.Through Hole Resistors, such as the RWR71S1400FRBSL, are resistors inserted into a hole on a printed circuit board (PCB). These resistors are designed to provide precision resistance and are commonly used in high-end audio applications requiring a tight range of resistance. The principle of operation is simple, but the technology behind it is very complex. The resistor is composed of two electrodes, the anode and the cathode, and a resistive element. When a voltage is applied across the resistor, the resistive element will act to reduce the flow of electric current to a predetermined amount. Through Hole Resistors not only allow for precise control over the flow of current, they also provide stability and reliability in the circuit.
RWR71S1400FRBSL Through Hole Resistors have a range of applications in audio, communications, industrial control, automotive and telecommunication systems. Specifically, they are used in applications requiring a precise amount of current regulation or voltage stabilization, for example in audio amplifiers, power supplies, motor controllers and signal processing systems. In these applications, the RWR71S1400FRBSL efficaciously provides the desired resistance needed, contributing to the overall stability and reliability of the system.
When designing a PCB, the size, shape, and number of Through Hole Resistors needed should be carefully considered. Different resistors require different sizes of holes, and multiple resistors can be combined into a single hole. Once a selection of the desired resistor is made, it must also be connected to the circuit board. The RWR71S1400FRBSL is designed with two contact pins that must be properly soldered onto the PCB. This, along with other Through Hole Resistors, provides a reliable connection and optimal current control.
The RWR71S1400FRBSL is designed to provide a precise amount of resistance under a given operating temperature and power dissipation. The range of usable temperatures for the RWR71S1400FRBSL ranges from -55 to +125 degrees Celsius, with a power dissipation of up to 1 Watt. High power dissipation ratings allow the RWR71S1400FRBSL to be used in instances with high power requirements, such as motor controllers, DC-DC converters, and high-end audio amplifiers.
Through Hole Resistors, such as the RWR71S1400FRBSL, are often preferred over surface mount resistors due to their high tolerance levels and superior quality. The RWR71S1400FRBSL provides precise control of current and is resistant to temperature and power fluctuations, making it an ideal solution for applications needing stable, reliable current regulation. Furthermore, the RWR71S1400FRBSL\'s two contact pins ensure a secure connection with the printed circuit board, providing a strong bond and reliable performance.
