What are Through Hole Resistors?

Through Hole Resistors (THRs) are electrical components used to control and limit the flow of electricity in electrical circuits. They are used across a variety of industries, and are comprised of a metal coil or wire, two ceramic insulators, a metal plate and a lead wire. THRs are sold in various sizes and shapes to accommodate differing lengths and shapes of wiring for various applications.

CW00191R00JE12HS: Application Field and Working Principle

The CW00191R00JE12HS Through Hole Resistor is an “axial” type of THR that has a body and two leads that extend out of each side. Being “axial” means it is designed to be connected horizontally – along the length of the body. The body itself is made of plastic, which gives the component greater heat and vibration resistance than other THR designs. This type of THR was specifically designed for use in audio applications, such as amplifiers, loudspeakers, head phones and microphones. The CW00191R00JE12HS THR typically has a resistance rating of 0.33Ω, and a power rating of 250 mW. It has a Tolerance of 5% and a maximum working voltage of 400 VDC. It also has a predictable temperature coefficient, which helps it to maintain consistent resistance values over time.The working principle of the CW00191R00JE12HS THR is based on Ohm’s Law, which states that “the current through a conductor between two points is directly proportional to the voltage across the two points.” In other words, when two points on a circuit are connected to the THR, the amount of current that flows between the points is restricted by the resistance of the THR. This happens because the THR restricts the flow of electrons in the circuit, resulting in a voltage drop. This voltage drop is directly related to the resistance of the THR.

Conclusion

The CW00191R00JE12HS Through Hole Resistor is a reliable and durable electrical component that is specifically designed for use in audio applications, such as amplifiers, loudspeakers, head phones and microphones. By restricting the flow of electrons between two points on a circuit, the THR steadily and predictably drops the voltage between the points, as dictated by Ohm’s Law. All THR components are designed with a unique set of characteristics, including resistance, power, voltage and temperature coefficients, which should be taken into consideration when selecting a component for a specific application.
