What are the characteristics and differences between high-precision precision resistors and precision resistors Although high-precision resistors and precision resistors overlap in definition and characteristics, there are still some significant differences between them. Firstly, the resistance accuracy of high-precision precision resistors is higher, usually reaching ± 0.1% or lower, while the accuracy of precision resistors is usually between ± 1% and ± 0.1%. This means that high-precision resistors have more advantages in situations where extremely high precision is required.

Analysis of Silicon Carbide (SiC) Technology Barriers: What are the Silicon Carbide Technology Barriers Groove type silicon carbide power devices have greater manufacturing difficulty. According to the different device structures, silicon carbide power devices can be mainly divided into planar devices and trench devices. Flat silicon carbide power devices have good unit consistency, simple manufacturing process, but are prone to JFET effect and have high parasitic capacitance and on state resistance.
