TT Welwyn : High Power (3)
High Power Resistors are used to dissipate electrical energy or to to generate heat. Often used mounted to heatsinks, they require knowledge of thermal management.
Below 100 Watts standard semiconductor designs are normally used whereas larger Wattage designs normally utalise off-pcb designs such as Thick Film on Steel.
