Through Hole Resistors are mechanical components that are designed to generate and provide electrical resistance within a given application. The FKN2WSFR-73-4R3 type through hole resistor is designed to provide a resistance level of 2.2 Watts at a given voltage level of 73 volts, with a maximum current rating of 4R3 Amps. The most popular application for such resistors is within electrical and electronic equipment, where they enable power management, signal conditioning,and protection of vulnerable circuitry.
The design of the FKN2WSFR-73-4R3 through hole resistor starts with a resistor core made of high-quality materials that are carefully selected to maximize long-term reliability and consistency of performance. This core is then wrapped with metal strips of fixed width. These strips are then enclosed in a sturdy plastic casing, which is hermetically sealed against moisture. The strips and casing are also designed to protect the resistor from impacts, temperature extremes and other forms of mechanical stress.
The working principle of the FKN2WSFR-73-4R3 through hole resistor is largely similar to other types of resistors in its class. When an electrical current passes through the resistor, the strip of metal works to resist that current. This resistance creates a generated voltage across the resistor that is proportional to the current flowing through it. This generated voltage is known as a ‘passive voltage’, and it is the main tool used to regulate electrical current across a circuit. By choosing the correct through hole resistor for a given application, the passive voltage generated by the resistor can be tailored to enable efficient and reliable power management.The FKN2WSFR-73-4R3 through hole resistor is best suited to applications where high-voltage and high-current solutions are required. The resistor is precise and dependable, allowing users peace of mind knowing that their apparatus and devices will operate to their maximum capability without the risk of overload. The resistor has also been designed to be highly reliable, with a lifespan of over 1000 hours under normal conditions. The resistor is becoming increasingly popular as a choice for modern applications, due to its reliable performance and robust construction.Overall, the FKN2WSFR-73-4R3 through hole resistor can be an effective solution for many applications that require a combination of high-voltage and high-current capabilities. The resistor is extremely reliable and its design is highly resistant to impact and stress. When used correctly, the resistor will provide consistent performance over a long period of time, allowing users to enjoy efficient and reliable power management.
