Through Hole Resistors

Through Hole Resistors are one of the oldest and most reliable types of resistors available for use in electronic circuits. They are constructed out of a metal core, usually a conducting material like copper or tin. The metal is surrounded by a dielectric material like ceramic, clay, or plastic. The dielectric makes the resistor less prone to shorting out. The dielectric also helps to maintain a constant impedance level over the resistor\'s life.One type of Through Hole Resistors is the CB5JBR390. This resistor is made up of a metal core with an integrated oxide layer which helps to reduce the electrical noise associated with it. The oxide layer also helps to improve the heat dissipation by providing a thermal boundary layer. The resistance of this resistor can range from 0.1ohms to 1.2Kohms.The application field of the CB5JBR390 resistor is inmany areas including: interconnects, power supplies, motor control, digital signal processing (DSP), wireless communication, and audio/video applications. It is also used in applications where high power transfer is required.The working principle of the CB5JBR390 resistor is based on the use of a dielectric material, combined with a metal core, to createa constant impedance path. The dielectric-metal combination helps to reduce the electrical noise associated with the resistor and also allows for a controlled current to flow through it. The resistor\'s stability over time is due to its resistance staying constant over a specified range of temperatures.The CB5JBR390 resistor is also designed to reduce the thermal dissipation of the components it is connected to. Because it is thermally isolated, it doesn\'t allow the heat produced by the power supply to transfer to the other components of the circuit. This helps to reduce the risk of component damage.The CB5JBR390 resistor is a great option for many high-power applications. Itsthermal stability and oxidation protection help to prevent damage to the semiconductors in the circuit, offering reliable performance for a long time.
