Through Hole Resistors
The ERX-2SJ4R7A is a resistor type that can be found in a variety of places and devices. It is a type of through hole resistor, meaning that it is typically secured to the mounting surface, usually a printed circuit board, with a hole. The resistor is soldered into the circuit board and makes mechanical and electrical connections. Through hole resistors are one of the most common electronic components and can be used in almost any circuit.
The ERX-2SJ4R7A is an axial leaded resistor, meaning that two leads, or “legs”, extend from the body in opposite directions. It is typically composed of three layers, a ceramic core, a resistive film coating and an outer protective coating. The ceramic core is typically composed of an alumina ceramic, while the resistor layer is typically a layer of deposited metal that creates an electrical connection between the two legs. The outer layer typically provides protection against oxidation and wear.
The ERX-2SJ4R7A is designed to provide an adjustable level of resistance to the electric current passing through it. By adjusting the resistance, the voltage across the device can also be changed. This type of resistor can be used in a variety of applications such as voltage regulators, current limiters, and signal processing.
In addition, the ERX-2SJ4R7A has the ability to change the amount of resistance depending on the amount of current passing through it. This is known as “dynamic resistance” or “variable resistance”. The amount of current that can pass through the resistor is limited by the amount of resistance that the resistor offers. By adjusting the resistance, the amount of current that can pass through it can be changed.
The ERX-2SJ4R7A can be found in a variety of applications such as power supplies, communication systems and automotive electronics. Due to its adjustable resistance, the device is highly versatile and can be used in a wide variety of circuits. The device is typically manufactured using high-purity materials, which ensures reliable operation. It is also commonly used in microwave ovens, which require extreme precision and temperature stability.
The ERX-2SJ4R7A is also commonly used as an “overload protection” device because it can limit the amount of current passing through it and prevent damage to the circuit components. It is also used to reduce the amount of power consumed by the circuit and improve its efficiency. The device also has the ability to be connected in “parallel” and “series” to create specific voltage levels.
Overall, the ERX-2SJ4R7A is a versatile resistor type that can be used in a variety of applications. Its adjustable resistance, dynamic resistance, and overload protection capabilities make it ideal for a wide range of applications. It can also be connected in various configurations to create different levels of voltage and current, making it a highly useful and functional component.
