Through hole resistors are a simple, reliable and cost-effective option for controlling currents in a circuit. In this article, we will discuss the application field and working principle of RWR82S3740FRBSL, as well as the types of resistors and their electrical characteristics.ApplicationsThrough hole resistors are used in a wide variety of electronic applications, including consumer electronics, automotive electronics, aerospace electronics, computers, telecommunications, and medical applications. In consumer and automotive electronics, through hole resistors are used in signal conditioning, such as for audio amplifiers and LED lighting. In the aerospace and military industries, through hole resistors are used to provide power for devices such as radar systems and missiles. In computers and telecommunications, through hole resistors are used for power management, as well as in board-level protection circuits. In medical electronics, through hole resistors are used in implantable electronic medical devices, such as pacemakers, implanted defibrillators, and glucose monitors.Working PrincipleThrough hole resistors work by providing a specific amount of resistance in a circuit. This resistance is measured in ohms, and it limits the flow of current through a circuit by dissipating energy in the form of heat. When current passes through a resistor, the resistor converts this current to heat energy, which is then dissipated into the surrounding environment. By limiting the flow of current, through hole resistors protect the circuit from over current conditions, which can cause the circuit to malfunction or fail.Types of Through Hole ResistorsThere are various types of through hole resistors, depending on the application and the desired electrical characteristics.Carbon Composition Resistors: Carbon composition resistors are a type of through hole resistors made of carbon compound paste, which has excellent stability and low noise characteristics. They are suitable for general purpose applications such as audio amplifiers, LED lighting, and consumer electronics.Metal Film Resistors: Metal film resistors are made of a thin metal film, which provides excellent stability and accurate resistance values. They are suitable for precision applications such as in instrumentation and medical electronics.Wire Wound Resistors: Wire wound resistors are made of a thin metal wire wound on a ceramic core. They have excellent power handling capabilities and are suitable for high power applications such as in power supply circuits.Electrical CharacteristicsThrough hole resistors have various electrical characteristics which are important for selecting the appropriate resistor for a particular application.Resistance: This is the basic electrical characteristic of a resistor, and it is measured in ohms.Power Rating: This is the maximum amount of power that a resistor can dissipate without burning out, and it is measured in watts.Temperature Coefficient: This is the amount of change in resistance when the temperature changes, and it is measured in parts per million (ppm).Voltage Rating: This is the maximum voltage that a resistor can safely handle without burning out, and it is measured in volts.Tolerance: This is the degree of accuracy of the resistance value, and it is measured as a percent of the rated value.In conclusion, through hole resistors are a simple, reliable and cost-effective option for controlling currents in a circuit. RWR82S3740FRBSL is a through hole resistor that is suited for a wide variety of applications, including consumer electronics, automotive electronics, and medical electronics. Furthermore, through hole resistors have various electrical characteristics which are important for selecting the appropriate resistor for a particular application.
