It is also used in RF applications due to its low noise and high EMI resistance. It is particularly well suited to applications that require high current and temperature capabilities.

Working Principle

The SFR25H0006981FR500 follows the same operating principle as all resistors. When a voltage is applied to the resistor, current passes through it, and some of this current is converted to heat which dissipates from the resistor. This heated energy is dissipated and converted to lower voltage levels which ultimately function to reduce the total current in the electrical circuit. This is how the resistor reduces the current and limits the voltage, allowing the users to better manage the flow of electricity in their circuits.
