Through Hole Resistors

Resistors are electronic components that resist the flow of electric current within a circuit. These components have an assigned resistance value, indicated in ohms, allowing them to control the current passing through them and thus modulate the voltage applied. The most common type of resistor is the through-hole resistor.A through-hole resistor is a resistor which is designed for mounting in printed circuit boards and uses a threaded mounting hole for securing the resistor to the board. They come in five different styles: axial, cylindrical, vertical, radial and vertical mounted. The various styles allow the resistor to fit into tight or difficult-to-access locations on circuit boards. The ERX-1SJR51 is an example of a through-hole resistor.The ERX-1SJR51 is a high-energy, wire-wound, ceramic core resistor. Its rated power is 1 watt, with a rating of 1/4W per resistor element. It has a dielectric strength of 3-5KV and is RoHS Compliant. It is typically used as a current limiter, load resistor, AC line filter, snubber, speed control and over-load protection resistor in industry automation applications. It is also suitable for medical equipment, lighting, communication, energy meters, and solar energy systems.The IRX-1SJR51 resistor is designed to provide reliable load and overload protection under high-voltage and current conditions. It is constructed with an electrodeposited nickel support and an enameled wire-winding around a ceramic core. This core acts as an insulating layer to prevent short circuit currents between the winding and the resistor body. The enameled wire winding becomes the resistor element, providing the desired resistance. The gold or tin plating of the contact poles improves contact connection to the electronic circuits and provides better connection reliability. The working principle of the ERX-1SJR51 is similar to any other type of resistor. When current passes through the resistor, it encounters resistance which causes a voltage drop proportional to the current. This voltage drop is usually referred to as the “Ohmic” voltage or the “Ohmic” drop across the resistor. This voltage drop is what helps regulate the flow of current in a given circuit. Additionally, the ERX-1SJR51 has several performance characteristics that enable it to maintain reliable operational stability in a variety of applications. These characteristics include minimal inductive characteristics, quick thermal response, stable capacitance and high insulation resistance. Further, due to its construction, the ERX-1SJR51 has superior electrical properties and can handle high-voltage and high-energy loads.In summary, the ERX-1SJR51 is a through-hole resistor which has a unique construction which, in turn, allows it to have superior electrical and thermal properties which make it suitable for industrial automation applications. Additionally, the working principle of the resistor is similar to any other type of resistor as it creates a voltage drop when current passes through it, thereby regulating the flow of current in a circuit and providing overload protection.
