Through hole resistors are arguably the most common type of resistors due to their ubiquity in all sorts of electronic components and circuit designs. The FMF200FRF73-3M9 through-hole resistor is a case in point. This device is a fixed resistor with four leads that are positioned in holes of a printed-circuit board.

The FMF200FRF73-3M9 is designed for general-purpose applications and has a wide operating temperature range of -55°C to +125°C. In terms of electrical parameters, it has a resistance range of 5Ohm to 75 Ohm and a power rating up to 200mW. Likewise, the component features a tolerance of 5%, an insulation resistance of 5000MΩ (at 500V DC) and a high stability over time and temperature.

The FMF200FRF73-3M9 comprises three resistive elements connected in series. Unlike common resistors, it utilizes three resistive elements so that it can reduce the inductance of the resistor and improve its frequency response. Additionally, this setup ensures that an abrupt change in the ambient temperature does not alter the output power significantly.

On one end, two small protrusions next to the leads serve as indicator bands. Both bands change color in accordance with the resistance range. As the resistor heats up, the colored bands move up the body. This is highly practical since it allows users to quickly identify the resistor’s resistance range without the need for a precise measuring device.

The working principle of the FMF200FRF73-3M9 through-hole resistor is fairly simple. When current passes through the components, they absorb energy, which causes them to heat up. As the temperature increases, resistance also increases within the resistor, and current flow diminishes. As a result, the component regulates the flow of current.

This ability to limit current makes the FMF200FRF73-3M9 suitable for a variety of applications, especially those that require a reliable power source, such as consumer electronics, automotive, and industrial devices. It is also suitable for uses that need to control power distribution or current flow, such as short-circuit protection, motor applications, and energy conversion.

In commercial practice, the FMF200FRF73-3M9 is highly popular due to its stability, good frequency response, and solid performance. It works reliably over a wide temperature range without compromising its resistance accuracy. Furthermore, the resistance elements are connected in series, which reduces their inductance and improves their overall frequency response.

In conclusion, the FMF200FRF73-3M9 is a highly reliable and durable through-hole resistor ideal for a host of applications. Thanks to its solid design, its resistance accuracy is not affected by changes in temperature. Plus, its indicator bands allow users to quickly identify the range of resistance offered by the resistor. Moreover, its three resistive elements improve its frequency response, making it an excellent choice for motor and energy conversion designs.
