Through Hole Resistors

Through hole resistors are one of the most common types of resistors used in circuit boards and circuit design. Typically they are used to provide a resistance between two electrical components on a circuit board in order to reduce the amount of current flowing from one component to another. Through hole resistors are available in a wide range of resistance values to meet the needs of practically any circuit design. This article will explore the PSM7WSJB-390R through hole resistor and its application field as well as its working principle.The PSM7WSJB-390R through hole resistor is a high-precision, surface-mounted component. It is designed to provide a highly accurate resistance value for applications requiring high temperature stability. The resistor can be used for a variety of applications such as motor control, power supply regulation, and temperature control. The device has a resistance in the range of 390 to 490 Ohms with an accuracy of ±0.1 Ohms. This high accuracy makes this resistor ideal for use in applications requiring precise values.The device has a very low thermal coefficient of resistance, meaning that it can maintain its resistance value over a wide temperature range. This property makes it suitable for use in high-temperature environments such as engines, motor control, and power supply regulation. The resistor also has a low self-resonant frequency. This allows the device to be used in applications that require fast switching of currents.The PSM7WSJB-390R through hole resistor is based on a Metal Oxide film resistor which is a type of resistor with good stability and precise properties. The resistor consists of a metal oxide layer with a resistor element inside. This layer is then covered with an alumina material and enamel that is used for insulation. The metal oxide layer provides a high output impedance and low input impedance, which makes it suitable for high-power applications.The working principle of the PSM7WSJB-390R through hole resistor is simple. When current passes through the resistor element, it creates a voltage drop across the device. This voltage drop is determined by the resistance of the resistor. The resistor also has a very low series inductance and is very fast responding making it suitable for switching applications.In conclusion, the PSM7WSJB-390R through hole resistor is a high-precision, low-cost component that can be used for a variety of applications. It has high accuracy, low thermal coefficient of resistance, and a low self-resonant frequency making it suitable for high-power applications. It is based on a Metal Oxide film resistor that provides a high output impedance and low input impedance making it suitable for fast switching applications.
