ERX-1SJ2R2

Through Hole Resistors, such as ERX-1SJ2R2, are electronic components used to reduce electrical current and voltage, dissipate heat, modify impedance and form voltage dividers. They are typically composed of one or two resistive elements and are enclosed in a plastic casing that can be easily mounted to a board. They are most commonly used in circuits where limited power dissipation is desired and where chemical resistance is needed.

ERX-1SJ2R2 is an axial-type through-hole resistor that is a popular choice for a variety of applications. It has an operating temperature range of -65°C to +125°C, a rated power of 0.50W, and superior mechanical strength withstanding up to 5G\'s minimum acceleration. That makes it ideal for use in high vibration environments. It is also RoHS compliant and is highly resistant to fire, salt spray and shock.

The working principle of an ERX-1SJ2R2 is simple, yet incredibly important. When a voltage is applied to the resistor, it will resist the flow of current and produce a voltage drop as specified by Ohm\'s Law. This voltage drop will be across the resistor, meaning that the voltage applied to the resistor is greater than the voltage in the part of the circuit on the load side of the resistor. This effect, known as resistance, is essential for regulating the flow of current in a circuit.

In addition to regulating current and voltage, a through-hole resistor also dissipates power in the form of heat. This process is known as power dissipation; it occurs as a result of the resistor\'s design. As its name suggests, the resistor\'s body absorbs the heat, converting electrical energy into thermal energy.

Finally, through-hole resistors can be used to modify impedance. Impedance is defined as the total opposition to the flow of an alternating current. When applied to a circuit, impedance can be used to reduce the flow of unwanted current, as well as to suppress signals and noise.

In summary, ERX-1SJ2R2 is an axial-type through-hole resistor that is a popular choice for a variety of applications. It has superior mechanical strength, a rated power of 0.50W, and an operating temperature range of -65°C to +125°C. Its working principle is based on Ohm\'s Law, by which it resists current to produce a voltage drop and dissipates power in the form of heat. It can also be used to modify impedance and suppress signals and noise.
