Through Hole Resistors

Through Hole resistors are electronic components used to control and limit the flow of electricity in a circuit. RWR89S82R5FPS70 specifically are resistors that are mounted through holes in the printed circuit board (PCB). This style of resistor allows for proper lead spacing and thermal dissipation.

Application Field

Through hole resistors are used ubiquitously throughout a wide variety of electrical and electronic applications and products, such as electronic timing devices, circuit protection, computers, and other telecom devices. Due to the numerous uses of through hole resistors, it’s no surprise that most electrical engineers have experience using them. In the automotive industry, through hole resistors are commonly used in motor control circuits, ABS systems, and other electronic circuitry controlling the operation of various systems and functions. For instance, in an automotive starter motor control circuit, through hole resistors are used to protect transistors from excessive current. Aerospace and defense require precision electronic components like through hole resistors due to the high reliability of operation and performance. Through hole resistors are used in these applications to control the current during fly-by-wire systems, missile guidance, navigation systems, and other highly advanced electronic circuits. In the medical field, through hole resistors help maintain the accuracy of electronic circuits used in medical diagnostics, medical imaging, medical monitoring, and other equipment.

Working Principle

The RWR89S82R5FPS70 through hole resistors work on the principle of resistance. When a voltage is applied across the resistor, electrons flow from one end to the other and a corresponding current is created. The current is then limited by the resistance of the resistor.The resistance of the RWR89S82R5FPS70 through hole resistor is printed onto the component. The resistance is typically printed as a series of 3 or 4 numbers, each separated by a single letter. The letter is a representation of the value, with R corresponding to units of ohms and F corresponding to units of 10 ohms. The value of the resistor can then be either calculated or looked up in an electronic components catalogue.Through hole resistors also come with a power rating. This rating denotes how much power the resistor can handle before it becomes damaged or overheats. The power rating typically ranges from ¼ watt to 5 watts, depending on the specific type of resistor.The RWR89S82R5FPS70 through hole resistors come in various shapes and sizes, but the most common type is the axial-leaded resistor. This type of resistor has two leads extending from each end, allowing for easy installation and removal. The resistance and power rating are printed onto the resistor in small ink letters and numbers. Housed inside the RWR89S82R5FPS70 through hole resistor is a ceramic core. The ceramic core is made up of an inner core of metal oxide and an outer coating of silica glass. The ceramic core is an ideal material for dissipating heat and providing the resistor with a high level of dielectric insulation. Through hole resistors are typically much larger than their surface mount counterparts due to their construction and typically require longer lead lengths, making them less suitable for crowded PCBs. However, they can be used in applications where high power or higher reliability is required. In conclusion, through hole resistors are widely used components in the field of electrical and electronic engineering. They are used in applications such as automotive, aerospace and defense, and medical applications, and they provide a reliable and effective way to control current in a circuit. The RWR89S82R5FPS70 is a specific type of through hole resistor, and it operates on the principle of resistance, limiting the flow of current when a voltage is applied across its terminals. It comes in various shapes and sizes, and it has a power rating that must be taken into consideration when selecting the appropriate resistor for a particular design.
