Through Hole Resistors
A through hole resistor, also known as an axial resistor, is a two-terminal device used in electric circuits. It is made up of a cylindrical metal core with an insulating coating and two metal electrodes which protrude from its ends. It is essentially an electrical component that can resist the flow of electricity in a circuit. They are used to reduce the amount of current flowing through a circuit, or to control the amount of voltage present in a circuit. Through hole resistors are commonly used in circuits such as amplifiers, voltage regulators, signal generators and motor controllers.
W21-100RJI Application Field and Working Principle
The W21-100RJI is an axial resistors featuring high stability, low dissipation coefficient, low inductance and high accuracy. This product is suitable for applications requiring high power and robust performance, such as voltage and current regulation, impedance matching, circuit protection, and signal filtering. This resistor is also RoHS compliant for environmental protection.
The working principle of the W21-100RJI is simple – when a current passes through it, it experiences a resistance that generates heat. This dissipates the energy of the current flow, thus reducing the voltage and/or current present in the circuit. The resistance value of the resistor is typically indicated by several colored bands on the body, and it can range anywhere from 0.1Ω to 10MΩ. The W21-100RJI can handle up to 100 W of power.
The W21-100RJI stands apart from other through hole resistors due to its unique noise suppressing features. It also has excellent temperature coefficient of resistance (TCR), which means that its resistance stays consistent regardless of its operating temperature. Furthermore, its high flame-retardant properties make it an excellent choice for applications where safety is a priority.
Conclusion
The W21-100RJI is a through hole resistor that is suitable for a wide range of applications, particularly those that require high power and robust performance. Its excellent noise suppression features and high temperature coefficient of resistance make it an ideal choice for applications such as voltage and current regulation, impedance matching, circuit protection, signal filtering, and more. Despite its high-power capacity, it is also RoHS compliant for environmental protection.
