Throughout history, the development of electrical engineering has been a component of the driving force of technological development. Through Hole Resistors are likewise an essential part of the electrical engineering field. Those resistors serve the purpose of limiting current in circuits and, more importantly, providing protection from over-currents to the components in the circuit. One of the many Through Hole Resistors available for use in today’s electronic systems is the MFR-25FBF52-1M18.

The MFR-25FBF52-1M18 is a low-cost, 0.5 watt resistor with small size and high reliability. It is primarily used in audio systems, computers, and electric tools. The resistor has an operating temperature range from -55 to +125 degrees Celsius. It has a rated power of 0.5W, a rated voltage of 100V, and a low resistance tolerance of 5%. It also has a low-temperature coefficient of 50 +25 ppm/°C and a maximum allowed ambient temperature of +105°C.

In terms of its construction, the MFR-25FBF52-1M18 consists of a copper body that is coated with a temperature-resistant resin to prevent heat from escaping. It also features an ultra-thin metal-oxide film, which is deposited onto the surface of the copper body and then fired in a furnace. This helps to provide a very low-temperature coefficient and a high resistance accuracy factor. The copper body also features a uniform tin-plating, which also helps to give the resistor a consistent resistance value.

The working principle of the MFR-25FBF52-1M18 is relatively simple. A signal current is applied to the resistor and, in response to the applied voltage, the resistor will emit an opposing electrical current. This current is then used to counterbalance the original signal current, resulting in a current that is now at a level that is safe for the components in the circuit. The resistor is able to accurately regulate and limit current by adjusting the resistance of the resistor in relation to the voltage of the circuit.

Due to its size, reliability, low-cost, and resistance accuracy, the MFR-25FBF52-1M18 is an ideal choice in applications where a low-cost resistor with good accuracy and reliability is needed. Its application fields range from audio systems and computers to electric tools and instruments. Its ultra-low temperature coefficient makes it ideal for applications where a stable, reliable, and accurate current needs to be maintained.

In summary, the MFR-25FBF52-1M18 is a Through Hole Resistor that is ideal for applications that require accurate current regulation, reliability, and low cost. Its small size, good heat resistance, and low-temperature coefficient make it an ideal choice for many types of electronic systems. Its application fields range from audio systems and computers to electric tools and instruments. By understanding how it works, engineers can better utilize the MFR-25FBF52-1M18 and maximize the potential benefits of its use.
