Through Hole Resistors

Through hole resistors are one of the core components commonly used in electronic circuits. They are used to control the current flow and voltage in the circuit. Today, we are mainly discussing the application field and working principle of KNP200JT-52-47R through hole resistor.

Application

KNP200JT-52-47R is a high power through hole resistor, it mainly used in the electric power system, power electronic equipment and communication system, especially in the DC high power current, voltage, speed and energy flow of actual measurement and control system. The rated power of the resistor is 200W, withstanding voltage is 7000V and the ambient temperature range is -50ºC to + 300ºC. The resistor’s resistivity is very stable with a relatively small temperature coefficient. It also has high withstand voltage and strong anti-interference capability and is mainly used as a power load resistor, an overvoltage protection resistor, a snubber receiver and a lamp driver, etc.

Working Principle

The KNP200JT-52-47R through hole resistor follows Ohm\'s law, that is, the current through a conductor is proportional to the constant voltage applied across it. For the KNP200JT-52-47R resistor, it can be used to regulate the current in the circuit, limit the voltage, match the impedance, distribute the current, and form a special sine wave filter, etc. When electricity passes through the resistor, some of the power is converted into heat energy in the form of Joule heating, and the temperature of the resistor will rise as a result. As the temperature increases, the resistivity of the resistor decreases, which affects the stability of the circuit resistance. Therefore, the KNP200JT-52-47R resistor is designed with a heat dissipation device to cool the resistor and maintain the stability of the circuit.
