Through Hole Resistors
A through hole resistor is an electrical component used in circuits, particularly in wiring systems that need a large amount of electrical current. Essentially, a through hole resistor works by creating a resistance between two points of contact. This resistance in the current allows for the current to flow through the resistor, instead of directly through the wiring system. Through hole resistors can be used to reduce the amount of current that is flowing through the system, to reduce the amount of voltage passing through, and as an ammeter, which measures the amount of current passing through.
The RWR89S14R3FRBSL is an example of an application field specific through hole resistor. This resistor type is an economical solution to situations where there is a need for constant amperage, such as in load balancing, or where the current will change over time, such as in motor control systems. The RWR89S14R3FRBSL has a variety of features which make it an attractive solution: it has a slim profile design with a small footprint, it is encased in a durable case to protect it from moisture, and it has a high current capacity.
The working principle behind a through-hole resistor is based on the use of Ohm’s law. Ohm’s law relates the amount of current that can flow through a conductor to the voltage and the resistance. This law states that the current in a circuit is directly proportional to the voltage across it and inversely proportional to the resistance of the circuit. In other words, an increase in the resistance of a circuit will result in a decrease in the amount of current that is able to flow through it.
The RWR89S14R3FRBSL uses two embedded resistive elements to control the amount of current that passes through the resistor. One of the resistive elements, called the anode resistor, limits the amount of current that is allowed to pass through. This element is placed in series with the load circuit, creating a resistance that reduces the amount of current that is allowed to pass. The other element, the cathode resistor, limits the amount of voltage that is allowed to pass through the load circuit. This element is placed in parallel with the load circuit, reducing the amount of voltage that is allowed to pass.
The combination of the two resistive elements of the RWR89S14R3FRBSL allows the circuit to be operated within the limits set by Ohm’s law. By precisely controlling the amount of current and voltage that is allowed to pass through the resistor, the RWR89S14R3FRBSL ensures that the circuit is operated within the parameters of Ohm’s law, maximizing the efficiency of the circuit.
Through hole resistors are a cost effective way to add electrical protection to circuits that require a large amount of current. The RWR89S14R3FRBSL is an example of a through hole resistor designed specifically for this purpose, and its combination of a slim profile, durable case, and high current capacity make it an ideal choice for any application that needs a reliable and cost effective current limiting solution.
