Through Hole Resistors: KNP7WSJB-91-180R Application Field and Working Principle

Through hole resistors are small electronic components with a wide range of applications. Through hole resistors are designed to decrease or block electric current flow in an electronic circuit. The KNP7WSJB-91-180R resistor is one type of through hole resistor that can be used in specific applications. In this article, we will discuss the application field and working principle of the KNP7WSJB-91-180R resistor.The KNP7WSJB-91-180R resistor is a type of through hole resistor that is used in high-power power electronics applications. It offers superior performance compared to other types of resistors, such as chip resistors, due to its high power rating and temperature range. The resistor is suitable for applications that require high level of accuracy, such as in motor control and switch mode power supplies.The KNP7WSJB-91-180R resistor has two metal contact strips which are separated by a ceramic substrate. The ceramic substrate is made of alumina and the contact strips are made of gold plated contact materials. The two contact strips are connected to a terminal lead which connects to an external circuit. The ceramic substrate offers superior insulation and heat dissipation. The resistor is rated at 180A at its maximum power and is capable of handling currents up to 68A during bursts.The KNP7WSJB-91-180R resistor also has an internal chip structure which consists of many layers of resistive material. The internal chip is the key to the resistor’s high power rating as the structure is capable of dissipating high amounts of heat. The chip is also designed to maintain high accuracy and stability of the resistive values.The working principle of the KNP7WSJB-91-180R resistor is simple yet effective. When a voltage is applied across the external terminals, a current passes through the resistor. The current passes through the ceramic substrate and the contact strips, and is then dissipated as heat. As the current passes through the resistor, it causes a decrease in the voltage, thereby reducing the overall current flow. This reduction in current flow is what makes the resistor effective in controlling current flow in electronic circuits.The KNP7WSJB-91-180R resistor is a versatile type of resistor which can be used in a variety of applications in the power electronics industry. It offers superior performance compared to other types of resistors and is capable of handling high currents during bursts. Furthermore, the internal chip structure ensures accurate and stable resistive values, making it suitable for applications that require high accuracy.
