Through-hole resistors are a type of electronic components that consist of two terminals connected by a resistive element. They are typically used in power circuits, as their terminals provide a secure, efficient, and reliable connection. The resistive element of through-hole resistors is usually made of ceramic, metal, or polymer, and the terminals are usually metal or an insulated ceramic material. The main purpose of through-hole resistors is to provide a stable current in the circuit, even when a wide range of voltages are applied. They can also provide protection from high-currents, water, and vibration.

The FMF200FRF73-150K through-hole resistor is a cylindrical resistor that consist of four terminals: two main contacts and a pair of secondary contacts. It is made up of a milk white ceramic body, with a blue or black band which indicates the voltage and power rating. The two main terminals are connected through a precision, molded ferrite bead, that is sealed within the body of the resistor. The secondary contacts are connected to the main terminals via a pair of heat-shrunk solderable sleeves.

The FMF200FRF73-150K through-hole resistor is primarily used in power circuits and electronics. It is frequently used as a feedback resistor in voltage regulator circuits, such as those found in Electric Vehicles (EVs) and Uninterruptible Power Supplies (UPS). The resistor is also commonly used as an overvoltage protection circuit, as its four terminals helps to reduce the Resistive Voltage Drop (RVD) effect. Other applications include current sensing, protection from electromagnetic interference, and temperature sensor circuits.

The working principle of the FMF200FRF73-150K through-hole resistor is simple. When an external voltage is applied to the main terminals, an electric current will pass through the resistor. The resistance of the resistor will be determined by its material (ceramic, metal or polymer) and the voltage applied to the circuit. The larger the voltage, the lower the resistance, and vice versa. The heat generated by the current is dissipated through the secondary contacts. This helps to protect the resistor from damage due to high temperatures.

In conclusion, the FMF200FRF73-150K through-hole resistor is an incredibly versatile and reliable electronic component. Its four terminals and precision molded ferrite bead provide reliable connections and its material and design offer optimal performance in a variety of power circuits. It is widely used as a feedback resistor, overvoltage protection circuit, current sensor, and in temperature sensor circuits. It is a reliable and cost-effective solution for the majority of power circuit applications.
