circuit applications.</p>
