Through Hole Resistors - OM4345E-R58 application field and working principle

Through-hole resistors are one of the oldest components used in electrical engineering. They consist of a wire-wound metal or ceramic body, whose resistance value is specified in either ohms or kilohms. Through-hole resistors, also known as through-hole mounted resistors, are usually used when a component must be reliably mounted on an interior printed circuit board (PCB). These resistors come in various sizes, values, and tolerances, making them highly versatile.The OM4345E-R58 is one of the family of through-hole resistors manufactured by Ohmite. This type of resistor is designed to provide a wide range of resistance values, and is perfect for applications that require a high-precision, reliable, and low-voltage resistance component.The OM4345E-R58 consists of an aluminum core, with a wire-wound resistor and base. The resistor body is rated with a voltage of 500V, with a capacitance of 20 S/F, and a temperature coefficient of 125ppm/°C. The tolerance range for this type of resistor is very low, with 0.1%, 0.04%, and 0.1% being typical. As with the majority of through-hole resistors, the OM4345E-R58 is packaged as a radial leaded unit.Apart from being used in PCBs, the OM4345E-R58 is used in many other applications, such as voltage regulation, noise filtering, temperature sensing, and current sensing circuits. This versatility makes the OM4345E-R58 one of the most widely used types of through-hole resistors.When it comes to working principle, the OM4345E-R58 uses Ohms Law to determine its resistance value. In brief, the resistance of a wire-wound resistor is proportional to the ratio of its length, its cross-sectional area, and the specific resistance of the material that it’s made of. Since the OM4345E-R58 is composed of a metal core, its resistance value is determined by the length and diameter of its core, as well as the specific resistance of the chosen metal.The OM4345E-R58 is also designed to maintain a very consistent resistance value over time. Thanks to its low temperature coefficient and very low tolerance values, even if the surrounding temperature changes, it still remains relatively stable.Overall, the OM4345E-R58 is a robust and reliable resistor suited for a variety of applications. Its high degree of precision, low tolerance value, and resistance stability make it an extremely reliable choice, both for the commercial as well as industrial markets. By providing accurate resistance measurements in a wide variety of temperatures and electrical environments, the OM4345E-R58 makes it an ideal choice to be used in a wide range of applications.
