"WebWhen switching high-power MOSFETs or any low-speed circuits, the exact value of a gate resistor typically isn’t important. I usually use a 10R or 100R resistor and adjust it while testing if needed. When switching speeds approach several thousand Hz, it becomes important to do some calculations on what maximum-sized gate resistor to use. " - High side fet switch circuit
