FKN300FR-73-13R

Through hole resistors are electronic components used to limit the flow of electricity in a circuit or system. Generally, they are constructed of a cylindrical insulating material coated with a sacrificial material, such as zinc, copper, or nickel, and an insulating layer on top. Since the current of the resistor is limited, the amount of current flowing through the circuit is also limited, which can protect the components from overheating and other damage.The FKN300FR-73-13R is a through-hole resistor capable of withstanding temperatures up to +125°C. Its construction consists of a finely grooved ceramic body with metalized contacts, a silicone fill and a silicone-coated, high temperature barrier layer. The FKN300FR-73-13R is designed to withstand thermal, mechanical and electrical shock and vibration, making it ideal for use in demanding environments such as in the automotive, aerospace and military industries.The FKN300FR-73-13R through-hole resistor has a wide range of application fields. For example, it can be used in high voltage circuits, high temperature environments, and as protection against overvoltage transients. In the automotive industry, it can be used to protect the vehicle’s electrical systems from power spikes, regulate voltage, and control the speed of electric motors. Additionally, this type of resistor can be used in aerospace applications, such as in guidance and navigation systems, and other military systems.The working principle of the FKN300FR-73-13R is based on Ohm’s law, which states that the current passing through a conductor is directly proportional to the voltage across it. When used in a circuit, the FKN300FR-73-13R acts as a resistive device, where a voltage is applied to one end of the resistor, and the current passing through it is reduced. The amount of resistance the resistor creates is determined by its construction, including its length, width, metal composition, and the type of insulating material used. As the voltage increases or decreases, so will the amount of current flowing through the resistor.The FKN300FR-73-13R has a power rating of 5 watts and thermal resistance of 25°C/W, which means it can dissipate up to 125°C of accumulated heat. This resistor is designed to provide reliable operation over long periods of time, and its high-temperature grade capability make it ideal for use in industrial environments.In summary, the FKN300FR-73-13R is a through-hole resistor capable of withstanding temperatures up to +125°C, and has a wide variety of applications, including protection against overvoltage, regulating voltage, controlling electric motors, and use in guidance and navigation systems. Its working principle is based on Ohm’s law, which states that the current is directly proportional to the applied voltage. Its power rating and thermal resistance make it an ideal device for use in harsh conditions, and its reliability ensures that it will provide long-term stability.
