HS300 20R F is a power resistor in Ohmite's HSS series, which is designed for high-power switching applications. It is a 10W rated, 3 ohm, through-hole surface-mount resistor with a maximum pulse power rating of 100W. The HS300 20R F features a heat-spreader design that disperses heat quickly, increasing the components life and improving ripple-noise performance and overload capability. It also features an extra high-temperature rating of 155°C, making it suitable for high-temperature applications.
