Through hole resistors are devices that resist the flow of current. They are commonly used in electrical and electronic circuits for impedance matching, signal filtering and voltage regulation. The OM82G5E-R58 is a type of through hole resistor that is designed for high power applications. It is manufactured with advanced technology and is characterized by high precision, high reliability and low temperature coefficient.

The OM82G5Es design is based on a single hole, metal-oxide film resistor. It is composed of a substrate, a passivation layer, a resistive layer, and a metal outer layer. The substrate is usually made of alumina ceramic, epoxy resin or glass-bonded mica. This substrate is coated with a thin, dielectric passivation layer which provides protection against mechanical and thermal stresses. The resistive layer is then laid onto the surface of the substrate. This resistive layer is usually composed of a mixture of tin oxide and nickel oxide films. The metal outer layer is usually made of pure metal or metal alloys and provides a conductive path between the substrate and the external connections.

The OM82G5E-R58 is suitable for high power applications due to its high temperature rating, high power dissipation and low temperature coefficient. It has a wide range of applications in the automotive, medical, communication, industrial and consumer electronics markets. This type of resistor has the ability to handle very high operating voltages, making it well suited for circuit protection and safety applications. Additionally, it can be used in the pulse and switching circuits of digital audio and video equipment.

The working principle of the OM82G5E-R58 involves the flow of current through the resistor core. When a current passes through the resistor core, its surface temperature increases, resulting in the output voltage decreasing. This decrease in voltage is called the diode’s voltage drop, which is related to the resistivity of the material of the resistor core. The greater the resistivity of the material, the higher the diode’s voltage drop. The OM82G5E-R58 has a low temperature coefficient, meaning that the difference between the output voltage and the ambient temperature is small.

In conclusion, the OM82G5E-R58 is a type of through hole resistor that is suitable for high power applications. It is characterized by high precision, high reliability and low temperature coefficient. It is commonly used in automotive, medical, communication, industrial and consumer electronics applications. The working principle of this type of resistor involves the flow of current through the resistor core, resulting in the output voltage decreasing in the presence of heat.
