Aircraft Spark Plug – aircraftsparkplug
The silicon carbide resistor is voltage dependent. The higher the voltage, the lower its resistance. These devices exhibit high resistance until the voltage across them reaches a certain threshold, at which point their resistance drops to a lower level and maintains this level until the applied voltage drops.
Silicon Carbide SiC - STMicroelectronics
Silicon Carbide (SiC) is a wide bandgap material. Wide bandgap technologies have many advantages compared to Silicon. Operating temperatures are higher, heat dissipation is improved and switching and conduction losses are lower. However, wide bandgap materials are more difficult to mass produce compared to silicon based ones.
Varistor - Wikipedia
A varistor is an electronic component with an electrical resistance that varies with the applied voltage. Also known as a voltage-dependent resistor (VDR), it has a nonlinear, non-ohmic current–voltage characteristic that is similar to that of a diode.In contrast to a diode however, it has the same characteristic for both directions of traversing current.
