Through Hole Resistors

MFR25SJT-52-390R application field and working principle

A through hole resistor, such as MFR25SJT-52-390R, is a type of resistor used to reduce and control the flow of electricity in a circuit. Through hole resistors are commonly used in electronics for various applications such as power management, voltage regulation, signal conditioning, and signal isolation.Like other types of resistors, the basic working principle of a through hole resistor is to provide resistance against the flow of electric current. This is achieved by introducing a material with a specific resistance into the circuit, and when a current passes through it, some of the energy is dissipated as heat. The amount of energy dissipated is governed by Ohm’s Law, which states that the amount of current through a resistor is equal to the voltage across it divided by the resistance.A through hole resistor is typically made up of an insulated core surrounded by an electrically conductive metal coating or silver layer. This outer layer acts as an electrical contact point for the resistor, allowing it to be conveniently connected into a circuit. The resistor is then connected to the circuit board using two long narrow pins that extend through the board.When the two pins are soldered onto the board, the resistor is held securely in place and a low voltage current is applied, causing the metal layer to heat up and dissipate energy. This dissipated energy serves to resist the flow of current in the circuit and reduces it to a desired level.The MFR25SJT-52-390R through hole resistor is typically used for applications which require a high level of precision and reliability. It is commonly used in industrial applications, automotive electronics, communications systems, and wearable devices. It is also popular in telecommunications equipment, audio and video systems, medical equipment, and consumer electronics devices.The MFR25SJT-52-390R through hole resistor is also highly reliable and has a low thermal sagging resistance, which means it can maintain a high level of accuracy over time. Additionally, it has a high operating temperature range, allowing for greater flexibility in its application.The MFR25SJT-52-390R through hole resistor also has the capability to bear high voltage and heavy internal and external currents. This makes it an ideal choice for applications where high currents must be managed.To sum up, the MFR25SJT-52-390R through hole resistor is an effective and reliable way to control and regulate electric current in a circuit. Its high precision, durability, and ability to bear high voltage make it a popular choice in a wide variety of applications.
