The resistive range of a power resistor ranges from less than 1Ω (R005) up to only 100kΩ as larger resistance values would require fine gauge wire that would easily fail. famous tax people

"Through-hole components typically have "leads" (pronounced /liːdz/) leaving the body "axially", that is, on a line parallel with the part's longest axis. Others have leads coming off their body "radially" instead. Other components may be SMT (surface mount technology), while high power resistors may have one of their leads designed into the heat sink.

WebApr 24, 2024 · by Annika Elsen. Comments 2. It’s an unfortunate fact that a resistor can fail under pulse loads. When pulse power is dissipated to the device’s resistive element, it generates heat and increases the resistor’s temperature. Overheating then damages the resistive element, leading to a resistance change or even the opening of the device.
