Through Hole Resistors

Through-Hole Resistors (THR) are passive electrical components usually composed of a ceramic body and a tinned annealed copper wire wound around it. Commonly used in residential and commercial applications, THR resistors are designed to reduce current or voltage, limit current flow, and provide electrical insulation. Typical applications for THR resistors include controlling the levels of electrical current in various circuits, providing resistance for motor control, and acting as a resistor to limit inrush current.

MFR-50FRE52-118R

The MFR-50FRE52-118R is a Through-Hole Resistor used for a variety of applications, especially those that require resistance to higher mechanical and environmental conditions. This type of resistor is characterized by its ability to withstand higher wattages, temperatures, and vibration than standard through-hole resistors. The MFR-50FRE52-118R is a medium-power, air-core resistor with power dissipation levels of up to 50W. It also features a standard 1/4" bushing and is available in a selection of standard high-voltage ratings.

Application Field and Working Principle

The MFR-50FRE52-118R is typically used in applications such as high-voltage circuits, motor belt drives, and light control systems. It is highly reliable and offers excellent electrical isolation and long-term operation in demanding environments. This Through-Hole Resistor has a low-profile design, which makes it suitable for use in confined spaces, while its robust construction makes it ideal for industrial applications such as vibration detection or power conditioning. It also offers an exceptionally low-resistance value, which makes it ideal for precision control applications.

The working principle of the MFR-50FRE52-118R is similar to other Through-Hole Resistors. It is composed of two main elements: the body and the copper lead. When an alternating current passes through the copper lead, the electricity is converted to heat energy and dissipated away from the resistor, thus providing the resistance to the current flow. The ceramic body of the resistor serves as an insulator, further limiting the amount of heat that can be dissipated away from the resistor and thus limiting the current flow through the component.

The MFR-50FRE52-118R Through-Hole Resistor offers excellent performance in a wide range of applications. This type of resistor offers high-reliability, long-term performance, and increased resistance to mechanical and environmental stress. It is reliable, temperature-stable, and vibration-resistant, and offers an exceptionally low-resistive value, making it ideal for a variety of applications such as motor belt drives, light control systems, and high-voltage circuits.
