LR2F430K is a through-hole resistor with an operating temperature of -40 to 125 °C, and used in a wide range of electrical applications, such as amplifiers, radio receivers, motor starters, and television. It is used for controlling the current flow and voltage drop across a circuit. It is commonly used in power supplies, voltage regulation, and signal conditioning.

LR2F430K is a fixed resistance component with a nominal resistance of 43 ohms. It is designed to be able to continuously withstand a current of 4 A, and short circuit current up to 25 A. The power ratings of LR2F430K are 2 W in general use and 5 W in the overload case. The nominal voltage rating is 35 V and the maximum working voltage is 75 V.

LR2F430K is non-inductive with a high current capacity, low temperature coefficient, and low noise. It has a high heat dissipation and wide frequency response range. It also features a high endurance and dielectric strength. Additionally, it includes heat shrink sleeves for increased temperature stability and dissipates heat away from the input port.

The operating principle of LR2F430K is relatively simple. When current passes through the resistor, some energy is dissipated through the resistor’s terminals. This energy is dissipated in the form of heat and is released into the surroundings. The resistance value determines the amount of current that can pass through it and the voltage drop across it. The resistance value in an LR2F430K is determined by the amount of carbon granules encased within a ceramic casing. These granules are packed in an airtight manner and when current passes through, it produces a resistance.

The application fields of LR2F430K include a variety of electrical applications such as motor starters, amplifiers, voltage control devices and signal conditioning. For motor starters, the resistance of LR2F430K helps control the current flowing through the motor while allowing for increased voltage rating and small amount of heat dissipation. In amplifiers, this type of resistor is used to control the current flow throughout the circuit and enable a wide range of feedback gain and operating frequencies. In voltage regulation applications, LR2F430K can help regulate the voltage in order to prevent excessive current and voltage stress. Finally, it is used for signal conditioning in audio, automotive, and medical applications.

In summary, LR2F430K is a through-hole resistor with an operating temperature of -40 to 125 °C, and used in a wide range of electrical applications, such as amplifiers, radio receivers, motor starters, and television. Its non-inductive design, high current capacity, low temperature coefficient and low noise make LR2F430K ideal for controlling the current flow and voltage drop of a circuit. Its application fields include motor starters, amplifiers, voltage control devices, and signal conditioning.
