Through Hole Resistors

Through hole resistors are a common and widely used mechanical component used in circuit connection and current limiting. One of the most widely used and popular through hole resistors is the MFR25SDRF52-140R. This resistor is designed with a metal film construction for low noise and low tolerance, which makes it ideal for use in precision circuit systems.

The MFR25SDRF52-140R through hole resistor features a cylindrical body made of tinned segmented steel, with an insulation sleeve over the four walls of the body. The size of the component and its internal components determine its application field. The resistor requirements needed for specific projects depend largely on the resistors\' wattage, voltage, temperature rating, and precision. The MFR25SDRF52-140R has a power rating of 4.2W, a voltage rating of 110V, a temperature rating of -55° to +125°C, and a voltage coefficient of 0.05%.

The working principle of the MFR25SDRF52-140R relies on a process called Ohm\'s Law. Ohm\'s law states that the current in a circuit is proportional to the voltage and inversely proportional to the resistance. In other words, as the voltage applied to a resistor increases, the current through the resistor also increases. The MFR25SDRF52-140R uses this principle to limit the current passing through it, determined by the resistance value of the component. This current limit protects the other components in the circuit from damage in the case of an overcurrent.

In short, the MFR25SDRF52-140R through hole resistor is a common component used in both commercial and industrial circuit systems to protect other components in the system from being damaged due to an overcurrent. Its wattage, voltage, temperature rating, and voltage coefficient make it ideally suited for precision circuit boards. It works on a principle called Ohm\'s Law to limit the current passing through the resistor, protecting the rest of the system from damage.
