Through Hole Resistors

Through hole resistors such as the MFR50SFRE52-221K have been used in the field for a variety of applications. They are designed to have a high degree of accuracy and reliability, while also providing superior protection against the harsh environments found in industrial settings.The MFR50SFRE52-221K is a through hole resistor that has a maximum power rating of 50 watts and a resistance value between 200 and 500 ohms. It is constructed with a variety of ceramic substrates. It also has a frequency up to 4 MHz, a pulse width up to 30 μsec, and an operating temperature range of -40°C to +85°C.The working principle of the MFR50SFRE52-221K is based on the fact that an electric current travelling along a wire produces a magnetic field around the wire. This magnetic field can be used to resist the current flow, and thus act as a resistor. The MFR50SFRE52-221K utilizes the same principle, but instead of being a wire, it is built using thin layers of ceramic dielectric material paired with different layers of thick, metal plates. This produces an accurate and reliable resistive element that can handle high power ratings without breaking down.The MFR50SFRE52-221K has been designed to provide maximum protection in a variety of industrial settings. It has an ESD (electrostatic discharge) rating of 8kV to protect it from static electricity, and it is rated for surge currents of up to 150A. It also comes with a variety of solderable terminals, which provide additional protection and durability when the resistor is used in a system.The MFR50SFRE52-221K is widely used in a variety of applications including power supply, control, and audio impedances. It is perfect for controlling electric current in circuits that require precise amounts of power, and it is often used in motor control systems, as well as other demanding industrial applications. Its robust and reliable design make it perfect for use in automotive, power equipment, computer, telecommunications, lighting, and other industries.The MFR50SFRE52-221K is available in various packages, offering increased versatility and reliability. It has an angled lead model, a hermetically sealed package, and a sub-miniature package for easy installation in tight spaces. It also has dip switch packages with pre-drilled holes for extra protection, and upgraded terminals for better durability.In conclusion, the robust design and superior reliability of the MFR50SFRE52-221K make it an ideal choice for industrial and commercial applications. It is a perfect solution for controlling electric current in power supply, control, and audio impedances, providing superior protection from harsh environmental conditions.
