Through Hole Resistors

Through hole resistors are passive components used to restrict the flow of current in an electrical circuit. A typical through hole resistor consists of a cylindrical body made of a ceramic material with two metal terminals extending from each end. The ceramic body is usually coated with a thin layer of conductive material to protect it from corrosion or other environmental effects. The terminals are connected to conductors such as wires or printed circuit boards. The resistor\'s value is determined by the ratio of the resistance between the two terminal leads. The WW2JB1K20 is a through hole resistor designed specifically for high voltage applications. This resistor is constructed from a rectifier glass that is powder coated with a silicone dielectric. The terminals, which are made from brass, are designed to reduce the risk of micro-breakdown which can occur in high voltage equipment due to the large electric fields created by high-voltage circuits. The contact surface has also been designed to reduce electrical contact resistance and improve thermal cycling performance. The WW2JB1K20 is also designed to reduce inductive loading which can lead to power losses and distortion in the circuit.The WW2JB1K20 operates by restricting the current flow through the resistor. The resistance value is determined by the ratio of the resistance between the two terminal leads, which is calculated in Ohms. The voltage drop across the resistor is determined by the current flowing through the resistor, which is calculated in amperes. The power dissipated by the resistor is determined by the voltage drop multiplied by the current. The power dissipated by the resistor ranges from 0.25W up to 25W. The WW2JB1K20 has a variety of uses in electronic circuits. It is widely used in power supplies, inverters, electronic ballasts, and other applications which require a high voltage resistor with a low electrical contact resistance. It is also widely used in automotive electronics due to its excellent thermal cycling performance and reliable performance in high voltage applications. In summary, the WW2JB1K20 is a through hole resistor designed for high voltage applications. It is constructed from a rectifier glass powder-coated with a silicone dielectric and has brass terminals designed to reduce the risk of micro-breakdown. It operates by restricting the current flow and the resistance and power dissipated by the resistor is determined by the ratio of the resistance between the two terminal leads, the current flowing through the resistor, and the voltage drop across the resistor. It is widely used in power supplies, inverters, electronic ballasts, and other high voltage circuits due to its excellent thermal cycling performance and reliable performance in high voltage applications.
