Through Hole Resistors

The MFR25SJR-52-2K4 is one type of through hole resistors used for variable applications. It is a fixed type resistor, meaning that its resistance is constant for as long as the resistor is in the circuit. Designed with an axial leaded body, this component features a high-power rating and excellent electrical and mechanical properties.

This resistor operates by releasing a physical form of the electrical resistance across an electrical circuit in order to limit the current flow. This specific resistor provides a resistance level of 2K4 ohm, has a power rating of 25 watts and a tolerance of 5%. These elements are also encased in an epoxy coating which provides extra protection against environmental elements as well as providing a layer of insulation to further prevent voltage leakage.

Application Field

The MFR25SFR-52-2K4 is used in a variety of different application fields, both in residential and industrial settings. Commonly used in consumer electronic goods such as toasters, microwaves, and TVs, they provide stability to the device’s power supply by regulating the voltage. In industrial settings, these resistors are used to reduce current flow in motors, pumps, and energy controlling equipment by limiting their current flow.

Working Principle

At the heart of the MFR25SFR-52-2K4 is the resistor element itself. This element is made up of a wire material such as nickel or chromium which is wound in a spiral pattern around a supporting material. The number of layers of the wire and the thickness of the material determines the resistance level of the element. When a signal through a circuit, it passes through this resistor and the electrical current flowing through the wire creates heat which is released in the form of resistance.

This heat is resisted by the wire material itself, thus limiting the amount of current passing through the wire and significantly reducing the chance of short-circuiting the device. In addition to this, the supporting material also helps to dissipate the heat released, thus further decreasing the chance of overheating and allowing variable current flow in the device.

In conclusion, the MFR25SJR-52-2K4 is an extremely useful type of through hole resistors which can be used in a variety of applications, both residential and industrial. It works by releasing a physical form of the electrical resistance across an electrical circuit in order to limit the current flow and provide stability to the device’s power supply. The resistor element itself is made up of a wire material wound in a spiral pattern around a supporting material and the number of layers of the wire and the thickness of the material determines the resistance level of the element.
