Through Hole Resistors are small devices capable of converting electrical energy into resistant energy, limiting the flow of electrical current, and as a result, dissipating the energy produced by it to create heat. One of the main types of Through Hole Resistors is the ERG-2SJ302A, an extremely versatile device, which is used for various application fields, ranging from high-frequency circuits where high power dissipation is needed, to low-over-current application fields that require precise current limiting and temperature control. It is also widely used to add resistance to circuit designs, or as part of a voltage divider circuit. In this article, we will discuss the various application fields and working principles of the ERG-2SJ302A.
The ERG-2SJ302A has a versatile application field. Firstly, it can be used in high-frequency circuits where high power dissipation is needed, such as audio amplifiers, radio transmitters, digital signal processors, etc. Secondly, it can be used to limit the current and/or voltage in a low-over-current application field, such as low-power microcontrollers, small one-time battery powered applications, etc. Lastly, the ERG-2SJ302A can be used to add resistance to a circuit, or as part of a voltage divider circuit.
The working principle of the ERG-2SJ302A is quite simple. It uses two metal plates sealed in an epoxy resin body, similar to any other Through Hole Resistors. These metal plates are insulated from one another by a thin wall of epoxy insulation that is placed between the two plates. When power is applied to the terminals on the ERG-2SJ302A, the current will flow between the plates, causing a part of the current to be dissipated as heat. This is due to the resistance of the two plates, which limits the current flow through the ERG-2SJ302A.
As we have discussed, the ERG-2SJ302A is a highly versatile device, which can be used for a variety of applications. It is capable of providing precise current limiting and temperature control, and can be used for high-frequency circuits where high power dissipation is needed. Moreover, the ERG-2SJ302A can be used to add resistance to a circuit, or as part of a voltage divider circuit. The working principle of the ERG-2SJ302A is also quite simple, as it leverages the resistance of two metal plates, insulated from one another by a thin wall of epoxy insulation, to limit the flow of current and dissipate the energy produced by it as heat.
