Through Hole Resistors, typically referred to as THRs, are an important component of any electrical device. They help regulate the current flow by providing resistance in the circuit. The H473R2FYA THR is a widely used resistor today, and is known for its reliable performance and low overall cost. In this article we will discuss the application field and working principle of the H473R2FYA THR.

The H473R2FYA THR is a low-power wire-wound resistor with an insulated-can construction. It is a two-terminal TRW with a resistance range of 3.3 to 10 ohms. It is designed to be used in a variety of applications, such as current sensing, voltage divider networks, audio amplifier and motor drive circuits. It is also capable of coping with large voltage swings that are common in automotive, industrial, and communications circuit applications.

The working principle of the H473R2FYA THR revolves around the concept of resistance. Essentially, resistance is the opposition to the flow of electricity. This is caused by materials that are poor conductors, such as carbon, ceramic, or other non-metallic compounds. The H473R2FYA THR works by using this resistance to control the amount of current that can pass through it. By limiting the amount of current that passes through the THR, it can be used to regulate a variety of electrical characteristics, such as voltage, power, and frequency.

The H473R2FYA THR is also designed in such a way that it can withstand both extreme temperatures and high vibration levels without adverse affects. The maximum rated operating temperature for the THR is 125°C, and it can withstand temperatures as low as -65°C without any degradation in performance. It is also designed with high-pressure contacts to ensure a reliable connection even after prolonged exposure to extreme vibration. This makes it particularly suitable for applications where vibration is a concern.

The H473R2FYA THR is a versatile component that can be used in a variety of applications. It is designed to provide reliable performance in harsh environments, and can be used to regulate the current in audio amplifier or motor drive circuits. Its combination of high power rating, wide resistance range, and vibration resistance makes it an excellent choice for applications requiring a reliable THR.
